Automating Web Performance Data Collection with Behat and BrowserMob Proxy

30 Oct

BrowserMob Proxy is a utility which is used for capuring HTTP traffic and performance data from the browser. BrowserMob-Proxy adds in essential missing capabilities such as checking HTTP status codes and injecting headers for HTTP Basic Auth. Web Perfomance data can be manually captured by other tools like Firebug or Developers Tools. Using BrowserMob Proxy we can capture perfonace data in HAR format while running automated tests. There is lots of food to learn about BrowserMob on thier official website.

In this article, we will see how to integrate BrowserMob Proxy with Behat. In order to get started we need to install PHPBrowserMob package.

PHPBrowserMob

$ sudo pear channel-discover element-34.github.com/pear
$ sudo pear install -f element-34/PHPBrowserMobProxy
$ sudo pear install -f element-34/Requests

Download latest version of the BrowserMob Proxy from the site. You can launch BrowserMob proxy like this

$ cd browsermob-proxy-2.0-beta-6/
$ cd bin
$ sh browsermob-proxy -port 9090

You will see something like this:

$ sh browsermob-proxy -port 9090
INFO 10/30 21:29:50 o.b.p.Main           - Starting BrowserMob Proxy version 2.0-beta-6
INFO 10/30 21:29:51 o.e.j.u.log          - jetty-7.3.0.v20110203
INFO 10/30 21:29:51 o.e.j.u.log          - started o.e.j.s.ServletContextHandler{/,null}
INFO 10/30 21:29:52 o.e.j.u.log          - Started SelectChannelConnector@0.0.0.0:9090

This means, BrowserMob Proxy is running correcrtly.

Download and start selenium version 2.25.0. Note that, proxy won’t work for some version of selenium server. Better Download latest.

$ java -jar selenium-server-standalone-2.25.0.jar

Now, We need to install Behat by following official doc Or just follow my previous post on Behat installtion with composer.

$ sudo mkdir Behat-BrowserMob
$ sudo chmod -R 777 Behat-BrowserMob
$ cd Behat-BrowserMob/
$ behat --init

Now create a feature file for exporting the performance data in the HAR format.

$ sudo vim BehatBrowserMob.feature
 Feature: BrowserMob Proxy with Behat
In order to check website performance
As a automated tester
I need to see network traffic captured in the HAR format

@javascript
Scenario: Behat Bowsermob
Given I setup BrowserMobProxy
And I Navigate to "http://www.facebook.com/"
When I export HAR
Then I should see network traffic in the HAR file

You need to include ‘PHPWebDriver‘ and ‘PHPBrowserMobProxy‘
We can implement the feature using following code :

<?php

use Behat\Behat\Context\ClosuredContextInterface,
Behat\Behat\Context\TranslatedContextInterface,
Behat\Behat\Context\BehatContext,
Behat\Behat\Exception\PendingException;
use Behat\Gherkin\Node\PyStringNode,
Behat\Gherkin\Node\TableNode;
use Behat\MinkExtension\Context\MinkContext;

require_once __DIR__ . '/PHPBrowserMobProxy/Client.php';
require_once __DIR__ . '/php-webdriver/PHPWebDriver/WebDriver.php';
require_once __DIR__ . '/php-webdriver/PHPWebDriver/WebDriverProxy.php';
require_once 'PHPUnit/Framework/Assert/Functions.php';
require_once 'PHPUnit/Autoload.php';

/**
* Features context.
*/
class FeatureContext extends BehatContext {

protected static $driver;
protected static $BrowserMob;
protected static $BrowserMobSession;
public $data;

/**
* Initializes context.
* Every scenario gets it's own context object.
*
* @param array $parameters context parameters (set them up through behat.yml)
*/
public function __construct(array $parameters) {

}

/**
* @BeforeScenario
*/
public function cleanup() {
$HARFile = "/tmp/BROWSERMOBHAR.php";
if (file_exists($HARFile)) {
echo "The file $HARFile exists, I am going to delete it \n";
unlink($HARFile);
}
}

/**
* @Given /^I setup BrowserMobProxy$/
*/
public function iSetupBrowsermobproxy() {
self::$driver = new PHPWebDriver_WebDriver();
self::$BrowserMob = new PHPBrowserMobProxy_Client("localhost:9090");
$additional_capabilities = array();
$webDriverProxy = new PHPWebDriver_WebDriverProxy();
self::$BrowserMob->new_har("google");
$webDriverProxy->httpProxy = self::$BrowserMob->url;
$webDriverProxy->add_to_capabilities($additional_capabilities);
$this->session = self::$driver->session('firefox', $additional_capabilities);
}

/**
* @Given /^I Navigate to "([^"]*)"$/
*/
public function iNavigateTo($url) {

$this->session->open($url);
}

/**
* @When /^I export HAR$/
*/
public function iExportHar() {
file_put_contents("/tmp/BROWSERMOBHAR.php", var_export(self::$BrowserMob->har, true));
}

/**
* @Then /^I should see network traffic in the HAR file$/
*/
public function iShouldSeeNetworkTrafficInTheHarFile() {
assertFileExists('/tmp/BROWSERMOBHAR.php');
}

}

Now, run ‘behat’ and watch the test running in the Browser. You will find data stored in the ‘/tmp/BROWSERMOBHAR’ file. You can use HAR viewer to see performance data in fancy way !

There are number of possibilities you can use this data. Here is best article which describe use of HAR file.

  • Calculate Load time.
  • Set/Get HTTP Headers during your tests
  • Capture performance data with HAR files.
  • Simulate network traffic and latency
  • Rewrite HTTP requests and respones

SourcCode on GitHub:

Source Code is available on GitHub repo ‘Behat-BrowserMobProxy‘ . Just give it a try !

Final Thoughts:

Combination of Behat, WebDriver and BrowserMob Proxy can be used for capturing the network trafic while running automated tests. We can use HAR files as per our need eg. Calculate Page load times, Page performance analysis etc etc..

Behat2.4 : Painless installation with Composer

31 Aug

Behat is a BDD framework for PHP application. Behat has becoming so popular in recent days. Behat has drastic changes in recent days in order to add some cool features into it.

One of the amazing feature is, behat installation with use of Composer. Composer is dependency manager for PHP application which helps us to manage all the third party dependencies at one place and use them properly. Another great feature behat added is ‘Behat Extensions’. You can extend behat by adding extensions of your choice.

In this tutorial, we will see how to upgrade Behat vesion with use of composer . Most of us have been installed Behat with ‘pear’ packages. behat version installed with pear has no longer supported. Read Behat installation guide for further information.

Now, get ready to uninstall old version of behat and install new one. Open your terminal and type in following comands.

Check your existing installation,

Shashi-MacBook-Pro:~ user$ which behat

You will see something like this, if you have installed Behat with pear

Shashi-MacBook-Pro:~ user$ which behat
/usr/local/pear/bin/behat

Remove this Behat vesion by typing

Shashi-MacBook-Pro:~ user$ sudo pear uninstall behat/behat
Password:
uninstall ok: channel://pear.behat.org/behat-2.3.5

Remove ‘Gherkin’ package

Shashi-MacBook-Pro:~ user$ sudo pear uninstall behat/gherkin
uninstall ok: channel://pear.behat.org/gherkin-2.1.1

Remove ‘Mink‘ as we are going to use ‘MinkExtension’


Shashi-MacBook-Pro:~ user$ sudo pear uninstall behat/mink
uninstall ok: channel://pear.behat.org/mink-1.3.3

MinkExtension creates Mink instance in each sub-context or it could be even used as subcontext on its own.
You can read more about it on MinkExtension documentation.

Behat 2.4 installation

As we have just removed old version of behat, so we won’t find anything in binary when you execute ‘behat’ command

Shashi-MacBook-Pro:~ user$ behat
-bash: /usr/local/pear/bin/behat: No such file or directory

Now create new Behat installation Direcory, I have created in /opt/behat like this

Shashi-MacBook-Pro:~ user$ sudo mkdir /opt/behat

Shashi-MacBook-Pro:~ user$ cd /opt/behat/
Shashi-MacBook-Pro:behat user$ sudo chmod 777 /opt/behat/

Create ‘composer.json’ file with all the required dependencies like this

Shashi-MacBook-Pro:behat user$ sudo vi composer.json

Insert following dependencies in the json file, you can add more

{
"require": {
"behat/behat": "2.4.*@stable",
"behat/mink": "1.4@stable",
"behat/mink-goutte-driver": "*",
"behat/mink-selenium-driver": "*",
"behat/mink-selenium2-driver": "*",
"behat/mink-extension": "*",
"behat/mink-sahi-driver": "*"

},
"minimum-stability": "dev",
"config": {
"bin-dir": "bin/"
}
}

Note that we have included ‘Mink Extension’ as well in the dependencies. Now download the composer and intstall dependencies.

Shashi-MacBook-Pro:behat user$ ls
composer.json

 

Shashi-MacBook-Pro:behat user$ curl http://getcomposer.org/installer | php
% Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

#!/usr/bin/env php
All settings correct for using Composer
Downloading...

Composer successfully installed to: /opt/behat/composer.phar
Use it: php composer.phar

This will download ‘composer.phar’ file. Check it

Shashi-MacBook-Pro:behat user$ ls
composer.json    composer.phar

Now install it using


php composer.phar install

This will download all the dependencies. You can see it in the ‘Behat’ directory.

Shashi-MacBook-Pro:behat user$ ls
bin        composer.json    composer.lock    composer.phar    vendor

Now, you are ready to run Behat using ‘bin/behat’ command.

Shashi-MacBook-Pro:behat user$ ./bin/behat

You will see something like this in the output. This means you have installed behat successfully !!

Shashi-MacBook-Pro:behat user$ ./bin/behat

[RuntimeException]
Context class not found.
Maybe you have provided wrong or no `bootstrap` path in your behat.yml:
http://docs.behat.org/guides/7.config.html#paths

behat [--init] [-f|--format="..."] [--out="..."] [--lang="..."] [--[no-]ansi] [--[no-]time] [--[no-]paths] [--[no-]snippets] [--[no-]snippets-paths] [--[no-]multiline] [--[no-]expand] [--story-syntax] [-d|--definitions="..."] [--name="..."] [--tags="..."] [--cache="..."] [--strict] [--dry-run] [--rerun="..."] [--append-snippets] [features]

Check Behat version


Shashi-MacBook-Pro:behat user$ ./bin/behat --version
Behat version DEV

Make Behat Global

Now Create a global symlink to access behat from anywhere

Shashi-MacBook-Pro:behat user$ sudo ln -s /opt/behat/bin/behat /usr/local/bin/behat

You can run behat from anywhere. It completes Behat2.4 installation process.

Note: You may need to restart your terminal session but not nessessarily.

Shashi-MacBook-Pro:bin user$ which behat
/usr/local/bin/behat

Enjoy New Behat !! 

Enjoy ‘MinkExtension’ for Behat

7 May

‘

Note : This post may not work with recent Behat. Please use and my  Github repo for to get it working without any issue https://github.com/Shashikant86/BehatDemo

MinkExtension‘ has been just released which has additional services for Behat. This extension has ‘Mink’ instance for your ‘FeatureContext’ and ‘SubContext’. UI testers would be happy now, as they don’t need to create Mink instance every time in order to use Mink API’s.

Well, in order to use ‘MinkExtension’ you need latest Behat and Mink versions (Behat 2.4+ and Mink 1.4+). Don’t worry so much about the versions,  creator of Behat has taken care of all this with composer.

Ok. Let’s clone the MinkExtenion-Example repository from GitHub. See, everything is mentioned in README file.

This is time to update your PHP version. If you still want run features with same PHP version, then comment out/ remove everything from ‘TraitedFeatureContext.php’ which is for PHP5.4

Now,  Start Selenium server & Run behat with ‘inheritance’  or  ‘subcontext’ profile.

./bin/behat -p=inheritance

./bin/behat -p=subcontexts

You will see test running with headless as well as with browser. You will see output like this

moonstar:MinkExtension-example sjagtap$ ./bin/behat -p=subcontexts
Feature: Search

What’s new for Testers in MinkExtension?

  • You will get Mink instance in your ‘FeatureContext’ as well as ‘SubContexts’ classes.
  • You can extend Base Contextfile to MinkContext as shown in below. For other context you need to extend from RawMinkContext
class MyContext extends Behat\MinkExtension\Context\MinkContext
  • You can use MinkExtension as a SubContext in your files like this:
class SubcontextedFeatureContext extends Behat\Behat\Context\BehatContext
{
public function __construct()
{
$this-&gt;useContext('mink', new Behat\MinkExtension\Context\MinkContext);
}

This extension is a base for future extensions. We can extend Behat/Mink with any other services testing services like SauceLabs and many more.  This feature will definitely useful for Web Testers using Behat and Mink for browser automation. SauceLabs extension is on it’s way..  stay tuned🙂

Happy BDD !!!

Adding More Sauce To Behat

24 Apr

 

Note : This post may not work with recent Behat. Please use and my  Github repo for to get it working without any issue https://github.com/Shashikant86/BehatDemo

 

Further to my previous post regarding ‘Behat-Sauce’ integration, ‘Adding Sauce To Behat‘, I am glad to know that there is another Behat and SauceLabs integration from Laura Beth. Thanks a lot Laura for that excellent effort.

On the occasion of Selenium Conference, I met with Noah Sussman talking about “Selenium In the Enterprise: What Went Right, What Went Wrong (So Far)” and one of his slides indicated that, team using Behat and Mink for the functional testing at Etsy. Noah then introduced me to Laura Beth who setup Behat/Mink and SauceLabs integration. Behat-Sauce configuration by Laura Beth is very easy to use.

Now, we will see this in action.

Behat Installation 

Create a ‘Demo’ directory  and Clone the repository from Laura Beth’s GitHub account

moonstar:~ sjagtap$ mkdir Demo
moonstar:~ sjagtap$ cd Demo
moonstar:Demo sjagtap$ git clone https://github.com/elblinkin/Behat-Sauce.git

Writing lock file
Generating autoload files

You have just installed Behat and all dependencies. Now initialize project by running ‘bin/behat-sauce –init’ command.

moonstar:Behat-Sauce sjagtap$ ./bin/behat-sauce --init
+d features - place your *.feature files here
+d features/bootstrap - place bootstrap scripts and static files here
+f features/bootstrap/FeatureContext.php - place your feature related code here
+d config - edit you config settings here
+f /Users/sjagtap/Demo/Behat-Sauce/configbehat.yml - place your feature related code here

Once you initialized ‘Behat’. It will ‘features’ and ‘features/bootstrap’ directories and ‘features/bootstrap/FeatureContext.php’ file for you.

Feature file

You can also see ‘config’ directory with ‘behat.yml’ file for you. You need to add SauceLabs ‘Username’ and API key to the ‘behat.yml’.

Now write a simple feature file and save it to ‘features’ directory.

Feature: wikiSearch
  In order to search information on wiki
  As a Wiki user
  I want to get sensible results from site

  @javascript
  Scenario Outline: Search Keywords on wiki
    Given I am on "/"
    And I fill in searchBox with "<input type="text" />"
    When I press search button
Then I should see "<output>"

 Examples:
 | input | output |
 | London | lʌndən/ |

Step Definition

You need implement step definitions using Mink API’s. You feature context file will look like this now.

<!--?php use Behat\Behat\Context\ClosuredContextInterface,     Behat\Behat\Context\TranslatedContextInterface,     Behat\Behat\Exception\PendingException; use Behat\Gherkin\Node\PyStringNode,     Behat\Gherkin\Node\TableNode; use Behat\Sauce\Context\SauceContext; /**  * Features context.  */ class FeatureContext extends SauceContext {     /**      * Initializes context.      * Every scenario gets it's own context object.      *      * @param   array   $parameters     context parameters (set them up through behat.yml)      */     public function __construct(array $parameters) {         parent::__construct($parameters);     } /**      * @Given /^I fill in searchBox with "([^"]*)"$/      */     public function iFillInSearchboxWith($input)     {         $this--->fillField("searchInput",$input);
    }

    /**
     * @When /^I press search button$/
     */
    public function iPressSearchButton()
    {
        $this->getMink()->getSession()->getDriver()->click("//*[@id='searchButton']");
         $this->getMink()->getSession()->wait("3000");
    }
}

Well, now you are ready to run your tests on SauceLabs just by running

moonstar:Behat-Sauce sjagtap$ ./bin/behat-sauce

You will see test running on the SauceLabs. Once tests finished running, you will see output like this:

moonstar:Behat-Sauce sjagtap$ ./bin/behat-sauce

SeleniumConf came to London!

23 Apr

As mentioned on the Selenium Conference 2012 website, this year conference would be across the pond and it was London.  Conference venue ‘IET London‘ was amazing place situated on the bank of Thames river and great view of historical London Eye. I live and work in London so it’s very convenient for me to get down to the location of the conference. I met with with selenium users all across the world and shared thoughts and ideas about open-source testing. Selenium conference started on Monday April,16 and wrapped up on Wednesday, April,18. I spend three memorable days at Selenium conference and learned a lot about new tools, methodologies and approaches of testing applications with Selenium. I would like to take this opportunity to thank SauceLabs and all other sponsors of the Selenium Conference.

Let me see, how can I explain what happened in the conference.

WORKSHOP DAY

It was drizzling, when I came out of the Embankment tube station, and need to walk for 2-3 minutes to get to the venue. It wasn’t difficult to find venue and reception of the Selenium conference. I met with Ashley Wilson, (Customer Development Manager at SauceLabs) at registration desk. Ashley played key role in organizing and managing Selenium Conference. then I didn’t forget to pick a T-Shirt labeled with ‘Selenium Conference 2012’. The breakfast and tea was ready.

It was difficult to choose a workshop as both were interesting. I decided to go for workshop ” Contributing to Selenium” by ‘WebDiver Guy‘ (Simon Stewart) in the morning session.

“Contributing to Selenium” Workshop

The workshop aimed at contribution to selenium open-source project. I was ready with all the code downloaded from googleCode and brand new IntelliJ IDE.  I have heard about cool features of the IntelliJ but never tried it before. It is really awesome. Simon already mentioned in technical requirements that ‘ Setting up project in Eclipse is not supported’.

Within the workshop, I had a look at directory structure of the selenium codebase, setup the project in the IntelliJ and also done some code modifications as suggested by Simon. At the middle of the workshop, I was lagging behind while running the JavaScript tests. I ran build with ‘build.desc’ file also ran some test with Firefox driver. Lately, I realised that I was surounded by ‘software engineer in test’ from Google. Lucky me !!

After the break, we started with running tests within IDE. Being new to the ItelliJ, I faced some issues while running tests but managed to get it worked with the help of Simon.  At the end of the workshop, someone asked question about ‘How to measure coverage of the Selenium/Functional tests’  and there were interesting discussion around this topic. Being from PHP background, I couldn’t resist myself to ask about ‘PHP Webdriver bindings and current development on PHP bindings’. Simon said ” In terms of PHP, FaceBook-Webdriver bindings are recommended”. Simon then introduced me to Damien Sereni who works in Facebook. At the end of the session. Me and Demien spend some time discussing about future of the PHP webdriver bindings also shared contact details. The lunch was waiting for us then.

After lunch, again I had to make tough decision about selecting workshop. I have decided to go to “If Ikea made instructions for Selenium (or: How to fix bugs in Selenium for yourself)” by  Daniel Wagner-Hall, and the Selenium Committers. I really missed the another one “Handmade Etsy Tests” by  Stephen Hardisty & Michelle D’Netto. Lately realised that Etsy uses Behat and Mink for functional testing which is interesting topic for me which I missed a lot.

How to fix bugs in Selenium for yourself

In this workshop, Daniel talked about selenium codebase and different drivers. I have already checked out selenium trunk in my system and need to look into Selenium bugs to pick up. Being a tester and having limited development knowledge, I realised that I can’t fix any bug in selenium so just started doing some interesting stuff. I managed to get the tests running on my Andriod phone with the help of Andriod driver. That was enough for me it this session and it was end of first day of the selenium conference.

TUESDAY, APRIL 17

April,17 is my birthday. I reached early on that day in order to register my unconference talk on “Behat and Sauce Labs Integration”. I registered my talk at 10PM  on that day. I was very excited to talk on the occasion of my birthday.

Anyway, I saw huge crowd on second day of the conference and met with people from different countries while having tea and breakfast. At 9 PM, we get into the lecture hall, which was huge and amazing. There was one tweet from Frisco Del Rosario (@frdelrosario) saying ” Auditorium at #SeConf had balconies, microphones at each chair, flawless wi-fi. http://twitpic.com/9c30la“

As per the schedule, Jason and Simon introduced sponsors and explained schedule of Track A and Track B talks.

Testing Rapidly Changing Applications With Self-Testing Object-Oriented Selenium Infrastructure

Most people turned on for Track B talk which was on ” Testing Rapidly Changing Applications With Self-Testing Object-Oriented Selenium Infrastructure”  by  Dan Cuellar. I also headed over to that talk. Slides of his talk are available on here Dan explained how to test rapidly changing applications with just small code change in the test infrastructure. Dan implemented object oriented approach that can handle such a rapid change. As per the Dan if you abstracted the code well then you can build robust automated test scripts. Dan is looking for someone who can help him to extend his work to support iOS. If you are interested to help him then email him at danc@zoosk.com

Web acceptance Testing with Behat

After Dan’s talk, it was my turn to give talk on ‘Web Acceptance Testing with Behat’. There was another Track A talk where Anand Ramdeo was talking about “One Step At a Time” most people turned out there. I was bit disappointed seeing only 10 people attending my talk but still I carried it forward. My talk covered BDD and ATDD with the Behat, Sauce Labs , Jenkins and Relish. Slides of my talk are available here.

So you’re automated… now let’s make it fast!

I have decided to stay at Track B where Sauce Ninja Santiago was about to talk on making test automation fast. The title of his talk was ” So you’re automated… now let’s make it fast!”. Santiago shared some tips to make selenium tests faster like avoiding static waits in the tests or running tests in parallel. At the end of the Santiago’s talk, there are couple of raised which sounds interesting to Santiago. There was a question from Mitch about database integration with selenium tests which was interesting. I asked question about flaky tests that fails in the cloud complaining “element not found” but works well in local machine. As per Santiago, it’s bit tricky to judge random failures in browsers in the cloud.

Using Selenium to Improve a Team’s Development Cycle

After the break, I headed over to lecture hall to hear Mike Devis talking about “Using Selenium to Improve a Team’s Development Cycle“. Mike shared some cool tips about improving quality of the functional tests. Mike also talked about involving developers to write tests. I really like the idea of profiling the tests.  Ultimately, it was very pleasant talk with lots of good tips

Geb: Very Groovy Browser Automation

This is one of the best talk from my point of view. Thanks to Luke Daley. This talk was about Geb. Geb is a browser automation framework which combines cool features of WebDriver, jQuery and the Page Objects. Most interesting thing, I found in this talk is $() method. The dollar method can be used to interact with the web pages and accessing web elements. Another interesting thing is integration of Geb with different frameworks like JUnit, TestNG, Spock, Cucumber. At the end of the talk, I asked question on integration of Geb with new Cucumber JVM. Once Luke finished his talk, we went to reception to have a lunch.

Robots: If You Can’t Beat ‘Em, Build ‘Em

Well, This was most interesting demo to watch that how Jason “Teach Robot to play Angry Bird“. Click the link and watch the video inside the presentation, you will be amazed by seeing that how it can be achieved with Selenium. I think, only God and Jason knows how to write code for this. I just enjoyed the demo and applauded at the end of talk.

Building Quality with Foundations of Mud

After Jason’s talk, Kristian Rosenvold was talking about ‘Building Quality’. Kristian explained how to build test environment, test data and Continuous Integration practices in order to build quality products. He again explained some cool tips to handle flaky tests and errors. His slides are explanatory. Kristian made one statement who liked by selenium contributors. It was “Make your dev team live and Breathe the build”  At the end of the presentation, I asked question on Tolerance rate of their functional tests. Kristian answered that they can tolerate failing integration tests but not the functional tests. Well, then it was time for quick break then.

Massively Continuous Integration

Continuous Integration is area of my interest so I didn’t want to miss talk on my favorite topic. I headed over to the Track B where Jesse Dowdle & David Tolley were talking on their huge continuous integration system. As per their slides, they have reduced cycle time of running tests from 3 days to 30 minutes. The amount of selenium tests and cycle time to run them over Grid literally amused me. They used Jenkins and amazon web for running the tests. I would rather recommend looking at the slides of the presentation. It was amazing talk.I would like to see demo how they run massive test suite within 30 mins. Thanks to speakers & Jenkins.

How to Test the Inside of Your Head

Speaker Liz Keogh is vary famous agile/BDD coach and international speaker. I was impressed by her talks on BDD at Skills Matter. No wonder her talk at Selenium Conference was one the best. Liz talked about collaboration between developers, testers, BA, project managers and customers. As per Liz “Testers are Evil so let them think before writing code“.  Most of people on twitter channel were saying it was brilliant talk.

Well, how can I forget that there was amazing party sponsored by FaceBook at the GlassHouse Store, London. I met with people all around world and had great chat with them. Food and drinks were amazing. Great opportunity to celebrate birthday with unlimited drinks and food. Thanks Facebook.

WEDNESDAY, APRIL 18

Last day of the selenium conference was full of interesting talks, lighting talks and end up with closing keynote session. At the start of the day ‘ Simon Stewart’ kicked off with his talk on status of Selenium projects since last selenium conference

State of the Union

Simon didn’t forget to mention that he is on twitter (@shs96c) at the start of his talk. Simon highlighted recent enhancements of the Selenium project. He also point out an year in a browser and new selenium committers. The most interesting part of his presentation was his analysis of job trends in year, the graph amused everyone.

Simon addressed future development will be on mobile drivers as they are being valuable in recent days. He also expecting new stuff with respect to W3C standard. Let’s see how it will go on in near future. Slide of his talks are available here.

After Simon’s talk I headed over to Track B where “TFT Test Automation Framework” talk was going on. It was all about maintaining and writing automated tests just by using spreadsheets.  I really missed “Introducing Selenium Builder – the Future of Test Development” talk by Adam Christian and David Stark. Hope to see videos of the talk soon.

Selenium in the Enterprise: What Went Right, What Went Wrong (So Far)

Noah Sussman  was talking about how they used selenium at Etsy. This talk was more about test maintenance and test infrastructure at Etsy. Being a big fan of Behat, I came across one the slide saying “Etsy used Behat & Mink for functional testing”. I was keen to know more about that and asked question on how they used behat in their projects also had a chat after talk with Noah.

 Automated Security Testing

Alan Parkinson was talking about  ‘Zed Attack Proxy (ZAP) Web-Driver’ for automated security testing. Alan introduced ZAP during his talk and then integrated with build system like ANT. Alan’s demo of ZAP and Jenkins was amazing. I couldn’t resist myself to tweet about that. It’s great approach to perform automated security check on build. I will definitely give a try.

Pluggable Test Infrastructure

As far I remember, I have seen video of last selenium conference Dima talking about Selenium and Cucumber. This year Dima and Jeff comes up with Pluggable Test Infrastructure. They are using Cucumber, Capybara and webdriver at Groupon. Jeff said that using Cucumber is debatable. Jeff & Dima combined API tests, iPhone tests, Sauce tests and Selenium tests with Cucumber. It would be interesting to see demonstration of how they achieved this.

Speed up Your Selenium Tests with PhantomJS, the Headless Browser

Ivan De Marino was then talking about PhantomJS  in order to make selenium tests fast. In his talk he showed how you could run selenium tests with PhantomJS and Ghostdriver. Ghostdriver is wire protocol on PhantomJS. One of the tweet was saying Ghostdriver has awesome potential but needs your contribution. If you wish to contribute then fork Github repo now.

Robot Framework

Once Ivan finished his talk on PhantomJS, I have decided to go for Track B where Philip Noetzel was talking about “Robot Framework: Semicolon free testing”. I heard a lot about Robot Framework but didn’t got chance to look into it. This talk was very beneficial for me as Philip shows some cool stuff about robot framework and also shown sample code. Philip also shared his thoughts about pros and cons of using Robot framework. At the end of the presentation we asked Philip if we can use Robot framework for PHP applications.

More Than Automation – How Good Acceptance Tests Can Make Your Team Happier

I was keen to hear Matt Wynne, author of Cucumber book talking about ‘More Than Automation‘. Matt introduced Mortgage Driven Development (MDD) where developers try to make feature completely readable and unmaintainable in order to save your job!. Matt also added concept of “Refuctoring” where developers try to add brittle steps and scenarios in order to make it messy. Well, Matt also said ” Cucumber is a threat” but then audience understood whats intention behind all this idea. As per Matt, Cucumber is cool take which allow everyone to collaborate and write tests. Matt also suggest to read Cucumber book in order to get yourself familiar with Behavior Driven Development (BDD). Matt shared cool tool for living documentation called ‘Relish’. At the end of the talk, there were couple of question around Relish. one of them was asked by me.

Lightning Talks

There were about 10  lightning talks (including mine) scheduled on the board and each one of 5 minutes. Lightning talks was fun. I liked Anand and Komal talked about how to do things wrong. It was nice talk. I am keenly waiting to see videos of Lightning talks.

Closing Keynotes

After the lighting talks there were another session called ‘Closing Keynotes’ where all the selenium committers discuss about the future enhancements and answered questions. There was one interesting question comes up in this session about Selenium 3. Conference was then wrapped up by thanking everyone who attended the conference.

SELENIUM CONFERENCE LIVE WITH #SECONF

 I bet, everyone who attended conference had loads of fun and learned new things. Those were was not able to attend the conference, they got live conference updates from twitter hashtag #SeConf. I got a tweet from Michelle Flynn (@MichelleFlynn) saying “Great twitter chat about #SeConf, love how you can follow a conference even if you cannot attend”

Many people all over the world was getting updates on selenium conference every minute. Thanks to organizers for creating such a unique hashtag also thanks to all twitter users who twitted in #SeConf

Interesting things I found.

  • Mortgage Driven Development
  • Mobile Drivers
  • Use of BDD tools with Selenium like Cucumber, SpecFlow, Behat
  • Geb: Very groovy browser automation framework
  • ‘Atkins’ plug-in for Jenkins
  •  Robot Framework for BDD and DDD
  • Large scale Continuous Integration with Jenkins and Amazon cloud services

CONCLUSION

Selenium conference taught me lot of new things around Selenium also given an opportunity to meet with Selenium users all across the globe which was amazing experience. Great speakers, great learning experience and amazing location. Thanks SauceLabs, Google and all other sponsors. Looking forward next year !

PHPUnit + Behat/Mink + Page Object: The Rockstar Combination of Testing

7 Apr

Last month, we had discussion about implementing page object pattern in Behat/Mink framework at London Behat Users meetup . Page object pattern is a cool way to make tests maintainable, reusable and readable. Everyone was interested to know more about Page Object Pattern.

In this short tutorial, we will implement Mink and PHPUnit  combination for functional testing. Mink and PHPUnit combined with Pageness (Page Object) can be used for maintainable and readable tests. Mink is a web acceptance testing framework for PHP application. Mink has clean API’s which allows browsers emulation and browser controls. Mink has headless browser emulators as well as browser controls which covers all browsers interactions. PHPUnit is testing framework for PHP applications.

Installations

Lets start with some installations assuming PHP, Pear package is already installed.

Install PHPUnit

Now, upgrade pear package & install PHPUnit

$ pear update-channels
$ sudo pear channel-discover pear.phpunit.de
$ sudo pear channel-discover pear.symfony-project.com
$ pear channel-discover components.ez.no
$ sudo pear install –alldeps phpunit/PHPUnit
$ phpunit --version

Install Behat/Mink

$ pear channel-discover pear.symfony.com
$ pear channel-discover pear.behat.org
$ pear install behat/mink

Mink is ready to use just including in PHP classes.

require_once 'mink/autoload.php';

PHPUnit-Mink Framework on GitHub

PHPUnit-Mink framework designed to use combination of PHPUnit, Mink and Page Object Pattern to write functional tests with various browser emulators like Goutte, Selenium, Sahi and WebDriver. PHPUnit-Mink Framework has used Mink and PHPUnit to write tests. Driver support for Selenium, Sahi, WebDriver for browser emulation. Test Report Generation which can plugged in Continuous Integration server. Page Objects which can be used directly in tests. Abstracted common elements up in the framework in order to make it maintainable.

How to use:

  • Clone GitHub Repository
$git clone git@github.com:Shashi-ibuildings/PHPUnit-Mink.git
$cd PHPUnit-Mink
  • Start your Driver

Sahi Driver :

Download sahi zip file from SourceForge

Now launch Sahi Server using command below:

$ cd /path/to/sahi
$ cd userdata/bin
$./start_sahi.sh

Selenium Driver:

You need to download selenium server jar file and execute following command:

$ cd /path/to/selenium-server
$java -jar selenium-server-standalone-2.20.0.jar

In this tutorial, we are using sahi driver.

  • Now run tests using ANT
$cd /path/to/PHPUnit-Mink
$ant Mink

Directory structure

  1. conf    : YAML files can be used with Behat
  2. core    : Abstracted common elements/ methods
  3. Page   : Page objects (reusable Methods for page)
  4. report :  Generate Junit, Agile doc reports
  5. tests    :  PHPUnit tests using Mink Api’s

Don’t forget to include Mink and PHPUnit in Test like this:

<?php
require_once 'mink/autoload.php';
use Behat\Mink\Mink,
Behat\Mink\PHPUnit\TestCase;

Page Objects Pattern

There are some areas within application UI where your test interacts with. These areas can be identified by their functionality, they offer e.g login, registration, search etc. Page object pattern models as a object within you test code. While writing tests, we just need to create an object of the page and access methods and variables withing that page objects. This approach is useful when UI changes, we need to make changes in page objects not in the tests. Tests become readable and maintainable using page objects.

Page objects classes generally:

  1. Set of public methods that page offer which can be reused later.
  2. don’t make any assertion. Assertions can be added later into tests not in the page objects
  3. checks if user is on the same page that page object is created.
  4. don’t represent entire page but some important functions of that particular page.

GitHub & Other sources of Page object pattern

Read more about page object on  google wiki. There are couple of GitHub repositories that explains page object pattern, Saunter and pelenium

Writing Page Objects:

Common methods can be abstracted in the ‘page’ directory. You can specify driver of your choice. Now we have test with Sahi session. Example page looks like this

<?php
require_once 'mink/autoload.php';
use Behat\Mink\Mink,
Behat\Mink\PHPUnit\TestCase;
require_once 'core/core_PHPUnitMink_CommonElementFunctions.php';
class page_search extends TestCase
{
function search($input)
{
$this->getSession('sahi')->getPage()->fillField("searchInput",$input);
$this->getMink()->getSession('sahi')->getDriver()->click("//*[@id='searchButton']");
$this->getMink()->getSession('sahi')->wait("3000");
}
}
?

Using Page Objects in Tests

You can use pages just by creating new objects and accessing variables,methods in the test. Example of test looks like this

<?php
class wikiSearchTest extends core_PHPUnitMink_CommonElementFunctions
{
protected static $mink;</pre>
public function testwikiSearchsingle()
 {
 $page = new page_search($this):
 $page->visit();
 $page->search(“mumbai”);
<pre>assertEquals(“Mumbai”, $page->findFirstHeading()));
}

Writing Data-Driven Tests

You can write data driven tests by using PHPUnit and Mink combination. Data can be placed in CSV or in an array. Example data-driven test looks like this

<?php
class wikiSearchTest extends core_PHPUnitMink_CommonElementFunctions
{
protected static $mink;
function searchData() {
return array(
array('london','London'),
array('newyork','New York')
);
}
/**
*
* @param &lt;type&gt; $searchfor
* @param &lt;type&gt; $expectedResult
* @dataProvider searchData
*/

public function testwikiSearchMultiple($input,$output)
{
$this->getSession('sahi')
->visit('http://en.wikipedia.org/wiki/Main_Page');
$this->getSession('sahi')->getPage()->fillField("searchInput",$input);
$this->getMink()->getSession('sahi')->getDriver()->click("//*[@id='searchButton']");
$this->getMink()->getSession('sahi')->wait("3000");
assertEquals($output, $this->getMink()->getSession('sahi')->getDriver()->getText(".//*[@id='firstHeading']/span"));
}

}

Starting Engines

Before running tests, you need to start Mink drivers, here we are using Sahi. You can update tests to run Selenium driver. Launch driver from command line like this:

  • Sahi : Navigate to Sahi directory and run:
moonstar:~ sjagtap$ cd sahi/userdata/bin/
moonstar:bin sjagtap$ ./start_sahi.sh
--------
SAHI_HOME: ../..
SAHI_USERDATA_DIR: ../../userdata
SAHI_EXT_CLASS_PATH:
--------
Sahi properties file = /Users/sjagtap/sahi/config/sahi.properties
Sahi user properties file = /Users/sjagtap/sahi/userdata/config/userdata.properties
Added shutdown hook.
&gt;&gt;&gt;&gt; Sahi started. Listening on port: 9999
&gt;&gt;&gt;&gt; Configure your browser to use this server and port as its proxy
&gt;&gt;&gt;&gt; Browse any page and CTRL-ALT-DblClick on the page to bring up the Sahi Controller
-----
Reading browser types from: /Users/sjagtap/sahi/userdata/config/browser_types.xml

Running Tests with PHPUnit

Now you can run wikisearch test with PHPUnit like this :

moonstar:PHPUnit-Mink sjagtap$ phpunit tests/wikiSearchTest.php

Temporary SauceLabs fork 3.5.24 of PHPUnit by Sebastian Bergmann. Supports parallel testing. Becomes obsolete when PHPUnit 3.7.0 is released.

...

Time: 33 seconds, Memory: 11.25Mb

OK (3 tests, 3 assertions)

Running Tests with Ant

You can run tests using apache ANT. Navigate to project root directory (PHPUnit-Mink) and run an

moonstar:PHPUnit-Mink sjagtap$ ant Mink
Buildfile: /Users/sjagtap/PHPUnit-Mink/build.xml
[delete] Deleting directory /Users/sjagtap/PHPUnit-Mink/report
[mkdir] Created dir: /Users/sjagtap/PHPUnit-Mink/report

Mink:
[exec]
[exec]
[exec]
[exec]
[exec] Temporary SauceLabs fork 3.5.24 of PHPUnit by Sebastian Bergmann. Supports parallel testing. Becomes obsolete when PHPUnit 3.7.0 is released.
[exec]
[exec] ....
[exec]
[exec] Time: 45 seconds, Memory: 11.75Mb
[exec]
OK (4 tests, 4 assertions)

BUILD SUCCESSFUL
Total time: 46 seconds
moonstar:PHPUnit-Mink sjagtap$

Once all tests finished running, you will see build successful message. This build can be easily plugged into Continuous Integration server like Jenkins.

Conclusion:

Functional testing become much easier with use of Mink with PHPUnit. Page Object pattern can be used with PHPUnit-Mink to make tests reusable and readable.

You can find source code on GitHub PHPUnit-Mink repository. Happy PHP Testing !

Behat-SauceLabs Integration on GitHub

17 Mar

Behat is a new generation Behavior Driven Development tool for PHP applications. Behat is inspired by Ruby’s Cucumber. Behat can be used for web acceptance testing by using Mink. Mink uses browser emulators like Selenium, Sahi, WebDriver to launch browser.

SauceLabs is cloud testing service which allow selenium based tests into cloud machine with different browser combination. Create an account with Saucelabs and you will definitely love it

To install and setup Behat project, read SauceLabs blog ‘Adding Sauce To Behat‘.

Let’s directly move on to code. I assume you have installed Behat and Mink as per the blog ‘Adding Sauce To Behat’.

You can use code available on GitHub project ‘Behat-Sauce‘ directly into your project.

Requirement:

*Behat/Mink Installed

*Ant

*SauceLabs Account (Username and API Key)

*Jenkins (optional)

How to use?

* Clone the repository from my GitHub

   
$ git clone git@github.com:Shashi-ibuildings/Behat-Sauce.git
$ cd /path to/Behat-Sauce

* Edit ‘Sauce.yml’ file in order to specify your username and API key.

* Now, Run ANT command to execute feature on sauce Labs

   
$ ant runSauce

* Once All tests executed see the reports generated in ‘report/report.html’ file.

*  Use it in your project by updating ‘behat.yml’ and ‘sauce.yml’. Change Base url to your application url.

* Write and implement features in ‘features’ directory.

You can setup your Jenkins Continuous Integration server by following the blog post ‘Adding Sauce To Behat’

Don’t invest your time/money and effort in setting up different machine/browser combinations for cross browser testing. Better to use SauceLabs.

Any questions? Let me know.

Behat Meetup in a nutshell

17 Feb

Note : This post may not work with recent Behat. Please use and my  Github repo for to get it working without any issue https://github.com/Shashikant86/BehatDemo

 

On Feb 15, we had a great evening at Ibuildings, London office. We organized the first ever Behat meetup in the United Kingdom. A group  called “London Behat Users” organized an event to demonstrate Behavior Driven Development for the PHP developers and testers who wish to get started with Behat.

Behat is an amazing BDD framework for PHP developers which works exactly the same as Cucumber. Assuming that PHP developers and testers are new to BDD, we made the agenda ‘Behat from Scratch‘. There were about 15 behat users who attended this event.

As per the schedule, we had great Pizza before kick-off. While having drinks and Pizza, An Event organizer, Mitch asked everyone to introduced themselves and asked about their experience with Behat. All members were keen to know about other behat users and how long they have been using behat and BDD. After introductions, I explained a little bit about the ‘London Behat users’ group.

Live Coding (Developers View)

Jakub Zalas kicked it off with a talk about the developer’s view in BDD projects. He started the demonstration with a short introduction to BDD, how BDD is different from TDD and so on. Jakub covered following topics while coding:

1. Behat/Mink Installation

Jakub created composer.json file in the project root:

Then he downloaded composer.phar and ran install command which installed all the dependencies of Behat as well as Mink.

2. Creating first project

Once he was done with all the installations, he created a project called “Behat From Scratch” and initialized behat using:

$ behat --init
+d features - place your *.feature files here
+d features/bootstrap - place bootstrap scripts and static files here
+f features/bootstrap/FeatureContext.php - place your feature related code here

The theme of the application was very simple. There was a form with two fields called ‘Title” and ‘Body” and a button called “Preview.” When a user fills in data in the ‘Title’ & ‘Body” fields and clicked on the “Preview” button, then the user should see the text that they entered.

3. Writing first Gherkin feature

Next he wrote one Gherkin feature file with couple of scenarios:

Feature: Previewing article
As a Content Manager
I want to preview an article before saving it
In order to make sure it is displayed correctly

Scenario: Article is displayed in a preview area
Given I visit "article form"
And I fill in "Hello Behat!" for "Title"
And I fill in "BDD is fun" for "Body"
When I press "Preview"
Then I should see "Hello Behat!" in the preview area
And I should see "BDD is fun" in the preview area

Scenario: Preview is not visible initially
Given I visit "article form"
Then the preview area should not be visible

After that, he implemented Step Definitions for the integrated classes based on the Silex micro-framework, uses Twig templates and Symfony‘s form component. He implemented all the step definitions until all the steps passed.

The Source code of this is available on GitHub: Behat From Scratch

Browser Automation with Mink (Testers View)

Once Jakub finished with implementation, he handed it over to me to explain how to do browser automation using Mink. I modified the ‘config/behat.yml’ file and tagged the scenarios with ‘@javascript’ tags.

I also explained how to run feature files using different Mink drivers. Behat has provided lot of driver options for testers. It is not limited to Selenium. It has following mink drivers.

Selenium Server

You need to download the selenium server jar file and execute the following command:

$ cd /path/to/selenium-server
$java -jar selenium-server-standalone-2.15.0.jar

Sahi Server

Download the sahi zip file from SourceForge

Now launch Sahi Server using the command below:

$ cd /path/to/sahi
$ cd userdata/bin
$bash start_sahi.sh

There was a quick demonstration of the tests running in browsers using the Selenium 1, 2 (WebDriver), and Sahi servers. This was followed by a short question and answer session.

Try this on your own

You may be interested in trying all this stuff on your own. Jakub mentioned all of the instructions in his GitHub project. I will briefly explain the steps to follow:

$ moonstar:~ sjagtap$ git clone git://github.com/jakzal/behat-from-scratch.git
      Cloning into behat-from-scratch...
      remote: Counting objects: 123, done.
      remote: Compressing objects: 100% (59/59), done.
      remote: Total 123 (delta 47), reused 123 (delta 47)
      Receiving objects: 100% (123/123), 63.34 KiB, done.
      Resolving deltas: 100% (47/47), done.
      moonstar:~ sjagtap$ cd behat-from-scratch/
  • Install Behat with Composer
    Download the Composer and install Behat:
$ moonstar:behat-from-scratch sjagtap$ wget  http://getcomposer.org/composer.phar
% Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
Dload  Upload   Total   Spent    Left  Speed
       100  308k  100  308k    0     0   366k      0 --:--:-- --:--:-- --:--:--  582k

$moonstar:behat-from-scratch sjagtap$ php composer.phar install

Here, you may face some problems while installing, depending on your network and permission issues. (There may be a bug in composer.)

I managed to install it properly and it’s up and running in my localhost. You need to cross your fingers at this point.
By default the custom  Silex micro-framework session is used so there’s no need for additional configuration. Behat will create a Silex application and simulate requests.

All the project’s scenarios can be run with:

$ moonstar:behat-from-scratch sjagtap./bin/behat
  As a Content Manager
I want to preview an article before saving it
In order to make sure it is displayed correctly

Scenario: Article form is accessible from the homepage # features/previewing-article.feature:7
Given I visit "homepage"                             # FeatureContext::iVisit()
When I follow "Add article"                          # FeatureContext::clickLink()
Then I should see "Title" input on the article form  # FeatureContext::iShouldSeeInputOnTheArticleForm()
And I should see "Body" textarea on the article form # FeatureContext::iShouldSeeTextareaOnTheArticleForm()

Scenario: Article is displayed in a preview area       # features/previewing-article.feature:14
Given I visit "article form"                         # FeatureContext::iVisit()
And I fill in "Hello Behat!" for "Title"             # FeatureContext::fillField()
And I fill in "BDD is fun" for "Body"                # FeatureContext::fillField()
When I press "Preview"                               # FeatureContext::pressButton()
Then I should see "Hello Behat!" in the preview area # FeatureContext::iShouldSeeInPreviewArea()
And I should see "BDD is fun" in the preview area    # FeatureContext::iShouldSeeInPreviewArea()

Scenario: Preview is not visible initially             # features/previewing-article.feature:23
Given I visit "article form"                         # FeatureContext::iVisit()
Then the preview area should not be visible          # FeatureContext::thePreviewAreaShouldNotBeVisible()

Scenario: Title and body are required                  # features/previewing-article.feature:28
Given I visit "article form"                         # FeatureContext::iVisit()
When I press "Preview"                               # FeatureContext::pressButton()
Then I should see "Article title is required"        # FeatureContext::assertPageContainsText()
And I should see "Article body is required"          # FeatureContext::assertPageContainsText()
And the preview area should not be visible           # FeatureContext::thePreviewAreaShouldNotBeVisible()

You don’t need to configure the web server to run scenarios using Silex driver.  But you do need to configure the web server while running tests in browser.

Configure Web Server.

Follow these steps to configure the web server.

  1. Update ‘hosts’ file and add ‘behat.dev’ and IP as follows
$moonstar:~ sjagtap$ cd /etc
$moonstar:etc sjagtap$ sudo vi hosts
# Host Database
     # localhost is used to configure the loopback interface
     # when the system is booting.  Do not change this entry.
      ##
    127.0.0.1       localhost
    127.0.0.1  behat.dev
  • Make sure you have updated ‘/etc/apache2/httpd.conf’ to enable virtual host. Remove the comment from Virtual hosts.
$moonstar:~ sjagtap$ cd /etc/apache2/
$moonstar:apache2 sjagtap$ cat httpd.conf
 # Virtual hosts
     Include /private/etc/apache2/extra/httpd-vhosts.conf
  • Now you need to update the ‘/etc/apache2/extra/httpd-vhosts.conf ‘ file and add the following configuration to it:
$mmoonstar:~ sjagtap$ cd /etc/apache2/extra/
$moonstar:extra sjagtap$ sudo vi httpd-vhosts.conf
     VirtualHost *:80;
ServerName behat.dev

DocumentRoot /var/www/behat.dev/web
DirectoryIndex index.php

Directory /var/www/behat.dev/web&gt;
Options FollowSymLinks
AllowOverride All
Order allow,deny
allow from all
/Directory&gt;
     /VirtualHost&gt;

You are done with web server configuration, and now you can run your tests through a browser.  The Paths to source code and a domain name will have to be updated. Also the base_url in  ‘config/behat.yml’ needs to be changed accordingly.

Run Tests in Browser

  • Tag all your scenarios with ‘@javascript’ tags
  • Run Selenium server as mentioned above
$ cd /path/to/selenium-server
$java -jar selenium-server-standalone-2.15.0.jar
  • Update ‘config/behat.yml’
default:
context:
parameters:
default_session: goutte
javascript_session: webdriver
browser: firefox
               base_url: http://behat.dev/
  • Run ‘./bin/behat’ from a terminal and watch results in browser.
$ moonstar:behat-from-scratch sjagtap./bin/behat
Feature: Previewing article
As a Content Manager
I want to preview an article before saving it
In order to make sure it is displayed correctly

Then I should see "Title" input on the article form  # FeatureContext::iShouldSeeInputOnTheArticleForm()
And I should see "Body" textarea on the article form # FeatureContext::iShouldSeeTextareaOnTheArticleForm()

@javascript
Scenario: Article is displayed in a preview area       # features/previewing-article.feature:14
Given I visit "article form"                         # FeatureContext::iVisit()
And I fill in "Hello Behat!" for "Title"             # FeatureContext::fillField()
And I fill in "BDD is fun" for "Body"                # FeatureContext::fillField()
When I press "Preview"                               # FeatureContext::pressButton()
Then I should see "Hello Behat!" in the preview area # FeatureContext::iShouldSeeInPreviewArea()
And I should see "BDD is fun" in the preview area    # FeatureContext::iShouldSeeInPreviewArea()

@javascript
Scenario: Preview is not visible initially             # features/previewing-article.feature:23
Given I visit "article form"                         # FeatureContext::iVisit()
Then the preview area should not be visible          # FeatureContext::thePreviewAreaShouldNotBeVisible()

@javascript
Scenario: Title and body are required                  # features/previewing-article.feature:28
Given I visit "article form"                         # FeatureContext::iVisit()
When I press "Preview"                               # FeatureContext::pressButton()
Then I should see "Article title is required"        # FeatureContext::assertPageContainsText()

Discussion about Behat and BDD

After we finished with the demo, we started a discussion about BDD and behat. To me, this was the most interesting part of the meetup. Lot of things about BDD, tester-developer collaboration, acceptance criteria, Jenkins and other CI systems were discussed.

Some of the highlights of the discussion are as follows:

  • Ben and Jakub Zalas  shared thoughts about test reporting with Jenkins. (using HTML reports).
  • Mitch raised points about making scenarios and running scenarios with different data sets and everybody contributed
  • Marcello talked about the role of testers and developers in BDD
  • Miles and Alex raised some good questions about web testing using Gherkin DSL.
  • John played a key role within the whole session talking about collaborative tools, challenges in BDD and some tricks about BDD.

Conclusion:

The first Behat meetup was an amazing experience for all the attendees. Everybody learned by sharing experiences and ideas. In short, all of us enjoyed our evening of knowledge sharing. We are looking forward to arrange monthly meetups to further discuss Behat and BDD.  The next meetup is tentatively scheduled for Wed Mar 21 at 7:00 PM (GMT). Click here for details.

Many Thanks to the creator of Behat: ‘Konstantin Kudryashov‘

 

Happy BDD !!
