Why Testing?Why should I test my code ?
Reduce False assumptions -> If you rely on assumptions it will surely fail…
Validate that there is no regression
Make sure the code runs as expected
Test limit values (security,big data)
Automate repetitive tasks -> Good developers are lazy developers!!!
It makes debugging/correction so much easier
But…
Often developers finds it hard to write
Too long too run
Doesn’t correspond to business logic/behaviour/user scenario
CodeCeption(1)http://codeception.com/ (English)
Test Framework
Acceptance Tests
Functional Tests
Unit Tests
Easy
To read
To write
To debug
Natively handles PHPUnit -> standard
CodeCeption(2)BDD-style scenario-driver tests
WebServices tests (SOAP/REST/XML-RPC)
Generates reports(HTML/XML/JSON)
Laravel/Zend/Phalcon/Yii2/Symfony/Composer modules -> No excuse!
Integration with continuous deployment (Jenkins/Bamboo)
Can be used along with Selenium2 and PhantomJS for advanced tests
What does it look like?<?php $I = new AcceptanceTester($scenario); $I->wantTo('create wiki page'); $I->amOnPage('/'); $I->click('Pages'); $I->click('New'); $I->see('New Page'); $I->fillField('title', 'Hobbit'); $I->fillField('body', 'By Peter Jackson'); $I->click('Save'); $I->see('page created'); // notice generated $I->see('Hobbit','h1'); // head of page of is our title $I->seeInCurrentUrl('pages/hobbit'); $I->seeInDatabase('pages', array('title' => ‘Hobbit')); ?>

Function Testing
Acceptance Tests
Enable to do request and interact with the DOM
Use a fake browser to perform the queries
Can click and fill forms
Can be plugged with Selenium/PhantomJS to interact with JavaScript and screenshots
Slowest tests to run
Functional TestsSame as Acceptance test but does not use a browser
engine
Can be plugged with the framework to access internal functions and properties (Models, validation)
Use $_REQUEST, $_POST and $_GET
Faster
No DOM interaction (JS/Ajax/Events)
Unit TestsUsed to test functions Can be plugged with the framework to access internal functions and properties (Models, Validation) Fastest Difficult to use in MVC Not readable by Humans
public function testValidation() { $user = User::create(); $user->username = null; $this->assertFalse($user->validate(['username'])); $user->username = 'toolooooongnaaaaaaameeee'; $this->assertFalse($user->validate(['username'])); $user->username = 'davert'; $this->assertTrue($user->validate(['username'])); }
Install on all platformsMac OSX:
brew update && brew install homebrew/php/codeception
Linux:
wget http://codeception.com/codecept.phar .
php codecept.phar bootstrap
Windows:
php composer.phar global require “codeception/codeception:*”
Composer/ PhpStorm:
php composer.phar require “codeception/codeception:*”
Getting readyBootStrap
>codecept bootstrap
>codecept generate:cept acceptance Validation
Edit the configuration file : tests/acceptance.suite.yml
class_name: AcceptanceTester
modules:
enabled:
- PhpBrowser
- AcceptanceHelper
config:
PhpBrowser:

Let’s get the party started>codecept run
>codecept run —debug
Bonus
>codecept generate:scenarios acceptance //English version
>codecept console acceptance //Interactive console
>codecept run —debug —env test
Demo Time !!!!!> Let’s test PHP conference Kansai website !
Best practices1. Run tests on your vagrant -> GIT push ONLY when tests pass
2. Deploy on test server -> Validate tests on test server
3. Deploy on production ONLY if tests pass on test server
4. NEVER run on production ! NEVER!!!
1. It creates new entries and change Database
2. Add load on the production server
3. Need new set of tests/monitoring on production
