Codeception Testing Framework -- English #phpkansai

1. Text Introducing Codeception (TDD)—>Test Driven Development

2. Agenda Presentation of Speaker/ Company Presentation of Codeception Presentation of Tests Types Demonstration & Hands-on Best Practices References Q & A @phpcon_kansai

3. Who the hell am I ? Batard Florent (28 years old)(Shenril) Twitter: @shenril Facebook: Florent Btd Security Engineer (Ethical Hacker) French Globe Trotter Lived in France,UK,Switzerland,U.S,Japan Fan of Japan and especially Kansai area and people Style learning Japanese….

14. Who do I work for? Cook+biz Awesome Team Awesome Challenges

17. 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

18. 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

19. 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

20. 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')); ?>

28. 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

29. Functional Tests Same 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)

30. Unit Tests Used 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'])); }

31. Install on all platforms Mac 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:*”

32. Getting ready BootStrap >codecept bootstrap >codecept generate:cept acceptance Validation Edit the configuration file : tests/acceptance.suite.yml class_name: AcceptanceTester modules: enabled: - PhpBrowser - AcceptanceHelper config: PhpBrowser: url: ‘http://conference.kphpug.jp/2015/’

33. 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

34. Demo Time !!!!! > Let’s test PHP conference Kansai website !

35. Best practices 1. 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
