The document discusses introducing Codeception, a PHP testing framework. It begins with an agenda that includes a presentation on Codeception, different test types, a demonstration, and best practices. It then introduces the speaker, Florent Batard, who is a security engineer and web developer from France. He explains why testing is important for reducing assumptions and validating that code runs as expected. The bulk of the document then focuses on Codeception, explaining what it is, how it works, the different types of tests it supports including acceptance, functional, and unit tests, and how to install and use it. Code examples are provided and it concludes with referencing materials and opening the floor for questions.

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'));
?>

Function Testing

29. 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

30. 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)

31. 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']));
}

Composer/ PhpStorm:
php composer.phar require “codeception/codeception:*”

33. 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/’

34. 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

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

36. 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
