13. THIS TALK IS NOT…
REFACTORING
DEPENDENCY INJECTION, DECOUPLING, ENCAPSULATION, TESTABLE CODE

14. WHAT IS CODECEPTION?
A SIMPLE BDD STYLE TESTING FRAMEWORK
WHICH IS EASY TO READ, WRITE AND DEBUG

15. YOU WRITE IN YOUR FAVORITE EDITOR

16. COMPOSER INSTALL CODECEPTION/CODECEPTION
VENDOR/BIN/CODECEPT BOOTSTRAP

17. ACCEPTANCE.SUITE.YML

modules:
enabled:

18. PAGE USED FOR TESTING

19. CODECEPT GENERATE:CEST ACCEPTANCE HOME
public function seeIfNameExists(AcceptanceTester $I)
{
$I->wantTo('see if conference name exists');
$I->amOnPage(‘/');
$I->click(‘#rt-logo‘);
$I->see('zendcon');
}

20. STEPS

21. CODECEPT GENERATE:STEPOBJECT ACCEPTANCE <NAME>
GENERATED FILE EXTENDS ACCEPTANCETESTER CLASS

22. REUSE CODE FOR DIFFERENT TESTS
class CompareSteps extends AcceptanceTester {
public function seeIfNameExists()
{
$I = $this;
$I->amOnPage('/');
$I->see('zendcon');
}
}
class MenuCest {
public function seeIfNameExistsViaCCStep(CompareSteps $I)
{
$I->seeIfNameExists();
}
}

23. PAGE OBJECTS

24. CODECEPT GENERATE:PAGEOBJECT ACCEPTANCE <NAME>
GENERATED FILE IS JUST A CONTAINER

25. PAGE OBJECT CONTAINER
class HomePage
{
public static $URL = '/';
… // removed code for slide layout purposes
public static function of(AcceptanceTester $I)
{
return new static($I);
}
public function see($value)
{
$I = $this->acceptanceTester;
$I->amOnPage(self::$URL);
$I->see($value);
}
}

26. USE THE OBJECT IN A TEST
public function seeIfNameExistsViaPageObject()
{
HomePage::of($this)->see('zendcon');
}

27. VERSION COMPARISON

28. MASTER !== RELEASE/NEXTGEN
FROM A TECHNICAL PERSPECTIVE

29. MASTER === RELEASE/NEXTGEN
FROM A FUNCTIONAL PERSPECTIVE

30. ATTENTION PLEASE
LOST OF CODE COMING UP…

31. OVERRIDE DEFAULT CRAWLER
public function getHtmlFromContent(InnerBrowser $innerBrowser, $css)
{
$crawler = $this->getCrawler($innerBrowser);
$selector = CssSelector::toXPath($css);
$value = $crawler->filterXPath($selector);
return $value->html();

{
$reflection = new ReflectionClass(get_class($innerBrowser));
$property = $reflection->getProperty('crawler');
$property->setAccessible(true);
return $property->getValue($innerBrowser);
}

32. CREATE SECOND PHPBROWSER INSTANCE
protected function getPhpBrowserByPage($page) {
$phpBrowser = $this->getAlternatePhpBrowser();
$phpBrowser->amOnPage($page);
return $phpBrowser;
}
protected function getAlternatePhpBrowser() {
$config = Configuration::config();

$options['url'] = $options['alternate-url'];
$phpBrowser = new PhpBrowser($options)->_initialize();
$this->setProxyInGuzzle($phpBrowser->guzzle);
return $phpBrowser;
}

33. GET HTML OF BOTH VERSIONS
public function getHtml($page, $path)
{
$I = $this;
$I->amOnPage($page);
return $this->getHtmlFromContent(
$I->fetchModule('PhpBrowser'), $path);
}
public function getAlternateHtml($page, $path)
{

$this->getPhpBrowserByPage($page), $path);
}

34. ADDING ALTERNATE URL
class_name: AcceptanceTester
modules:
enabled:
- PhpBrowser
- AcceptanceHelper
config:
PhpBrowser:
url: 'http://www.zendcon.com/'
alternate-url: 'http://zendcon.com'

35. COMPARING 2 VERSIONS IN 1 RUN
public function seeSameOnVersions($page, $path, $altPath, $message)
{
$I = $this;
list($left, $right) = $this->getContentFromVersions(
$page, $path, $altPath);
$I->seeEquals($left, $right, $message);
}
public function getContentFromVersions($page, $path, $altPath)
{
return array(
$this->getHtml($page, $path),
$this->getAlternateHtml($page, $altPath)
);
}

36. TEST PAGE HEADER
public function seeIfPageHeaderIsIdentical(CompareSteps $I)
{
$I->seeSameOnVersions(
HomePage::$URL,
'h2',
'h2',
'Homepage header not identical'
);
}

37. TEST SIGNUP FORM
public function seeIfFormActionIsIdentical(CompareSteps $I)
{
$I->seeSameOnVersions(
HomePage::$URL,
'.rsformbox1',
'.rsformbox1',
'Homepage signup form not identical'
);
}

38. TEST SIGNUP FORM
public function seeIfFormActionIsIdentical(CompareSteps $I)
{
$I->seeSameOnVersions(
HomePage::$URL,
'.rsformbox1',
'.rsformbox1',
'Homepage signup form not identical'
);
}
<div class="rsformbox1 title3">
