Behaviour-Driven Development
<?php
require_once 'PHPUnit/Extensions/Story/TestCase.php';
require_once 'BowlingGame.php';
class BowlingGameSpec extends PHPUnit_Extensions_Story_TestCase
{
/**
* @scenario
*/
public function scoreForOneSpareAnd3Is16()
{
$this->given('New game')
->when('Player rolls', 5)
->and('Player rolls', 5)
->and('Player rolls', 3)
->then('Score should be', 16);
}
// ...
}

Test Dependencies
<?php
class ExampleTest extends PHPUnit_Framework_TestCase
{
public function testOne()
{
$this->assertTrue(FALSE);
}
/**
* @depends testOne
*/
public function testTwo()
{
}
}
?>
