1. VfsStream effective filesystem mocking Sebastian Marek

3. basic knowledge of PHPUnit

5. SOAP

6. 3 rd party

8. Many different ways

9. Not a dependency REALLY!?

10. Learning by example <?php class Config { private $filename ; public function __construct($filename) { if (!is_file($filename)) { throw new Exception( &quot;Can't set the filename - it doesn't exists!&quot; ); } $this -> filename = $filename; } public function fetchConfig() { return parse_ini_file( $this -> filename , true ); } public function createCacheDir($directory) { if (!is_dir($directory)) { return mkdir($directory, 0700, true ); } return false ; } }

12. prepare upfront http://picasaweb.google.co.uk/catof.airsoft/PartisanRusse#5480348761446205778

13. guerrillas test case <?php class ConfigTest extends PHPUnit_Framework_TestCase { private $cacheDir = '/tmp/cache' ; private $configFile = '/tmp/config.ini' ; // (...) /** * @covers Config::__construct */ public function testConstructorSetsConfigFilename() { $config = new Config( $this -> configFile ); $this ->assertAttributeEquals( $this -> configFile , 'filename' , $config); } // (...) }

14. guerrillas test case <?php class ConfigTest extends PHPUnit_Framework_TestCase { private $cacheDir = '/tmp/cache' ; private $configFile = '/tmp/config.ini' ; // (...) /** * @covers Config::__construct */ public function testConstructorThrowsExceptionWithInvalidConfigFile() { $configFile = '/share/usr/config.ini' ; $this ->setExpectedException( 'Exception' , &quot;Can't set the filename - it doesn't exists!&quot; ); $config = new Config($configFile); } // (...) }

15. guerrillas test case <?php class ConfigTest extends PHPUnit_Framework_TestCase { private $cacheDir = '/tmp/cache' ; private $configFile = '/tmp/config.ini' ; protected function setUp() { $content = &quot; [section1] key1=value1 key2=value3 [section2] key3=value3 &quot; ; file_put_contents( $this -> configFile , $content); if (!is_dir( $this -> cacheDir )) { mkdir( $this -> cacheDir ); } } // (...) }

16. guerrillas test case class ConfigTest extends PHPUnit_Framework_TestCase { private $cacheDir = '/tmp/cache' ; private $configFile = '/tmp/config.ini' ; // (...) protected function tearDown() { if (is_dir( $this -> cacheDir )) { rmdir( $this -> cacheDir ); } unlink( $this -> configFile ); } // (...) }

18. uses php stream wrapper http://picasaweb.google.co.uk/dawson.jerome/MCASMiramarAirShow2007#5121760885155756402

19. vfsStream installation #> pear channel-discover pear.php-tools.net #> pear install pat/vfsStream-alpha

20. vfsStream - register <?php require_once 'vfsStream/vfsStream.php' // (...) protected function setUp() { vfsStream:: setup ( 'root' ); } // (...)

21. vfsStream & PHPUnit <?php class SomeTest extends PHPUnit_Framework_TestCase { protected function setVfsStream() { @ include_once 'vfsStream/vfsStream.php' ; if (!class_exists( 'vfsStreamWrapper' )) { $this ->markTestSkipped( 'vfsStream is not available - skipping' ); } else { vfsStream:: setup ( 'root' ); } } public function testSomething() { $this ->setVfsStream(); //(...) } }

22. vfsStream – working with files <?php class ConfigTest extends PHPUnit_Framework_TestCase { /** * @covers Config::__construct */ public function testConstructorSetsConfigFilename() { $this ->setVfsStream(); vfsStream::newFile( 'config.ini' )->at(vfsStreamWrapper::getRoot()); $config = new Config(vfsStream::url( 'root/config.ini' )); $this ->assertAttributeEquals(vfsStream::url( 'root/config.ini' ), 'filename' , $config); } // (...) }

23. vfsStream – working with files <?php class ConfigTest extends PHPUnit_Framework_TestCase { /** * @covers Config::__construct */ public function testConstructorThrowsExceptionWithInvalidConfigFile() { $this ->setVfsStream(); $this ->setExpectedException( 'Exception' , &quot;Can't set the filename - it doesn't exists!&quot; ); $config = new Config(vfsStream::url( 'root/config.ini' )); } // (...) }

24. vfsStream url <?php // (...) public function dumpVfsStreamUrl () { $this ->setVfsStream(); echo vfsStream::url( 'root/config.ini' ); // vfs://root/config.ini } // (...) }

25. vfsStream – working with dirs <?php class ConfigTest extends PHPUnit_Framework_TestCase { /** * @covers Config::createCacheDir */ public function testCreateCacheDirIfItDoesntExists() { $this ->setVfsStream(); $this ->assertFileNotExists(vfsStream:: url ( 'root/cache' )); vfsStream:: newFile ( 'config.ini' )->at(vfsStreamWrapper:: getRoot ()); $config = new Config(vfsStream:: url ( 'root/config.ini' )); $config->createCacheDir(vfsStream:: url ( 'root/cache' )); $this ->assertFileExists(vfsStream:: url ( 'root/cache' )); } // (...) }

26. vfsStream – working with dirs <?php class ConfigTest extends PHPUnit_Framework_TestCase { /** * @covers Config::createCacheDir */ public function testDontCreateCacheDirIfItExists() { $this ->setVfsStream(); vfsStream:: newFile ( 'config.ini' )->at(vfsStreamWrapper:: getRoot ()); vfsStream:: newDirectory ( 'cache' )->at(vfsStreamWrapper:: getRoot ()); $this ->assertFileExists(vfsStream:: url ( 'root/cache' )); $config = new Config(vfsStream:: url ( 'root/config.ini' )); $result = $config->createCacheDir(vfsStream:: url ( 'root/cache' )); $this ->assertFalse($result); } // (...) }

27. vfsStream – working with content <?php class ConfigTest extends PHPUnit_Framework_TestCase { /** * @covers Config::fetchConfig */ public function testFetchConfigReturnsArray() { $this ->setVfsStream(); $content = << < 'EOT' [section1] key1 = value1 [section2] key2 = value2 [section3] key3 = value3 EOT; vfsStream:: newFile ( 'config.ini' )->withContent($content) ->at(vfsStreamWrapper:: getRoot ()); $config = new Config(vfsStream:: url ( 'root/config.ini' )); $result = $config->fetchConfig(); $this ->assertTrue(is_array($result)); $this ->assertEquals(3, count($result)); $this ->assertEquals( array ( 'key1' => 'value1' ), $result[ 'section1' ]); $this ->assertEquals( array ( 'key2' => 'value2' ), $result[ 'section2' ]); $this ->assertEquals( array ( 'key3' => 'value3' ), $result[ 'section3' ]); } }

28. vfsStream – file perms new vfsStreamFile( 'app.ini' , 0644); new vfsStreamDirectory( '/home' , 0755); vfsStream:: newFile ( 'app.ini' , 0640); vfsStream:: newDirectory ( '/tmp/cache' , 0755); $vfsStreamFile->chmod(0664); $vfsStreamDirectory->chmod(0700);

29. vfsStream – file ownership $vfsStreamFile->chown(vfsStream:: OWNER_USER_2 ); $vfsStreamDirectory->chown(vfsStream:: OWNER_ROOT ); $vfsStreamFile->chgrp(vfsStream:: GROUP_USER_2 ); $vfsStreamDirectory->chgrp(vfsStream:: GROUP_ROOT );

31. vfsStream:: OWNER_USER_1 // 1

33. vfsStream:: GROUP_USER_1 // 1

34. vfsStream:: GROUP_USER_2 // 2

36. chmod() , chown() , chgrp(), tempnam() doesn't work with streams

37. no support for fileatime() and filectime()

38. realpath() and touch() does not work with any other URLs than pure filenames

39. Smarty doesn't like it ;(

41. skips when vfsStream not installed

42. unified interface
