copied!<p>Your question is not very clear - but I assume you are asking how to use phpunit's mock objects to return a different value in different situations?</p> <p>PHPUnit's mock classes allow you specify a custom function (ie: a callback function/method) - which is practically unlimited in what it can do.</p> <p>In the below example, I created a mock IUrlStorage class that will return the next url in its storage each time it is called.</p> <pre><code>public function setUp() { parent::setUp(); $this->fixture = new UrlDisplayer(); //change this to however you create your object //Create a list of expected URLs for testing across all test cases $this->expectedUrls = array( 'key1' => 'http://www.example.com/url1/' , 'key2' => 'http://www.example.net/url2/' , 'key3' => 'http://www.example.com/url3/' ); } public function testUrlDisplayerDisplaysLatestUrls { //Init $mockStorage = $this->getMock('IUrlStorage'); $mockStorage->expects($this->any()) ->method('getUrl') ->will( $this->returnCallback(array($this, 'mockgetUrl')) ); reset($this->expectedUrls); //reset array before testing //Actual Tests $this->assertGreaterThan(0, count($this->expectedUrls)); foreach ( $this->expectedUrls as $key => $expected ) { $actual = $this->fixture->displayUrl($key); $this->assertEquals($expected, $actual); } } public function mockGetUrl($name) { $value = current($this->expectedUrls); next($this->expectedUrls); //Return null instead of false when end of array is reached return ($value === false) ? null : $value; } </code></pre> <hr> <p>Alternatively, sometimes it is easier to simply create a real class that mocks up the necessary functionality. This is especially easy with well defined and small interfaces.</p> <p>In this specific case, I would suggest using the below class instead:</p> <pre><code>class MockStorage implements IUrlStorage { protected $urls = array(); public function addUrl($name, $url) { $this->urls[$name] = $url; } public function getUrl($name) { if ( isset($this->urls[$name]) ) { return $this->urls[$name]; } return null; } } ?> </code></pre> <p>Then in your unit test class you simply instantiate your fixture like below:</p> <pre><code>public function setUp() { $mockStorage = new MockStorage(); //Add as many expected URLs you want to test for $mockStorage->addUrl('name1', 'http://example.com'); //etc... $this->fixture = new UrlDisplayer($mockStorage); } </code></pre>
