Question

我试图创建一个模拟对象，并在测试时在我的Zend框架应用程序中使用它：

public function testAskQuestionRouteWithLoggedIn()
{
    // get the mock auth object, and update the registry
    $auth = $this->getMockBuilder('QA_Auth')
        ->disableOriginalConstructor()
        ->getMock();

    // mock methods, and return values
    $auth->method('isAuthenticated')
        ->will( $this->returnValue( true ) );

    // update the registry
    $auth = Zend_Registry::set('Auth', $auth);

    // now preform the test as a logged in user
    $this->dispatch('/ask');
    $this->assertController('questions');
    $this->assertAction('new');

    // // // check the page contains a question form
    $this->assertQueryCount('form#questionForm', 1);
}

...但是它抛出了一个PHPUnit_Framework_MockObject_BadMethodCallException异常，但实际上并没有多少（例如原因）。如果我在我的应用程序中执行echo get_class($auth); exit;，我可以看到它是Mock_QA_Auth_f4627b7b类，所以至少它已经获取了模拟实例。但是当我调用isAuthenticated方法时，它会抛出异常。我做错了什么？

以下是我看到的错误消息：

Answer 1

QA_Auth::isAuthenticated()是一种静态方法，静态方法无法模拟。

限制：最终，私有和静态方法

请注意，无法对最终，私有和静态方法进行存根或模拟。它们被PHPUnit的测试双重功能忽略，并保留其原始行为。

- Test Doubles

本手册说，测试会使双倍＆＃34;保留其原始行为＆＃34;，但静态方法并非如此。有一个open issue about it。另请参阅PHPUnit Mock Objects and Static Methods。

PHPUnit测试double抛出PHPUnit_Framework_MockObject_BadMethodCallException
