PHPUnit 测试双抛出 PHPUnit_Framework_MockObject_BadMethodCallException

Question

我正在尝试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);
}

...但它会抛出 PHPUnit_Framework_MockObject_BadMethodCallException 异常，但不会抛出其他异常(例如原因)。如果我执行 echo get_class($auth); exit; 从我的应用程序中我可以看到它属于 Mock_QA_Auth_f4627b7b 类，因此至少它正在获取模拟实例。但是当我调用 isAuthenticated 方法时，它会抛出该异常。我做错了什么？

这是我看到的错误消息:

Answer 1

QA_Auth::isAuthenticated() 是静态方法，不能模拟静态方法。

Limitation: final, private, and static methods

Please note that final, private and static methods cannot be stubbed or mocked. They are ignored by PHPUnit's test double functionality and retain their original behaviour.

— Test Doubles

手册说测试替身“保留其原始行为”，但对于静态方法而言并非如此。有一个 open issue about it .另见 PHPUnit Mock Objects and Static Methods .
