如何使用OCMock来验证方法从未被调用？ [英] How can I use OCMock to verify that a method is never called?

问题描述

在我的一天工作，我被宠坏了 Mockito的 never（）验证，可以确认模拟方法从未被调用。

At my day job I've been spoiled with Mockito's never() verification, which can confirm that a mock method is never called.

有没有办法使用Objective-C和OCMock完成同样的事情？我一直在使用下面的代码，这是工作，但它感觉像一个黑客。我希望有更好的方法...

Is there some way to accomplish the same thing using Objective-C and OCMock? I've been using the code below, which works but it feels like a hack. I'm hoping there's a better way...

- (void)testSomeMethodIsNeverCalled {
    id mock = [OCMockObject mockForClass:[MyObject class]];
    [[[mock stub] andCall:@selector(fail) onObject:self] forbiddenMethod];

    // more test things here, which hopefully
    // never call [mock forbiddenMethod]...
}

- (void)fail {
    STFail(@"This method is forbidden!");
}

推荐答案

自OCMock r69以来，可以拒绝方法调用 http://svn.mulle-kybernetik.com/OCMock/trunk/ Source / Changes.txt

Since r69 of OCMock, it's possible to reject a method call http://svn.mulle-kybernetik.com/OCMock/trunk/Source/Changes.txt

Nice mocks / failing fast当一个
方法被调用一个mock对象
没有设置与期望
或stub mock对象将引发一个
异常。通过创建一个漂亮模拟，可以关闭这个失败模式：

Nice mocks / failing fast When a method is called on a mock object that has not been set up with either expect or stub the mock object will raise an exception. This fail-fast mode can be turned off by creating a "nice" mock:

id mock = [OCMockObject niceMockForClass:[SomeClass class]]

虽然好的mock会忽略
所有意想不到的方法可能
禁止具体方法：

While nice mocks will simply ignore all unexpected methods it is possible to disallow specific methods:

[[mock reject] someMethod]

请注意，在故障快速模式下，如果忽略
异常，将会验证
rethrown称为。这个
可以确保可以检测到
不需要的来自
通知等的调用。

Note that in fail-fast mode, if the exception is ignored, it will be rethrown when verify is called. This makes it possible to ensure that unwanted invocations from notifications etc. can be detected.
