objective-c - 我如何使用 OCMock 来验证一个方法从未被调用过？

Question

在我的日常工作中，我被 Mockito's never() verification 宠坏了，这可以确认从未调用模拟方法。

有没有什么方法可以使用 Objective-C 和 OCMock 来完成同样的事情？我一直在使用下面的代码，它可以工作，但感觉像是 hack。我希望有更好的方法...

- (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!");
}

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

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]]

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

[[mock reject] someMethod]

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.
