问题描述
我正在尝试检查是否使用OCMock调用了类方法。我从OCMock网站和其他答案中搜集了新的OCMock版本（2.1）增加了对存根类方法的支持。
I am trying to check if a class method is getting invoked using OCMock. I have gathered from OCMock website and other answers on SO that the new OCMock release (2.1) adds support for stubbing class methods.
我正在尝试这样做：
DetailViewController：
DetailViewController:
+(BOOL)getBoolVal
{
return YES;
}
测试案例：
-(void) testClassMethod
{
id detailMock = [OCMockObject mockForClass:[DetailViewController class]];
[[[detailMock stub] andReturnValue:OCMOCK_VALUE((BOOL){YES})] getBoolVal:nil];
}
测试正在运行并且也在成功但即使我返回NO也会成功来自 getBoolVal 中 DetailViewController 中的方法。在保持该方法的断点时，测试执行不会停止，表明该方法未被调用。
The test is running and also succeeding but it succeeds even if I return NO instead of YES from getBoolVal method in DetailViewController. On keeping a breakpoint on that method, the test execution does not stop indicating that the method is not called.
如何检查类方法？
推荐答案
也许我在这里遗漏了一些东西（我知道这有点旧），但你的班级签名是 +（BOOL）getBoolVal {return YES; } 并且在您的测试中，您在 getBoolVal上调用expect：nil
Maybe I'm missing something here (and I know this is a bit old), but your class signature is +(BOOL)getBoolVal { return YES; } and in your test, you're calling expect on getBoolVal:nil
那些不匹配，对吧？在那种情况下，你的班级模拟会说，哦，这不是我期望的签名，并试图将其传递给underyling类，我相信。请参阅。
Those don't match, right? In that case, your class mock will say, "Oh, that's not the signature I expect" and try to pass it on to the underyling class, I believe. See the forwardInvocationForClassObjectin the OCMock source.
至于为什么你得到NO（因为基础类也返回YES，这使得这个测试没有实际意义，但这是另一个问题），我不是百分百肯定，但也许这只是一个C-ism - '不确定的价值，无效，0（假/否）
As far as why you're getting NO (since the underlying class also returns YES, which makes this test kind of moot, but that's another issue), I'm not 100% sure, but maybe it's just a C-ism -- 'indeterminate value, void, 0 (false/NO)"
