如何捕获发送给模拟的参数？ [英] How to I capture an argument sent to a mock?

问题描述

有谁知道如何捕获发送到OCMock对象的参数？

Does anyone know how to capture an argument sent to an OCMock object?

id mock = [OCMockObject mockForClass:someClass]
NSObject* captureThisArgument;
[[mock expect] foo:<captureThisArgument>]

[mock foo:someThing]
GHAssertEquals[captured, someThing, nil];

如何验证foo的参数？我也很乐意在模拟定义中的一个块内完成它，但是如果我可以将对象拿出来以便我可以稍后断言它的特性就会很棒。

How do I go about validating the argument to foo? I'm happy to do it within a block in the mock definition too, but if I could get the object out so that I can assert on feature of it later that would be brilliant.

这可以用OCMock吗？

Is this possible with OCMock?

推荐答案

如果你想验证你的参数，也许你可以直接做到这一点用你的东西设置你的存根：

If you want to validate your parameter maybe you can do it directly while you are setting your stub with something like :

id mock = [OCMockObject mockForClass:someClass];
NSObject* captureThisArgument;
[[mock expect] foo:[OCMArg checkWithBlock:^(id value){ 
    // Capture argument here...
}]];
