Expected nil, but was nil

[pikaboo]

How does this even happen?

Here is code to reproduce:

        _scriptManager = OCMPartialMock([ScriptsManager manager]);

        OCMStub([_scriptManager cachedData]).andReturn(nilValue());
        id expected = nilValue();
        id actual = [_scriptManager cachedData];
        assertThat(actual, equalTo(expected));

code from the library:

- (BOOL)matches:(id)item
{
    if (item == nil)
        return self.expectedValue == nil;
    return [item isEqual:self.expectedValue];
}

item == nil returns false

please see stackoverflow post below.

What is the question? Is there an OCMockito issue?

The question is: why is nil != nil ?

Your example shows OCMock, not OCMockito. Do you have an OCMockito question?
