MockManager.Verify not working?

I'm not sure why you're having this issue - I need to further investigate this.

Is there a reason you're not using AAA API?

[TestMethod]
public void TestPropertyUsingAAA()
{
    var t = Isolate.Fake.Instance<Test>();

    Isolate.WhenCalled(() => t.TestProperty).WillReturn("test");

    Isolate.Verify.WasCalledWithAnyArguments(() => t.TestProperty);
}

Seems like a better way to write the test you've posted

hi,

ExpectGetAlways semantics means that it will expect zero or more calls to it.
which mens that not having any calls will not fail the verify.

You can either use the AAA syntax as Dror has suggested,
or if you want to code something in the spirit of expect 1 or more calls
try adding a regular ExpectGet statement just before the ExpectGetAlways

I figured that out, but nowhere in the documentation is that mentioned, and the name indicates you are setting up an expectation. It is just confusing the way it is named.

The reason this isn't using AAA is because this is one of hundreds of unit tests that were written prior to AAA being supported, and I am not interested in going back and rewriting them.
