Overwriting Expectations


recently came across the problem that I cannot overwrite my expectations:
        public void Test()
            var coordiante = Mock.Interface<ICoordinate>();
            Expect.PropertyGet(() => coordiante.X).Returns(0);
            Expect.PropertyGet(() => coordiante.X).Returns(1);

            Assert.AreEqual(1,coordiante.X); //fails because it returns 0
I need to test a algorithm, that depend on a object with multiple properties. For most of the test cases the properties are the same, so I set them up in the SetUp method. Within a test, I only want to adjust same properties needed. So I need to overwrite the Returns() I set up in the SetUp method.

I can simply move the initialization to the test, but my test became more verbose and the SetUp method useless.

Default expectations are matched in top down order as specified, so the call will always match the first PropertyGet of X in this case.

But you should be able to call Expect.WithHigherPrecedence.PropertyGet(() => coordiante.X).Returns(1); to put it on top of the "match list"
