@Eneuman Thanks for your PR!

My in-depth review of this pull request is as follows:

This pull request looks good overall. It fixes some tests that had swaped the actual argument with the expected argument, and optimizes a test by using Assert.DoesNotContains instead of multiple checks. It also removes 4 warnings.

The changes look good. In the first change, the arguments in the Assert.Equal statement were swaped, so the change is correct. In the second change, the Assert.NotEqual statement was changed to Assert.DoesNotContain, which is more efficient and correct. In the third change, the arguments in the Assert.Equal statement were swaped, so the change is correct.

Overall, this pull request looks good and should be accepted.
