Getting Different Results: Run Single vs. Run All

0 votes
I have a unit test that does an ExpectAndThrow so that I can unit test my exception handling.

When I execute the test by itself, it passes - the exception is thrown, and the enterprise library logging writes the error log to the database.

When I execute the test with all of my other unit tests (or just one other test, for that matter), the exception is thrown - but I get an ExceptionHandling exception (object reference not set to an instance of an object).

I do not understand why I am getting different behavior simply based on whether or not the test is executed by itself vs. with others.

Has anyone else encountered this issue?

Hi,
This can happen when a mock from a previous test is affecting your test.
To make sure this doesn't happen use MockManager.ClearAll(); in your TearDown method.
:idea: You can also analysis this case using the TypeMock Tracer Utility.
If this doesn't help please tell us and we will analysis the TypeMock logs.
