I have around 700 tests and they all work except 1. Outside TeamCity the test work. I can do the test on the same machine of Team City and it works but not when Team City execute the test.
The test use a singleton (static instance), do you test are done in parallel?
Where can I get some information to find out why this unit test fail in TeamCity but not in NUnit directly (When I use ReSharper inside the IDE the test works too)?
