I'm getting a really odd phenomenon and I'm wondering if anyone else has experienced similar. I have a solution that contains 2 test projects. In total there are 141 tests currently running in it. Everything's fine.
I add one more test (and it doesn't matter which test project I add it to) and suddenly 8 other tests fail. The reasons for the failure are all because a file the test relied on failed to copy to the TestResults/../Out directory so wan't found by the test. I've checked the settings for these files and they should copy - in fact they did copy successfully before I added that 142nd test. I can rem the 142nd test back out again and all the oither tests will immediately pass.
What the...?
Has anyone come across this before? Google searches aren't finding me anything so far but I'm still trawling.
