When trying to review some code from a colleague, I first tried to run the available unit tests in Visual Studio. The tests were successfully discovered but when I tried to execute them, nothing happened. In the test output window I noticed the following message:
No test matches the given testcase filter
This error made me think that somewhere a testcase filter was set. But where?
I started searching inside the available settings and config files but I couldn’t find anything special. The error message mislead me, the problem was not related to any kind of testcase filter. It turned out that the problem was caused by the fact that the NUnit Test Adapter wasn’t installed.
I opened the Package Explorer and installed the NUnit3TestAdapter.
