So I've upgraded Resharper to version 10 (on VS2015), and now Unit Tests don't show output anymore in all our solutions:
This is very annoying because I want to see the reason why a test fails. The workaround for now is to use the new "Stack trace explorer", where the result is visible.
Oddly enough, when I create a brand new solution and write a simple test, the output window still works as it did!
Any ideas? Could this be a configuration issue?
