Simple but sometimes overlooked cause: ensure you don't have syntax or compilation errors.

If running a Karma test for JavaScript via your IDE, you may have a syntax error which doesn't appear when you run your tests. This leads to Karma issuing the message "no tests were found".

I ran it under WebStorm; the error appeared under the "Karma Server" tab, while the "No tests were found" message appeared under "Test Run" (both tabs under "Run" or "Debug" tool window).
