If you are using IntelliJ for test execution and debugging, but not for editing. Your other editor/IDE may be battling with IntelliJ for control over generated files (*.class) -- resulting in IntelliJ reporting that No tests were found (and maybe spurious build errors too).

In my case, Visual Studio Code seem to be having this effect (after recent updates to both tools).

The solution that I have found is to close Visual Studio Code and then clean rebuild the project with IntelliJ or from the command-line. In otherwords, my dual-IDE workflow no longer works -- so I have to edit in IntelliJ.
