Nevermind, I've spent some hours yesterday and then again today to add support for 'Test File' and 'Debug Test File' actions. Technically it will be possible to add 'Test Method' action in the future as well. Another step is to re-implement this support for Gradle projects too.
To make it even better the functionality is added to free version. I didn't want to spent extra time and create another barrier. Still it is my hope that some users can appreciate the result and go for subscription (or make a donation).
