How to run unit tests located inside a android module?

Question

[Note from the future, 2021, added at the bottom - they shortened the answer]

Below i have a project with the above structure.

I can happily run uni tests fine inside the app module but unit tests found on the lib module doesn't get run unless i manually right click DummyDataTest.java inside the lib module and click run unit test inside Android studio.

Is there a way to automatically run unit tests located in my lib module through command line?

The existing command line ./gradlew testDebug only runs the unit tests located inside the app module.

Thanks in advance

Yes, use ./gradlew lib:testDebugUnitTest to run tests from lib module.
