Unit tests are missing in app/java

[Manue26]

I'd like to run the unit tests to understand their process. I'm using Android Studio However, in the file app/java, there is no file no.nordicsemi.android.nrftoolbox (Test) only a file no.nordicsemi.android.nrftoolbox (androidTest) in which a package "android.test.ApplicationTestCase;" is missing and therefore cannot be run. Can you fix this issue please, so I can test the unit tests?
Thank you very much
