Unable to run tests

[Tunous]

When I try to run any of the tests via Android Studio I get an error similar to the one below. Is there anything I have to do/install before being able to run tests?

I can see that as well. I'll try to have a fix soon. Surprisingly, it works from the command line...

Should be fixed on master now. Had to upgrade Mockito-Kotlin to the latest version.
