Don't know Android, so could be completely wrong here.
This channel is for support of the https://github.com/kotest/kotest testing library, and not something that is built into the Android libraries.
If I'm correct, and this isn't related to the Kotest library, then a generic channel like #test or #android may be a better place to ask.
If I'm wrong, then one of the devs, or another user, will be along to help you.
No worries. Too many channels. And this tool used to be called Kotlintest. Lots of confusion because people thought this channel was for the kotlin-test that Jetbrains provides...
