An Android question, not Kotlin specific: What do I use to be able to write non-UI tests that run on JVM? I don’t want to have to create an activity like Roboelectric examples suggest. I don’t want a UI test — I just don’t want to have to mock platform dependencies.

You can use the androidUnitTest source set. Code there runs on your local machine.

1. :not-kotlin: (see the channel description) 2. Landry's answer only applies if you're using Kotlin Multiplatform. if you're not, this is described in the usual Android documentation.
