<@U0L8Y9QLV>: `Method getMainLooper in android.os.Looper not mocked.` means that you’re trying to use class (in particular `Looper`) from Android SDK during jvm tests, Android Gradle Plugin creates `mocked` jar of Android SDK classes without implementation.

It’s not related to Spek and there are several solutions: 

* Don’t touch Android SDK classes in jvm tests
* Use Robolectric
* Write test as instrumentation test to run it on device/emulator instead of jvm
