Hello! How would I apply a JUnit Rule with Spek?
Example:

internal class StatsViewModelSpek : Spek({
    describe("a StatsViewModel") {
        beforeEachTest {
            // Junit Rule to apply 
            InstantTaskExecutorRule()
        }
        context("") {
            val stats = Stats()
            on("create") {
                it("should initialize without problems") {
                    val statsViewModel = StatsViewModel(stats)
                }
            }
        }
    }
})

This returns java.lang.RuntimeException: Method getMainLooper in android.os.Looper not mocked, because I use LiveData inside that viewModel

So instead of calling InstantTaskExecutorRole() I added this

beforeEachTest {
            // Junit Rule to apply
            ArchTaskExecutor.getInstance().setDelegate(object : TaskExecutor() {
                override fun executeOnDiskIO(runnable: Runnable) {
                    runnable.run()
                }

                override fun isMainThread(): Boolean {
                    return true
                }

                override fun postToMainThread(runnable: Runnable) {
                    runnable.run()
                }
            })
        }

and that does the job

Also afterEachTest { ArchTaskExecutor.getInstance().setDelegate(null) } just to be doing the same thing as the rule
