Can something like “Rule” be used in kotest? I need to set the MainCoroutineRule.

no, they're for junit, but you might not need it. What does main coroutine rule do ?

```@ExperimentalCoroutinesApi
class MainCoroutineRule(
    val testDispatcher: TestCoroutineDispatcher = TestCoroutineDispatcher()
) : TestWatcher() {

    override fun starting(description: Description?) {
        super.starting(description)
        Dispatchers.setMain(testDispatcher)
    }

    override fun finished(description: Description?) {
        super.finished(description)
        Dispatchers.resetMain()
        testDispatcher.cleanupTestCoroutines()
    }
}```


In kotest, all tests are coroutines, so you can just use withContext and set any dispatcher you want

```test("my test") {
  withContext(TestCoroutineDispatcher()) {
    ...
  }
}```

or if that doesn't work (I'm not sure what Dispatchers.setMain is), you could write a listener to do that easily

```class MainCoroutineListener(
    val testDispatcher: TestCoroutineDispatcher = TestCoroutineDispatcher()
) : TestListener() {

    override fun beforeTest(description: Description?) {
        Dispatchers.setMain(testDispatcher)
    }

    override fun afterTest(description: Description?) {
        Dispatchers.resetMain()
        testDispatcher.cleanupTestCoroutines()
    }
}```

Is this how to create a new testListener?

Is it possible to create a custom listener?

_class_ MyTestClass : FunSpec({
  listeners(TimerListener)
  _// tests here_
})

_class_ MyTestClass : FunSpec({
  listeners(MainCoroutineListener)
  _// tests here_
})

or if you want to register them at the global level, you can use project config
