Can I use JUnit5 Extensions with KoTest? If yes, how? Just adding the annotation for an Extension does not seem to execute it for me.

No, we have a wrapper but it's not very well tested.

Thanks for the quick reply. Is there another way to reuse code which is used in multiple test classes? The extension I am using is described in this blog post:

Kotest is just Kotlin so you have way more options to sharing code.

Extensions have the benefit that you can group setup and teardown code together and than apply them together. When I offer common code I would have to make sure to use the correct setup and teardown method manually in my tests. But maybe it is possible to create a pattern where you call external

berfore {} / after {}

blocks. I will tinker a bit 🙂

Got it. So what you might wanna do in Kotest is create a TestListener.

class/object Foo : TestListener {
  override fun beforeTest ... // set up
  override fun afterTest ... // tear down
}

Then you can add that to whatever tests you want.

class MyTest : FunSpec({
   listener(Foo())
   test("....) { }
})

Yes, perfect! Thanks 🙂

Cool, feel free to hit me up if you have anymore questions

specifically for LiveData, I wrote this listener and use it on a daily basis. Not sure why I didn't ship it to Kotest yet, but it works for my usecase

Haha that looks exactyl like the code I ended up with. I did add super calls because the IDE generated them for me. Not sure if needed though.
