Is there any way to define

@BeforeClass

/

@AfterClass

in multiplatform common tests? AFAICT these annotations are JVM-only at the moment 😞 I could add cleanup after each test, but that's a bit overkill, and may not work for every use case.

there's kotlin.test.BeforeClass/kotlin.test.AfterClass on native, but right, nothing for JS/common

Here's how I've hacked it https://github.com/mpetuska/monko/blob/master/test/src/commonMain/kotlin/BlockingTest.kt

@ephemient Ok, thanks, that's what I feared... 😭

@Before Old can easily be added to that class. @After might be more tricky

@BeforeTest

and

@AfterTest

are already supported out of the box on all platforms, though: https://kotlinlang.org/api/latest/kotlin.test/kotlin.test/-before-test/ https://kotlinlang.org/api/latest/kotlin.test/kotlin.test/-after-test/ So I already have this option without extra hack (which is what I'm doing now), but I wanted to have class-level hooks to avoid unnecessary work (I use these hooks to generate reports).

Hmm, can't recall why I've made my own. But I was aware of those already.

it looks like QUnit, Jasmine, Mocha, Jest, and Karma all support some form of beforeAll()/afterAll() (called before()/after() in some), so I feel like Kotlin's test adapter should be able to translate somehow… I don't know how to make that happen, though.

Yeah I have the same feeling. Since it's explicitly stated in the

BeforeClass

docs that it's not supported in common code, I don't think the Kotlin team just "forgot". There is likely some blocker they must have faced but I'd be interested in knowing what exactly.
