Is there any way to define `@BeforeClass` / `@AfterClass` in multiplatform common tests? AFAICT these annotations are JVM-only at the moment :disappointed:
I could add cleanup after each test, but that's a bit overkill, and may not work for every use case.

there's <https://kotlinlang.org/api/latest/kotlin.test/kotlin.test/-before-class/|kotlin.test.BeforeClass>/<https://kotlinlang.org/api/latest/kotlin.test/kotlin.test/-after-class/|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|https://github.com/mpetuska/monko/blob/master/test/src/commonMain/kotlin/BlockingTest.kt>

And usage <https://github.com/mpetuska/monko/blob/master/lib/monko-core/src/commonTest/kotlin/MonkoClientTest.kt|https://github.com/mpetuska/monko/blob/master/lib/monko-core/src/commonTest/kotlin/MonkoClientTest.kt>

<@UJQB4DJF7> Ok, thanks, that's what I feared... :sob:

<@UL1A5BA2X> this is `@Before` /`@After` behaviour, where setup/cleanup is executed for each test. I'm looking for a single setup/cleanup for all tests.

<@U01SVFM9Y1W> can easily be added to that class. @After might be more tricky

But in most cases beforeEach and afterEach are good alternatives to before and after if you don't mind losing a bit of performance

`@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.

I haven't found any open issue in YouTrack regarding this, btw. Will probably open one for tracking
