Hi! Do you know if there is a way to programatically declare test cases with Kotlin/Native? For example, to create a for loop that creates multiple tests.

I've done that before for Kotlin/JVM by declaring a JUnit5 @TestFactory , and with Kotlin/JS by using dynamic to access the test list, but I have no idea how to do that with Kotlin/Native.

+1 not exactly the same but having parameterized KMP tests would be handy

[kevin.cianfarini]

I do a poor-mans parameterized test.

@Test fun theTest() { 
  (0..10).forEach { i ->
    parameterized(i)
  }
}

private fun parameterized(i: Int) {
  assertEquals(...)
}

@kevin.cianfarini I thought about this, but I'm going to use it to declare all tests…

[mbonnin]

@kevin.cianfarini works but loses some cool features like actually see the failing test in the report and most importantly running only one test with --tests

@mbonnin please upvote https://youtrack.jetbrains.com/issue/KT-46899

Ha I was going to suggest this 😄

[CLOVIS]

I have an in-house test framework that uses this for JVM and JS, I'm trying to make it into a standalone library with support for all platforms, but it will probably require hitting some Kotlin/Native internals and I don't know them

[CLOVIS]

Also, welcome back to this topic @Adam S 🙂 I'd greatly appreciate some magic like you found last time 😇

[Adam S]

I would try taking a look through the Kotest sources

[Adam S]

haha I'd like to find some magic too

[Adam S]

maybe use runTest {}? https://github.com/kotest/kotest/blob/master/kotest-framework/kotest-framework-engine/src/desktopMain/kotlin/io/kotest/engine/test/interceptors/TestCoroutineInterceptor.kt

[CLOVIS]

I'm a bit wary of looking through Kotest sources. Last time I tried to use them, Kotest just wasn't able to run JS tests (that's why I started making my own lib in the first place).

[CLOVIS]

I guess it was probably fixed since? But well

[Adam S]

yeah, Kotest had issues with nested Kotlin/JS tests, and probably still does, but the Native tests work fine

[Edoardo Luppi]

Yes Kotest still doesn't work correctly with JS in some cases, and it doesn't report failures correctly, that's why I'm not using it yet

[Edoardo Luppi]

Plus let's be honest, the fact you can't run common tests from the gutter is THE blocker IMO. Too handy
