I’m using the “js” plugin with the “nodejs” configuration, just to build a utility app. Things are mostly working, but one issue I’ve encountered is that I can’t write async tests — normally with Mocha/Jest etc a test can be written as an async function, or take a done parameter, but the JS produced by the Kotlin/JS compiler from inspecting the test sources seems to preclude that:

test('resolve_gradle', false, function () {
        var tmp$;
        tmp$ = new VersionResolversTest();
        tmp$.beforeTest();
        try {
          return tmp$.resolve_gradle();
        }finally {
          tmp$.afterTest();
        }
      });

(beforeTest and afterTest here were methods annotated with @BeforeTest and @AfterTest )
Is this output configurable in any way?

I’m seeing no one’s gotten back to you - the way the kotlin test package is set up, you can return promises from your test cases technically (I’ve been exploiting this in my own code), but last time i played with it, it didn’t work in before + after functions.

happy to chat about it if you still need help

That makes sense, actually, the return value from the test is passed up, so returning a promise should work. I think my eyes slipped over that last time I looked…

Ah, yes, if I make the test return a promise and delay for over 2 seconds, it gets caught by the timeout, so clearly it’s working. Just before/after aren’t, which is a shame.

Thanks for the reply 🙂 I’m just writing tests like this:

@Test
    fun some_async_test() = GlobalScope.promise {
        println("this is an async test")
        delay(1500L)
        println("it's finishing after a delay")
    }

Is that the same pattern you’ve got?

pretty much, with some sugar
