Hi, does anyone have any hacks or tips to get kotest to work with amper? For me it’s reporting something like “no test classes found”

[Anton Prokhorov]

could you please share the project if it's possible?

(works on my machine :DDDDD) (c) TM

[joffrey]

Could you please describe how exactly you run things? Maybe share a reproducer project?

[joffrey]

Jinx 🙂

I found one problem, but maybe more (upd: link was wrong, now it's correct one)

I am also getting no test were discoverd error even though tests are there in shared/test folder

$ ./amper test 
...

    ERROR: JVM tests failed for module 'shared' with exit code 2 (no tests were discovered) (see errors above)

By the way, in amper, should a test run as part of a build/package or do we need to explicitly invoke it?

I believe you might be running into the common issue that the defaults of the JUnit Console launcher (which we're using) is to filter only test classes that start or end with Test or Tests. This is a bit confusing and we might change it. Could you please confirm whether your test classes were missing such suffix/prefix? Do you get the same issue if you rename your classes to add such suffixes/prefixes?

In Amper we decided that the build command was only for building (initially we even called it compile to avoid confusion with Gradle semantics). ./amper test will of course compile before testing.
So yes, you do need to call ./amper test if your goal is to run tests.

shared/test/test.kt

import kotlin.test.Test
import kotlin.test.assertTrue

class WorldTest {
  @Test
  fun doTest() {
    assertTrue(World().get().contains("World"))
  }
}

This is generated by the default multiplatform cli amper template.

The tests are running for native target

Strange. These JVM tests work for me locally:

(by the way, I'll remove these nasty warnings about expect/actual classes, sorry about this)

[joffrey]

Are you using any test filters (CLI options)? Or literally running just ./amper test?

[arve]

Problem seems to be gone now, amper does pick up the tests. I will do some more research.

I do notice that the green gutter arrows show up (via kotest plugin i suppose), but they don’t wok: «Nothing here»

The arrows work in gradle project, for running some specific test or suite.

[suresh]

@joffreyMy bad, i think it’s working as expected. The error was from testJvm, and I only have tests for shared/test. Sorry for the confusion.
