I'm having trouble running common tests from IDEA. They run fine from the command line but whenever I try to run them from IDEA I get this:

Execution failed for task ':myProject:jvmTest'.
> No tests found for given includes: [MyClass](filter.includeTestsMatching)

This is the button I'm pressing
What am I doing wrong?

[robstoll]

maybe https://youtrack.jetbrains.com/issue/KT-26792?

[addamsson]

this is not Junit 5 but simple kotlin test common tests

[addamsson]

import kotlin.test.BeforeTest
import kotlin.test.Test
import kotlin.test.assertEquals
import kotlin.test.assertTrue

Hey @addamsson,
Is it possible you’re missing the following in your build.gradle?

test {
    useJUnitPlatform()
}

I ran into the same issue a while ago.

[addamsson]

I'm gonna take a look

[addamsson]

you are right!!!!!!

[addamsson]

thanks!

[addamsson]

although

[addamsson]

this is a multiplatform project

[addamsson]

where do I put this?

[simon.vergauwen]

Hmm that I am not 100% sure of. I’d think the equivalent subProjects { ... } in your top build.gradle https://github.com/arrow-kt/arrow/blob/master/build.gradle#L97

[addamsson]

thanks

[addamsson]

didn't help as this is not a multiplatform project 😞

[addamsson]

this only happens with MPPs

[simon.vergauwen]

I was afraid of that 😞

[simon.vergauwen]

Damn, KotlinTest 3.0 works MPP right?
I know @sam planned a big refactor for 4.0, and they working on it.

[addamsson]

if i run it from the CLI it is fine

[addamsson]

this is only a problem within IDEA

[simon.vergauwen]

Oh maybe you can fix that with this

[addamsson]

I tried running the tests using idea instead of gradle, but that didn't change anything

[simon.vergauwen]

I once ran into some weird issues, and finally discovered this was not on Gradle (Default) but on IntelliJ IDEA and that was causing me issues.

Since then I’ve only worked with Gradle (Default) and never ran into such weird things again. I never manually changed away from default tho so not sure how that happened.

What if you run tests using Gradle instead?

[addamsson]

it was the original setting

[addamsson]

I just tried IDEA

[simon.vergauwen]

Oh so probably not that then 😞

[addamsson]

thanks anyway 🙂

[addamsson]

oh

[addamsson]

I tried running Gradle from within IDEA and now it works
