Kotlin 1.5.0 - TestSuiteExecutionException testing function with "when" and enum about spek HOT 8 OPEN

Weird and interesting at the same time. Have you tried disabling the new IR backend compiler?

from spek.

@raniejade is the IR compiler just for targeting JS? I am using JVM

from spek.

@ryanelliott-wk There's an IR backend for JVM as well which was made the default in Kotlin 1.5

from spek.

I see the same exception with useIR=false

Here are my compiler options:

compileKotlin {
    kotlinOptions {
        useIR = false
    }
}

compileTestKotlin {
    kotlinOptions {
        // Needed for runBlocking test coroutine dispatcher
        freeCompilerArgs += "-Xuse-experimental=kotlin.Experimental"
        freeCompilerArgs += "-Xopt-in=kotlin.RequiresOptIn"
        useIR = false
    }
}

from spek.

I just run the test you provided with Kotlin 1.5.0 – works fine for me...

from spek.

Interesting thanks @ntoskrnl! Maybe some caching issues? Have you tried doing a clean build @ryanelliott-wk ?

from spek.

Thanks for trying it out @ntoskrnl!

@raniejade I'm still having the issue with a clean build. I'll try to do a more standalone reproduction - maybe there is another dependency somewhere in my project that is contributing to the issue.
