Move tests to correct folder

[lenguyenthanh]

I think we moved this test file into a wrong folder, so it stops running ( that why we thought it passes). But it is actually still failed.

Damn, that's too bad :(
Good we have a failing test now, hopefully we can fix it easily.

Moving to Kotlin 1.6.0 fixes the issue for me. I'm also going to attempt to use the workaround, since this is internal anyway.

@lenguyenthanh this is the fix following the tickets on the trackers.

@Serializable(with = ReferencedSerializer::class)
public open class Referenced<out A> internal constructor() {
  public data class Ref(public val value: Reference) : Referenced<Nothing>()
  public data class Other<A>(val value: A) : Referenced<A>()

  public fun <B> map(f: (A) -> B): Referenced<B> =
    when (this) {
      is Other -> Other(f(value))
      is Ref -> this
      else -> TODO("Impossible.")
    }
}

Test locally, and in downstream project and it fixes the issue for me.
I can add/push this fix on your branch later if you like so we can see this test pass.

[lenguyenthanh]

Great thanks @nomisRev ! I will try it local and push it to this branch.

[lenguyenthanh]

It worked locally, and open-api module is also working now for the first time 🎉

[nomisRev]

According to YouTrack this should be fixed in Kotlin 1.6.20, which is currently in M1.
So perhaps we should wait a bit to merge this PR. Hopefully in the next week we can introduce alpha releases like in Arrow, and maybe Kotlin 1.6.20 will be released by then.

Off-topic

@lenguyenthanh Are you depending on the SNAPSHOT? I also found they have an incorrect name.

"io.arrow-kt:ktor-server:0.1.2-SNAPSHOT"
"io.arrow-kt:openapi-docs:0.1.2-SNAPSHOT"

instead of

"io.arrow-kt:arrow-endpoint-ktor-server:0.1.2-SNAPSHOT"
"io.arrow-kt:arrow-endpoint-openapi-docs:0.1.2-SNAPSHOT"

Thanks for reporting and helping looking into this @lenguyenthanh ❤️

[lenguyenthanh]

Yeah, I agree with your approach, no need to rush to merge this PR.

I'm still using my Jitpack version. But I will try to use the snapshot version soon. Thanks for the head up, @nomisRev !
