Kotlin/JS 2.0.0-RC1 Incompatibilities (environmental variables not working, error output not printed)

[mgroth0]

Hello, aside from the lack of support for nested tests what is the current status for support of Kotlin/JS tests for Kotlin-2.0.0 RC1?

Here is my current experience in my real project.

First, these are some of the important JS configurations I have set:

• ecmaTarget: es5 (not es2015)
• variant: CommonJS (not ECMAScript)
• IR Compilation
• Mocha Test Task
• JS Target: Browser

And I am doing this with versions:

• Regular Kotest dependencies: 5.9.0.1440-SNAPSHOT
• Gradle plugin: 5.8.1 (I see no gradle plugin snapshot build)
• Setting kotestCompilerPluginVersion to 5.9.0.1440-SNAPSHOT

And my experience in my real project is the I see two issues, and unsure if they are related or not:

1. Error output is not printed. I just see

command '/Users/matthewgroth/.gradle/nodejs/node-v20.10.0-darwin-arm64/bin/node' exited with errors (exit code: 1)

Errors do not show in gradle output at all, even at the --info log level. I have to copy and paste the full test shell command to a terminal in order to see any errors.I saw a commit from 3 weeks ago that mentioned fixing log output: 2d62856But I am using the latest snapshot. I'm not sure if that commit was applied in the snapshot I am using?

2. when the kotest plugin is applied for some reason, environmental variables are no longer passed to tests.

(this property is broken: https://github.com/JetBrains/kotlin/blob/d19d5c38feb8cc88064235b322e3dc44d3cfc32f/[...]/org/jetbrains/kotlin/gradle/targets/js/testing/KotlinJsTest.kt)

Please let me know if I should split this into two different issues.

This is about a Node.js test, right? If so, the issue is #3329, which has been around for a while but will get fixed by #3954 once that is merged. I'll try to get this done by next weekend, so then there will be a snapshot you could use.

2. when the kotest plugin is applied for some reason, environmental variables are no longer passed to tests.

I have no idea. Are you expecting environment variables to be passed to JS in the browser? In any case, please open a separate issue and refer to relevant documentation.
