Use of "withEnvironment" extension function works when playing a spec class, but not an individual leaf

[zakhenry]

for example with the following spec file:

/* 1 ▷ */ class FTest: DescribeSpec({

/* 2 ▷ */    describe("f") {

/* 3 ▷ */        it("f") {

                     withEnvironment("FooKey", "BarValue") {
                         System.getenv("FooKey") shouldBe "BarValue" // System environment overridden!
                     }

                 }

             }

         })

if I play the line 1 the test passes, however if I play 2 or 3 the test fails with

Unable to make field private final java.util.Map java.util.Collections$UnmodifiableMap.m accessible: module java.base does not "opens java.util" to unnamed module @4f209819
java.lang.reflect.InaccessibleObjectException: Unable to make field private final java.util.Map java.util.Collections$UnmodifiableMap.m accessible: module java.base does not "opens java.util" to unnamed module @4f209819

Kotest 5.5.2 and plugin version 1.3.68-IC-2023.1. I do have the following lines in build.gradle.kts

tasks.withType<Test>().configureEach {
    jvmArgs("--add-opens=java.base/java.util=ALL-UNNAMED")
}

@zakhenry the Gradle configuration will only take effect when tests are invoked using Gradle.

When running an individual test, Kotest IntelliJ plugin will not invoke the test with Gradle, so the --add-opens is not applied.

Once https://github.com/kotest/kotest-intellij-plugin/issues/178 is fixed, you could configure IntelliJ to run tests with Gradle and this would work for individual tests as well.

Have you thought about using the kotest.properties setting ?

Ah yes this is a good solution thanks, doc ref for future reference: https://kotest.io/docs/intellij/intellij-properties.html

'withEnvironment' still doesn't work in kotest 5.5.5. I've opened the issue https://github.com/kotest/kotest/issues/4036

Could someone add an example what we need to put into kotest.properties to get withEnvironment {} working?
