Hey folks. I have a question loosely related to how things work with the Kotlin Multiplatform Plugin: I currently have this code:

val testResultsElements = configurations.consumable("testResultsElementsForJvmTest") {
    // This configuration mimics that defined by the "test-suite-base" plugin
    description = "Binary results obtained from running the 'jvmTest' suites."

    attributes.attribute(Category.CATEGORY_ATTRIBUTE, objects.named(Category.VERIFICATION))
    attributes.attribute(VerificationType.VERIFICATION_TYPE_ATTRIBUTE, objects.named(VerificationType.TEST_RESULTS))
    // FIXME how do we accommodate multiple JVM targets and their respective test suites?
    attributes.attribute(TestSuiteName.TEST_SUITE_NAME_ATTRIBUTE, objects.named("test"))

    val binaryDir = tasks.named<Test>("jvmTest").flatMap { it.binaryResultsDirectory }
    outgoing.artifact(binaryDir) {
        type = ArtifactTypeDefinition.DIRECTORY_TYPE
    }
}

I'm wondering what I would have to change if I had two source sets that produced JVM code, so I would have two "testResults" configurations. And how that would relate to the test result aggregation plugin since I would need to differentiate them in such a way that the aggregation plugin could pick each of them separately.

The test suite name attribute is what you use to choose

Odd. When I tried to add a dependency in the project that uses the aggregation plugin, it only accepted

test

. Perhaps I'm doing something wrong.

What do you mean with "it only accepted `test`"? What happened?

I got a

Mutation of attributes is not allowed

error when I try

dependencies {
  testReportAggregation(...) {
    attributes.attribute(TestSuiteName.TEST_SUITE_NAME_ATTRIBUTE, objects.named("jvmTest"))
  }
}

Not sure if I'm doing that correctly.

No, you only set the attribute on the producer. For consumption you do it like documented in the user guide

org.gradle.internal.component.resolution.failure.exception.VariantSelectionByAttributesException: The consumer was configured to find a component of category 'verification', as well as attribute 'org.gradle.testsuite.name' with value 'test', attribute 'org.gradle.verificationtype' with value 'test-results'

This is what I get when I have it as

jvmTest

in my producer. The error reads as if it accepts

test

and nothing else.

It accepts what you request

Right, but I need to aggregate reports for which it is

test

in some and

jvmTest

in others.

Nope

Oof. Smoke and mirrors with configurations it is, I suppose. That's kind of a "rename".

Nah, it's a copy or alias 😄
