Hi all, I’m running into some challenges while trying to create integration tests using Gradle Kotlin DSL. I already just posted a question on StackOverflow. But I hope someone here can help me out with this one. https://stackoverflow.com/questions/52904603/integration-tests-with-gradle-kotlin-dsl

[Nikky]

as for sourcesets:

kotlin {
     sourceSets.maybeCreate("main").kotlin.apply {
                    srcDir(rootDir.resolve("something"))
                    srcDir(config.getGeneratedSrc)
                }
}

this is how i do it

[Nikky]

i am pretty sure for something to be recognized as test source you will have to add them to "test"

[Nikky]

and that guide sets up

compileClasspath += main.output + test.output
runtimeClasspath += main.output + test.output

for java, i think will want to do something similar

[Johan Vergeer]

@Nikky I’m confused here. I have a Kotlin project, with no Java sources, but I should still use java config?

[Nikky]

no, but you still need to depend on the output of test if you put your code into a differently named sourceSet
as i said.. something similar

[Johan Vergeer]

@Nikky Based on your first snipped, I created this

kotlin {
    sourceSets {
        maybeCreate("integrationTest").kotlin.apply {
            srcDir("src/testIntegration/kotlin")
        }
        maybeCreate("integrationTest").resources.apply {
            srcDir("src/testIntegration/resources")
        }
}

[Johan Vergeer]

Where would you put

compileClasspath += main.output + test.output
runtimeClasspath += main.output + test.output

There’s some existing documentation around this. Adding an integration test source set at https://docs.gradle.org/release-nightly/userguide/organizing_gradle_projects.html#sec:separate_test_type_source_files
Configuring a source set convention at https://docs.gradle.org/release-nightly/userguide/groovy_plugin.html#sec:changing_groovy_project_layout
It’s respectively for java and groovy, but the same pattern applies to configure the kotlin source set convention

@eskatos @Nikky Thanks for your help so far. This is the code I have so far:

kotlin
sourceSets.create("integrationTest") {
    java.srcDir("src/integrationTest/kotlin")
    resources.srcDir("src/integrationTest/resources")
    compileClasspath += sourceSets["main"].output + configurations["testRuntimeClasspath"]
    runtimeClasspath += output + compileClasspath + sourceSets["test"].runtimeClasspath
}

task<Test>("integrationTest") {
    description = "Runs the integration tests"
    group = "verification"
    testClassesDirs = sourceSets["integrationTest"].output.classesDirs
    classpath = sourceSets["integrationTest"].runtimeClasspath
//    mustRunAfter(tasks["test"])
}

I took the code snippet from the Gradle website Paul showed me (I did have to upgrade to Gradle 4.10.2 though, and changed some things

Since I have kotlin code the sources are located in src/main/kotlin and src/integrationTest/kotlin

I also added sourceSets["test"].runtimeClasspath to the runtimeClassPath.

[Johan Vergeer]

Right now everything compiles, but tests are not run when running the integrationTest task

[eskatos]

you should set the src/integrationTest/kotlin src dir to the kotlin convention of the source set instead of on java

[Johan Vergeer]

I tried this with kotlin.srcDir("..."), but that didn’t work

[eskatos]

see the second link I posted above

[eskatos]

you need the KotlinSourceSet convention of your integrationTest source set

[Johan Vergeer]

My bad. I’ll have a look

[Johan Vergeer]

kotlin
sourceSets {
    create("integrationTest") {
        withConvention(KotlinSourceSet::class) {
            kotlin.srcDir("src/integrationTest/kotlin")
            resources.srcDir("src/integrationTest/resources")
            compileClasspath += sourceSets["main"].output + configurations["testRuntimeClasspath"]
            runtimeClasspath += output + compileClasspath + sourceSets["test"].runtimeClasspath
        }
    }
}

[Johan Vergeer]

That worked

[Johan Vergeer]

The tests still did not run, until I changed the @Test annotation import from import org.junit.jupiter.api.Test to

[Johan Vergeer]

org.junit.Test

[Johan Vergeer]

But I think I know how to solve that

[eskatos]

👍

[Johan Vergeer]

task<Test>("integrationTest") {
    description = "Runs the integration tests"
    group = "verification"
    testClassesDirs = sourceSets["integrationTest"].output.classesDirs
    classpath = sourceSets["integrationTest"].runtimeClasspath
    mustRunAfter(tasks["test"])
    useJUnitPlatform()
}

[Johan Vergeer]

Just add useJunitPlatform()

[Johan Vergeer]

I’ll answer my own question to SO

[Johan Vergeer]

Would you like me to mention you guys?

I don’t mind not to be mentioned 🙂
