I try to split the tests into unit tests and integration tests in my project(Kotlin, and Gradle Kotlin DSL), I added the following to ``build.gradle.kts`

val integrationTest = task<Test>("integrationTest") {
    description = "Runs integration tests."
    group = "verification"

//    testClassesDirs = sourceSets["intTest"].output.classesDirs
//    classpath = sourceSets["intTest"].runtimeClasspath
//    shouldRunAfter("test")

    useJUnitPlatform{
        filter {
            include("**/*IT.class")
        }
    }
}

tasks.check{
    dependsOn(integrationTest)
}

I have modified the integration test classes with a

IT

postfix. I have used

includes(**/*IT.class)

or

includeTestsMatching("*IT")

, it does not work when run

./gradlew clean intergrationTest

. All tests are run as before. Any suggestion here?

Nesting

filter

in

useJUnitPlatform

does not make much sense, that is just visual clutter as

filter

is a method on the

Test

task directly. Nesting

include

in

filter

does not make much sense, that is just visual clutter as

include

is a method on the

Test

task directly. So what you shows is the same as

useJUnitPlatform()
include("**/*IT.class")

Both the options you showed should imho work though. Can you maybe knit an MCVE that demoes the problem? Btw. you should not use

task("...")

as that is an eager api and not leveraging task-configuration avoidance. You can easily see this from the return type being the concrete task and not some provider.

@Vampire Thanks, use

tasks.register

instead. But the filter in integrationTest still does not work as expected, it still includes all tests in the

integrationTest

task, although I have moved the filter out of

useJunitPlatform

.
