Junit 5 not detected

so, i'm trying to create a unit testing with Junit 5, but for some reason the test event were not received. I already removed Junit 4 from gradle dependencies.

import org.junit.jupiter.api.Assertions
import org.junit.jupiter.api.BeforeEach
import org.junit.jupiter.api.Test

class TestTest {

    @BeforeEach
    fun setup() {
        println("Setup")
    }

    @Test
    fun testFoo() {
        Assertions.assertTrue(true)
    }
}

and my gradle dependencies for junit5:

 testImplementation 'org.junit.jupiter:junit-jupiter-api:5.9.3'
 testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.9.3'
 testImplementation 'org.junit.jupiter:junit-jupiter-params:5.9.3'
Solution

  • I've run into this kind of behavior a few times and in my case, I missed specifying useJunitPlatform() for all test tasks (also see here) like this (I suppose you're using groovy gradle DSL):

    tasks.named('test', Test) {
    useJUnitPlatform()
}

    This is just an educated guess - to be sure, you'd need to post more of your build.gradle-file, so I could reproduce your setup.
