“Test events were not received” when run tests using Intellij

Question

I have a Kotlin project and when I run my JUnit tests, I can\'t see tests execution result in IntelliJ and get this message instead:

test events were not

Answer 1

When trying to work out this problem for myself, I discovered JUnit 4 worked, but JUnit 5 reports "Tests were not received." Per petrikainulainen.net I found my solution.

Even though Gradle 4.6 (and obviously all newer versions) has a native support for JUnit 5, this support is not enabled by default. If we want to enable it, we have to ensure that the test task uses JUnit 5 instead of JUnit 4.

When I added the following code to Gradle, JUnit 5 worked.

test {
    useJUnitPlatform()
}
