Junit5 Testsuite With Selectclasses Not Working In Android Unit Test

i am trying to create a test suite for Unit test of android application, but it always fails with different kinds of configuration error, one among that is as follows, FAILURE: Bui

Solution 1:

I see you are using @RunWith(JUnitPlatform::class) which basically says "hey, please JUnit5, run my JUnit 4 tests!" but then you have used org.junit.jupiter.api.Test annotation, which tells the platform that those are JUnit5 tests.

So actually, there are no JUnit 4 tests to run.

I'd suggest you to drop the Suite at all and if you want test suites use nested classes. Or use Tag annotation to group tests.

By default, JUnit5 will run all @Test methods you have in the test src path. Check your gradle config for those.

Solution 2:

Are you using gradle to run your tests? Because I downloaded your branch, played a little bit to setup an environment without android studio (my personal computer has no dev environment installed) and I got this output on your JUnit 5 branch:

./gradlew appModules:factList:test --rerun-tasks

Maybe you need to delegate build actions to gradle (it is possible on IntelliJ, not sure on Android Studio) or clear your project settings or something like that.

Probably you are trying to use a Run Configuration that runs your suite, which is a JUnit4 Suite and expects JUnit4 tests but your tests are JUnit5 tests.
