"No tests found" error in a module that has no tests

Issue

I got a "No tests found" error for a specific module that has no instrumented tests (only JUnit tests) when running gradlew connectedAndroidTest in the pipeline. It's a bad thing because the app has other modules that have instrumented tests that don't run because the Gradle task fails.

I've tried removing androidTest dependencies and testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" but the problem is still happening.

Solution

Deleting androidTest directory solved the problem (the folder had no classes but had a .gitkeep file).

Apparently, it fails when the folder exists but has no tests in it.
