I've attached a zip that reproduces the issue along with a README.md + screenshot explaining the bug. Details copied here.
This repo demonstrates a bug in Android Studio. The Android Studion "Android Explorer" does not show test directories for combined flavors.

Please reference:

1. I have set up two flavor dimensions. "consumer" and "mockMode". Each has two flavors. These are consumer="developer|user", mockMode="official|simulated".
2. I have selected the "developerSimulatedDebug" variant.
3. I've checked the source sets that are available and want android tests that are only in the "developerSimulated" variant.
4. I created a non-test class called "Placeholder" in the "developerSimulated" source set to demonstrate that works.
5. I created "ExampleInstrumentedTest2" in the "androidTestDeveloperSimulated" source set but
6. It is not shown in the "Android Explorer" on the left. (This is the bug)
