There is a problem with running tests in Android studio: the test runner terminates after several tests (2-7) and message from above seems related.

Running tests from command line works:

./gradlew connectedAndroidTest --stacktrace --debug
...
Total tests 34, passed 34

From reactions here it may be an emulator/local only issue.

Here's the line in the Android source where it's thrown.
