有没有其他人遇到过这个问题？有关如何解决此问题的任何建议？

Answer 1

Workarounds for now:

1. Execute all tests in package or All unit tests

2. Open test configuration and re-select class and method explicitly from dialogs after saving no issues with test run.

3. Install latest beta version from Android Studio Canary channel. Bug already fixed there and no new blockers found
