I recently upgraded to version 2.0 and was able to run my Unit tests with coverage option from the Run Menu. Today, all of a sudden, I just kept getting the "Terminated" message when running the Unit tests with or without coverage.
If I click on the Left hand side "Run failed tests" or "Run Tests" from the Run Window, the tests run but when invoking the "Run TestClassName" or "Run TestClassName with Coverage" option from the Top Menu, the output window simply shows "Testing started at ... Using connection... " and then the test terminates.
I can confirm that nothing is wrong with my code because if I run the tests for the same from the Developer Console, they run just fine.
I have attached screenshot for the same.
I tried to regenerate the Offline Symbol table, etc. but the problem still remains. I wonder if this is a bug.
