Running unit tests from the left gutter breaks debugging unit test

Steps to Reproduce

Running the tests from the left gutter breaks. The only way to run them again is restarting IntelliJ.

1. Set a break point in the test case
2. Run a unit test from the left gutter run or debug button. (don’t stop debugging process)
3. Then click on debug button in the top menu, right of the device selection. (try to start process again)

What I think is happening, when trying to start the debugging process again before it was completed while paused on a break point creates an inconsistent state. I’ve noticed an exception thrown in IDE log as well but I can’t replicate it again. What I’m finding my problem is, I forget to resume past the break point so the unit test finishes. And then I try to start it over while it’s paused, the second process doesn’t restart. Once I terminate the process, I can no longer launch another debugging instance from the left gutter button.

After a third launch of debugging I can no longer run the individual unit test from here.

How I start it the second time, and it breaks IDE.

How I ran it the first time.

Just FYI, I was not able to reproduce the problem. But I can see why https://github.com/flutter/flutter-intellij/issues/1622 happens and will fix it.

I’m unable to reproduce on tip of head either. Hopefully we should be good with the next release. Optimistically closing.
