For some unknown reason my pycharm has stopped successfully running unittests. Before I could simply right click a file of tests and hit Debug unittests in.. 
or in the file itself call for debugging on the TestCase subclass itself or on any test_ method thereof.  Now it just finishes immediately with nothing and creates an artifact in configurations that seems to be treating the unitest file as a simple python file.   If I delete that I sometimes get in a weird state where it fails a bunch of assertions immediately and tries to user my path to the file as a module somehow by the error it puts out.
I don't understand.  I have used pycharm for years and never seen this problem previously. 
Looks to be the 2019.2 version running on Ubuntu.  Did something change?
Ah ha! The project having the problem was opened via a soft link directory.  When I opened the same thing using the direct directory the problem disappeared.  Bizarre.
