Defect Description

Describe the defect

When a user runs:

./run_tests -j 12

It creates a minimum number of 110 files and directories that Git shows as untracked files.

What did you expect to see happen?

Running the tests should not change the state of the repository.

What did you see instead?

I see that a bunch of files and directories were created.

Do you have a suggested fix for the development team?

Improve .gitignore file or provide a 'clean-up' method to the testing interface.
