This change doesn't really make sense.

The entrypoint for these test cases is meant to be the bash script which if given an empty folder for configs, will not run anyway.

It would make more sense to have Brian make that clear in a readme as he's working on an update and setting a default config for TEST_DATA_FILE.

@dsikka So these tests run when running the command python3 -m pytest tests, which is the standard testing pathway. Unless we want to move this file outside of the tests folder, this is likely the best way to skip the test

I actually think these tests being moved out would be better since generally speaking, the overall compute and memory required is significantly larger than any of our other tests and we never want users running it by default.
