Due to PATH ordering, shared directory/file names in a users codebase with the pythonFiles > unittestadapter directory will fail.

Error: ModuleNotFoundError: No module named 'utils.<name>; 'utils' is not a package

Problem:

• When running the test suite, we run discovery.py which adds unittestadapter to path at index 0.
• In some tests that import a file from utils, it will first search within the unittestadapter directory due to PATH ordering
• The discovery will now fail because it detects utils as a file and not a module since its reading the utils.py file from the unittestadapter directory.

Solution:

• Once starting to run discovery, add the projects root path to PATH at index 0 so that any further imports will use the projects root directory and not reference the incorrect directory.
• Since the test suite only allows the start_dir to be one directory deep, we can conclude that if the start_dir is not "." or contains a "/", that we need to add that start_dir's parent to PATH. Otherwise, we simply add the start_dir to PATH.
