   • in the 'appsettings.json' file set 'SortEmployeeHierarchyOutput' to 'false'

4. For SORTED employee hierarchy output:

   • in the 'appsettings.json' file set 'SortEmployeeHierarchyOutput' to 'true'

How to Run Unit Tests

1. On the command line, navigate to the top level 'CodingChallenge_Python' directory

2. on the command line, type:

   • 'py -m unittest discover -s UnitTests -p '*UnitTests.py' -v'
