"""
    The autotests.py runs the tests if any files change in the ./core/ folder.

    CODE COVERAGE ::
    Code coverage can be run by using `coverage run -m unittest discover`

    CODE COVERAGE REPORTS ::
    To create html coverage reports use `coverage html`, that creates a folder
    named /htmlcov/. Open /htmlcov/index.html using a browser to view the report

    note :: the reports must be created after running the coverage

    CODE COVERAGE INSTALL ::
    `pip install coverage`
