• Replaces barebones Travis CI configuration with Tox for more in-depth testing featureset and consistency across multiple dev environments
  Previously, you would manually install flake8 and use unittest manually to run tests. Tox builds entire virtualenvs with the required dependencies to run tests to mitigate the potential differences between developer environments.

• Switch out python unittest for pytest

• Add development requirements file

• Add code coverage with coverage.py through https://codecov.io/gh/mitre/caldera

• Add pre-commit configuration file that can be used by developers to catch potential errors before committed. It currently only runs flake8 and flake8-bugbear, but it will be incorporating the following pre-commit hooks in the future:

  - repo: https://github.com/pre-commit/pre-commit-hooks
    rev: v2.2.3
    hooks:
      - id: check-byte-order-marker
      - id: trailing-whitespace
        args: [--markdown-linebreak-ext=md]
      - id: end-of-file-fixer

The hooks do the following:

check-byte-order-marker

Forbid files which have a UTF-8 byte-order marker

trailing-whitespace

Trims trailing whitespace.

end-of-file-fixer

Makes sure files end in a newline and only a newline.
