There are a few methods for running tests locally.

#### `tox`
`tox` takes care of managing Python virtualenvs and installing dependencies in order to run tests. You can also run tests in parallel. For example, you can run unit tests for Python 3.8, Python 3.9, Python 3.10, and `flake8` checks in parallel with `tox -p`. Also, you can run unit tests for specific python versions with `tox -e py38`. The configuration of these tests are located in `tox.ini`.
