[KRiedmiller]

From README:

To run the test locally, you must:

• install docker
• install act, easiest option is with github cli
  • install github cli (gh)
  • gh extension install https://github.com/nektos/gh-act
• run tests with gh extension exec act -j test --artifact-server-path ./artifacts
  • customize which python versions to test in tox.ini
  • html coverage report is exported into artifacts
