What it takes to add a new reactor:

• In pytest_twisted.py
  • Write an init_foo_reactor() function
  • Add 'foo': init_foo_reactor, to reactor_installers where the key will be the string to be passed such as --reactor=foo.
• In testing/test_basic.py
  • Add test_blockon_in_hook_with_foo() with skip_if_reactor_not('foo') as the first line
  • Add test_wrong_reactor_with_foo() with skip_if_reactor_not('foo') as the first line
• In tox.ini
  • Adjust envlist to include the fooreactor factor for the appropriate versions of Python
  • Add conditional deps for the new reactor such as foo: foobar to the appropriate test environments
  • Add fooreactor: pytest --reactor=foo to the commands list
• In .github/workflows/ci.yml
  • Consider any extra system packages which may be required
