I thought this evident but apparently not. You can download Drupal and run the tests provided. Just like that. If you download a few contribs and they have tests you still can run tests on any webserver, any environment what so ever to see whether they work together. It can be a small host or a cloud provider where all you have is the browser and no command line.
