At Hint, we use Docker extensively. It is our development environment for all of our projects. On a recent greenfield project, we wanted to use Rails System Tests to validate the system from end to end.In order to comfortably use System Tests inside of Docker we had to ask ourselves a few questions:How do we use RSpec for System Tests?How do we run the tests in headless mode in a modern browser?Can we run the test in a non-headless browser for building and debugging efficiently?.
