Testing SSL with Capybara and Selenium

I am using Capybara with Selenium as JS engine to write acceptance tests for a Ruby on Rails application. In some controllers I am forcing SSL with the “force_ssl” filter from Rails. By running the tests with Selenium this caused some problems. Selenium is launching Firefox and calls the URL Of course there is no SSL for localhost! This causes an error and the test fails.

I did some research for this. There are some tickets on GitHub and StackOverflow to this. but nothing what actually solves the core problem. For right now I just solved it, with running the filter only in production mode and not in test mode.

force_ssl if Rails.env.production?

Now Firefox is launching on
