My application runs properly using Faye, Redis, Resque and other services, that I am starting every time with Foreman. Now I am writing acceptance tests with Capybara+RSpec, and I wonder how I could start Foreman (or even Faye alone) with Capybara in spec_helper to test live features.
One option is to not depend on these services in your tests. I know redis and resque have "mock" counterparts that behave like these services without actually needing to run them. Some services might not have a "mock" version (I can't find one for Faye), so you may just need to run them in the background.
