Time-saving Rails Commands - RailsCasts
Now that we don’t have to start up our Rails application every time we run one of these commands the output appears much sooner. Zeus works by preloading Rails in the different environments, development and test, and if we had Cucumber set up in this app it would work for that as well. This means that we can run commands against these preloaded environments. Zeus is also smart about reloading any changes. If we make a change to a model, for example, then this will be picked up automatically and we won’t have to reload Zeus. Let’s compare the time taken to run a command with and without Zeus. We’ll try running the database migrations.
