Fabrial makes it easy to follow the "Arrange, Act, Assert" pattern in your tests. It makes it trivial to create your test data directly inline with your tests; removing the need for hard-to-maintain fixture files or blueprints.

Fabric is a small ruby app to perform tasks on servers via SSH. Built around net/ssh and taking heavy inspiration from Capistrano, it currently focuses on managing remote users and their keys on clusters of servers.

In the future, it will allow you to create policies for server management and perform sysadmin tasks via a system of recipes.
