How to Test With Packs Rails

Packs is a tool that lets you move code between apps without changing the name specs. The test files are co-located next to the code they're testing, which can help speed up tests. There's still a lot of entangled code in Ruby and other programming languages such as C/C++ for example. But once you begin to disentangle things and start to manage that dependency graph, then less code will need to be loaded.
