Better Jasmine Tests With this

On the Refinery29 Mobile Web Team, codenamed "Bicycle", all of our unit tests are written using Jasmine, an awesome BDD library written by Pivotal Labs. We recently switched how we set up data for tests from declaring and assigning to closures, to assigning properties to each test case's this object, and we've seen some awesome benefits from doing such.

Up until recently, a typical unit test for us looked something like this:

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.
