Faster Rails tests

Feedback loop speed in one of the biggest contributing factors to overall development time. The faster you get results, the faster you can move on to other things. A fast enough test suite is therefore critical to teams' success, and is worth investing some time at the beginning to save in the long run.

Below is a list of techniques for speeding up a Rails test suite. It is not comprehensive, but should definitely provide some quick wins. This list of techniques assumes you're using minitest, but most everything should translate over to rspec by simply replacing test/test_helper.rb with spec/spec_helper.rb.

• Lead with data
• bcrypt
• bootsnap
• Cache Time::utc calls

Unless specified otherwise, all of the below tinting applies to both Lollipop and pre-Lollipop using AppCompat v21. To use the support version of these attributes, remove the android namespace.  For instance, "android:colorControlNormal" becomes "colorControlNormal".  These attributes will be propagated to their corresponding attributes within the android namespace for devices running Lollipop.  Any exceptions to this will be noted by including the "android:" prefix.

All Clickable Views:
-----------
* ripple effect (Lollipop only) -- "colorControlHighlight"

Status Bar:
------------
* background (Lollipop only) - "colorPrimaryDark"
