* Coverage
* We shoot for 100% in SimpleCov (So all the Ruby is tested)
* Some consider this too high or too burdensome -- I don't
* If it's 100%, you instantly know if you have any untested code
* If it's, say, 94%, and you add 100 lines, six of those can be untested -- hope they're perfect!
* In other words, at less than 100% coverage, you don't know if your new feature is fully covered or not
* Occasionally you have to ignore some code -- e.g. something that only runs in production
* Flaky tests are bad
* They eat up a lot of development time (esp. as build times increase)
