A lot of time spent in Yelp tests is not the actual tests, but setting up the users/reviews/etc. to run the tests on. Currently Testify doesn't show timing information for @class_setup and @class_teardown methods, or include them in the "Total test time".
These tend to be the most expensive methods (otherwise we'd just use @setup or @teardown), so it's kind of a liability not to know just how expensive they are.
