Summary: Making it simpler to setup tests w/ default config and objects. Less LoC in tests, lower setup cost when creating new test suites. Should I changelog? Issue fixed: #183 - [x] All tests pass. Demo project builds and runs. - [x] I added tests, an experiment, or detailed why my change isn't tested. Closes https://github.com/Instagram/IGListKit/pull/678 Differential Revision: D4921633 Pulled By: rnystrom fbshipit-source-id: fb4d08acb6ed0ba885cf56ce147f70b304301ff1
