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.
