Test Cleanup: Refactor tests to use helper (#1188)
Use `with_test_suite` helper to clean up existing test setup. This was more relevant when exploring #1156, but is still helpful for generators that are test suite agnostic. Also cleans up test setup by using a `file_fixture` that was missed in #1183
