Previously, information about each test-suite was repeated in 3 separate places: - as a label and as implicit knowledge in the test-suite itself, - as a comment in Main.hs, and - as a configuration in SpecHelper.hs. With this change, there will be a single source of truth in the test suite itself. This will allow a single test-suite to easily test multiple different configurations.
