-Just like application code, a test starts slowly. At the mountain's peak, the test is in its simplest form.

 As the testing suite grows in maturity and scope, teams should naturally create more efficient frameworks for running tests, managing notifications, analyzing results, and reporting. In this way, testing can start very simply, usually around the most critical or high-risk functionalities of the application, then evolve and improve organically along with the application.
