As everything in the world, applications became older. However, they can still be profitable and reliable. Such applications especially need testing, even if they are planned for refactoring. The stability and predictability of an application can be obtained only by writing tests for the most common execution methods. We will start with business expectations first, write characterization tests, and then proceed to refactoring. By completing this training, students will get the confidence to perform significant changes in the application.
