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