Unit Testing Legacy Code in Java SE 8

Maintaining a codebase that is not tested or unclearly tangled and has no tests is one of the most difficult challenges developers face in their careers. This course Unit Testing Legacy Code Java will teach you how to test a legacy Java application. It is a small, but real, Java application that provides services to an emergency room. As you work on the application, it will be tested incrementally. You will first learn about the different types of tests that you can use to build a safety net around your application. You will then learn crucial dependency-breaking methods that allow you to create seams in order to provide test duplicates without affecting the code. You will also learn how to handle difficult to understand code. You will be able to effectively manage untested systems that you have been assigned.
