In the following example, assume MyClass has a constructor that takes a std:: Because some classes may have references to other classes, testing a class can frequently spill over into testing another class. It is not as easy to create unit tests when a major function of the method is to interact with something external to the application.

Have you ever wrote JUnit tests extending a class that does some before and after work, so you didn’t have to repeat that code in various test classes? Well, I will not say that you have been doing it wrong, but, sure enough, you could do it better. How? Using JUnit Rules!

Functional tests may be user facing, in which case they are written by developers together with users (or maybe with the right tools and right users even by the users themselves), for users, from the user's perspective.
