With Mockito you can not only mock methods to return something but also you can mock them to throw exceptions using Mockito.when. First of all, most of the time, assert operations are simple comparisons that get enabled in development and disabled in production. Remember, they're internal checks to make sure a developer's assumptions are correct. They should not change the behavior of the application.

In this case, the program will throw an exception if either of the two conditions following it evaluate to false.
