This is where mocking frameworks comes in to play.

So we should some how mock the behavior of the dependencies.

We don’t want the unit test of the addCustomer() fail if there is a defect in save() method in the CustomerDao.We only want to test the logic inside the addCustomer() in isolation.We don’t want to call the real implementation of the CustomerDao save() method for a few reasons:

eg: we want to test the method addCustomer in CustomerService class, and within this addCustomer method, the save method of the CustomerDao class is invoked.

We want the unit tests to be independent of all other dependencies. When unit testing such methods, if we only used JUnit, our tests will also depend on those methods as well. and often times methods delegates some of the work to other methods in other classes, and we call these classes dependencies. Most of the classes we come across have dependencies.
