14.5. Summary

In this chapter, we started with an exploration of testing enterprise applications and the challenges that have traditionally faced developers. We also looked at the different types of testing performed by developers, quality engineers, and customers; and we refined our focus to look specifically at developer tests for EJB and JPA applications.

In the section on unit testing, we looked at how to test entity classes and then pulled back to look at how to test session beans in combination with entities in a unit test environment. We introduced the concept of mock objects and explored how to test code that depends on the entity manager without actually using a real entity manager.
