This tutorial depends on Part I: Creating new DAOs and Objects in AppFuse.

About this Tutorial

In the context of AppFuse, this is called a Manager class. It's main responsibility is converting backend data (POJOs) into front-end data (Struts ActionForms). The main reason I even use Managers, rather than just calling the DAOs directly is testability. It's nice to be able to populate a Form manually (in the test) and call the DAO to persist it, and verify the database gets the proper results. The Business Delegate pattern from Sun says that these objects are useful for de-coupling your presentation layer from your database layer (i.e. for Swing apps). Managers should also be where you put any business logic for your application.

I will tell you how I do stuff in the Real World in text like this.

Let's get started by creating a new ManagerTest and Manager in AppFuse's architecture.

Create a new ManagerTest to run JUnit tests on the Manager [#1]

This may seem redundant (why all the tests!), but these tests are GREAT to have 6 months down the road.

This class should extend BaseManagerTestCase, which already exists in the service package. The parent class (BaseManagerTestCase) serves the same functionality as the BaseDaoTestCase - to load a properties file that has the same name as your *Test.class, as well as to initialize Spring's ApplicationContext.

I usually copy (open → save as) an existing test (i.e. UserManagerTest.java) and find/replace [Uu]ser with [Pp]erson, or whatever the name of my object is.

The code below is what we need for a basic JUnit test of our Managers. It created and destroys our PersonManager. The
