Sample text

The biggest problem in this test class is the testCustomerAPI method. This test method is all over the place, asserting things about most of the API of the Customer bean. It starts off testing things about the customer but then moves to the invoices. Each test method should be focused on one aspect or intent of the API and should assert that one thing instead of several different, seemingly random parts of the API. Another thing to note is that a test class should focus on one subject class. Any tests that are written for the Invoice bean should be in a different test class altogether.

A. Often when applying this solution you will notice many pieces of the API that are not being tested. Add tests to cover the missing pieces while applying this solution. Example In this example, the CachedCustomerList JUnit test will be fixed so that it is no longer trapped in the pitfall. The first step in applying this solution is to find the simplest existing test method to start the cleanup on. Going back to the CachedCustomerListTest listing earlier, the simplest test method is testCustomerMap.

To test the title of the response it’s best to use the HttpUnit integration in Cactus. The HttpUnit framework provides many simple-touse APIs that make finding titles, buttons, and so on simpler. The endSimplePopulate method would change to look like this. getTitle()); } Checking the database is a bit more involved. The test needs to fetch some data from the database and assert that what is expected is what is there. To do that, a bit of JDBC code should be added to the test; specifically, there needs to be code to get a connection, execute a select statement, retrieve the results, and clean up.
