Creating tests for an EJB session facade

You can use the EJB session facade test pattern to verify the implementation of the session facade design pattern. The session facade test pattern generates tests for the session facade and for the methods in a subsystem (usually an entity bean) that are called by the session facade.

To create a test for testing the implementation of the session facade design pattern of the EJB under test:
  1. Click File > New > Other > Component Test > EJB > EJB Component Test and click Next.

    This starts the Create Test for EJB wizard.

  2. On the first wizard page, take one of the following actions:
    • Select the test project that will contain the test and click Next.
    • Click New to start the process of creating a new test project.

    At this point, a static analysis is performed on the EJBs associated with the test project. These files were selected during the creation of the test project and serve to define the scope of the test. (To update the list of files in the project, modify the Test Scope properties for the test project.)

    When the analysis is complete, you will see a list of components in a table format and sorted according to the computed metrics. You can use the guidance that these metrics provide to decide which EJB components are most important for you to test. Components with highlighted values or high numerical values are considered high-priority test candidates. For testing a session facade, it is especially useful to test components with a high Fan Out value.

  3. On the "Select the components" under test page, select the components you want to include in the test and click Next.
  4. On the "Select a test pattern" page, select EJB session facade testing and click Next.
  5. On the "Select the EJB interfaces" page, select the interfaces (local or remote) you want to use to perform the test.
    Note: You cannot test an EJB through its local interface and through its remote interface within the same component test or test suite. You must create one component test to test through the local interface and a second component test to test through the remote interface. You can store the two component tests in the same test project.
  6. On the "Select the methods under test" page, select the create method that creates the EJB session facade under test. Then, select the individual methods to be tested and click Next.
  7. On the "Select the methods behind the facade" page, select the methods to be tested from the subsystem (usually an entity bean) behind the session facade.
    1. Click on a particular method to display which EJB it belongs to. If the method you have selected belongs to the Local or Remote interface of the EJB, you can also choose the method to create the EJB instance on which this method will be applied.
    2. When you have selected the methods to be tested, click Finish.
    The end result is a test behavior script and a test suite with one test case for the session facade under test and another test case to test the methods behind the facade (the subsystem). The test behavior script contains code for testing the session facade under test as well as the methods behind the facade.

After you create the test, be sure to populate the test data table with test data. To display a test data table, take one of the following actions:
