[jboss-user] [JBoss Seam] - Writing SeamTests with Seam 2.0.0. CR2 - What's Changed?

[bsmithjj]

Hello,

I used to be able to boot JBoss embedded from Seam tests in my app in the 1.2.1 and earlier days (was it only 6 months ago?).  Anyway, now when I run my tests, I am getting null-pointer exceptions from a class called SeamBaseTest.  For example:


  | public class PersistenceUnitConfigurationTest extends SeamTest {
  | 
  |     private Log log = LogFactory.getLog(PersistenceUnitConfigurationTest.class);
  | 
  |     @Test
  |      public void test_GetManagedPersistenceContext_from_Seam() throws Exception {
  | 
  |          new FacesRequest() {
  |              protected void invokeApplication() throws Exception {
  |                  EntityManager em = (EntityManager) getInstance("entityManager");
  |                  assert em != null;
  |              }
  |          }.run();
  | 
  |      }
  | }
  | 
 yields

  | -------------------------------------------------------------------------------
  | Test set: SampleEJB3Test
  | -------------------------------------------------------------------------------
  | Tests run: 1, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 0.198 sec <<< FAILURE!
  | test_GetManagedPersistenceContext_from_Seam  Time elapsed: 0.047 sec  <<< FAILURE!
  | java.lang.NullPointerException
  |         at org.jboss.seam.mock.BaseSeamTest$Request.run(BaseSeamTest.java:504)
  |         at com.javaplant.mapper.police.PersistenceUnitConfigurationTest.test_GetManagedPersistenceContext_from_Seam(PersistenceUnitConfigurationTest.java:22)
  | 

Ok - so it looks like there is now something called a ComponentTest, so I'll try that instead:


  | public class PersistenceUnitConfigurationTest extends SeamTest {
  | 
  |     private Log log = LogFactory.getLog(PersistenceUnitConfigurationTest.class);
  | 
  |     @Test
  |      public void test_GetManagedPersistenceContext_from_Seam() throws Exception {
  | 
  |          new ComponentTest() {
  | 
  |              protected void testComponents() throws Exception {
  |                  EntityManager em = (EntityManager) getInstance("entityManager");
  |                  assert em != null;
  |              }
  |          }.run();
  | 
  |      }
  | }
  | 
and this yields:


  | -------------------------------------------------------------------------------
  | Test set: SampleEJB3Test
  | -------------------------------------------------------------------------------
  | Tests run: 1, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 0.195 sec <<< FAILURE!
  | test_GetManagedPersistenceContext_from_Seam  Time elapsed: 0.07 sec  <<< FAILURE!

  |         at org.jboss.seam.mock.BaseSeamTest$ComponentTest.run(BaseSeamTest.java:164)
  |         at com.javaplant.mapper.police.PersistenceUnitConfigurationTest.test_GetManagedPersistenceContext_from_Seam(PersistenceUnitConfigurationTest.java:22)
  | 

So what's going on with SeamBaseTest?

Thanks,
