Spring Parameterized/Theories JUnit Tests

Question

I'm looking to combine the flexibility of Spring Profiles and Configurations with the parallel running of JUnit tests which utilize either the Parameterized or Theories annotation. Is there any way to incorporate all of these features to get my unit tests running?

The problem I keep running into is the parameters need access to an injected bean, which isn't possible since the function annotated with @Parameters or @DataPoints is supposed to be static. I'd really hate to have to wire that into each class or even a static function somewhere because I'd like to quickly be able to switch profiles without having to change Java code. Is this possible?

Answer 1

Found the ticket for this request. It seems the attached file has some issues though. Looks like it's been a feature request for quite some time now.

Answer 2

I've been looking for a solution of this problem too. And there is one ! But as it comes from somebody's blog, I can't take the credit for it however. :-)

Unfortunately I can't find the original blog any more...

@RunWith(Parameterized.class)
@ContextConfiguration("/beans.xml")
public class MyTest {

  private final File file;

  public MyTest(final File file) {
    this.file = file;
  }

  @Autowired
  private PlatformTransactionManager transactionManager;

  private TestContextManager testContextManager;

  @Parameterized.Parameters
  public static Collection<File[]> getFilesToTest() throws Exception {
    return getValidFiles();
  }

  @Before
  public void setUpSpringContext() throws Exception {
    testContextManager = new TestContextManager(getClass());
    testContextManager.prepareTestInstance(this); // does the autowiring !
  }

  @Test
  public void testInTransactionContext() throws Exception {
    new TransactionTemplate(transactionManager).execute(new TransactionCallback() {
      public Object doInTransaction(final TransactionStatus status) {
        status.setRollbackOnly();
        try {
          ... run the test ...
        } catch (Exception e) {
          throw new RuntimeException(e);
        }
        return null;
      }
    });
  }
}
