Subject Re: Rollback transactions in unit testing
Date Mon, 29 Sep 2008 22:21:08 GMT

We are also using openejb for junit testing. In our tests we are using
UserTransaction to control the test data. Maybe  this approach might also
work for you. 
Below is the basic code, the startup and shutdown  of the container,  as
well as starting/stopping transaction could also be  moved to a base junit 
class. 
This works fine  with openejb 3.0, in 3.1-SNAPSHOT the UserTransaction can
be  retrieved with a jndi lookup (I think is java:openejb/UserTransaction)

public MyTest {

 static  MyService service;
 UserTransaction tx;

@BeforeClass
public static void  onBeforeClass() throws Exception{
   // start openejb embeded container  here
   InitialContext ctx  = new  IntialContext(props);
   // lookup service here
   service = (MyService)  ctx.lookup("java:openejb/MyServiceLocal");
 
}

@AfterClass
public static void  onAfterClass() throws Exception{
   // shutdown openejb
   OpenEJB.destroy();
}

@Before
public void onBefore() throws Exception{
  // start a UserTransaction for each  test method
  utx = new org.openejb.core.CoreUserTransaction()
  utx.begin();
}

@After
public void onAfter() throws Exception{
  utx.commit();  // you can do also a utx.rollback() here
}

//sample test  method
@Test
public void testServiceMethod() throws  Exception{
  service.doSomething();
}

}

Regards,
Andreas
