Session in view with MockRoundtrip

[KR-11]

Hi,



In my ActionBeans I use lazy loading Hibernate entities that are accessed in
the JSP view.



Runtime this session in view pattern work excellent. But it does not work
during JUnit testing. The session is closed after calling execute on the
MockRoundtrip, making it impossible to check the results.



How can I make sure the session of the MockRoundtrip does not end after the
'execute' command?



Kind regards,

Karen

Hi Karen,

The solution I use is to "simulate" the OSIV filter in my TestCases. I
write a base test class that can open/close an hb session and tx, and
then use it in setUp/tearDown, or directly in test methods, like this
:

public void testMe() {
  Transaction tx = openSessionAndTransaction();
  try {
    // do some tests
   getSession().load(...);
   ...
  } finally {
    tx.commit();
  }
}

The base test class implements the methods for opening the session/tx,
binding it to the current thread, and closing it. Used in
setUp/tearDown, you don't even notice it's there, just like the
regular OSIV behavior...

Of course, depending on the type of OSIV you use, you'll have more or
less code to write to implement those methods in your base class. I'm
derivating from Spring's OSIV, and basically migrated the filter's
session/tx demarcation code into my base test class.

Cheers

Thanks Remi,

That's exactly what I want to do. Unfortunatly I failed to mention in my
opening post that I also use Stripersist (Stripesstuff) to manage
hibernate/JPA in my actionBeans. The Stripersist extension package does add
entity formaters, entity converters and a filter that starts and stops
transactions.

So when the MockRoundtrip is done executing the session is gone because the
Stripersist filter closed it.

Problem is, I just don't know of a way to manage the Stripersist transaction
manualy, without also disabeling the other extensions in the Stripersist
package (because my actionBeans also use entity formater and converter).

Hi again,

Well, I've never used JPA myself so I can't tell, but I guess you just
have to get hold of an EntityManager and do the open/close thing
inside a good old try/finally block...

Have a look at Stripersist's Interceptor, it just does this (plus some
classpath scanning and other things).
http://stripes-stuff.svn.sourceforge.net/viewvc/stripes-stuff/Stripersist/trunk/src/org/stripesstuff/stripersist/Stripersist.java?revision=123&view=markup

I think you just need to rewrite this class, probably as a "template"
that can be used in your tests.

Remi,

I'm fairly new to Java and Stripes, do you know if I can disable these
interceptors on the Stripersist class, so I can handle the JPA session my
selves?

For anybody interested we worked this out over IRC and there's a new MockStripersist class committed in SVN now. :-)
