How to unit test the Enhancer?
Hi,
I'd like to put together a couple of unit tests for the Enhancer mojo.
For this I had a look at openjpa-kernel module where the PCEnhancer is
located but could not find any tests.
How can I test if a persistence-enabled class has been enhanced as
expected from a unit test? Appreciate any pointers.
Cheers,
Rahul

Yep, totally agree there and I would love to 'scratch' this 'itch' as
well, but right now I am scratching many ;-). My intent was to see if
there was something I could readily use (like the resources pointed out
by yourself) or if it something was expected soon that would address
this (Patrick's other email covered that aspect).

I would like to get the testing set up at this stage when I don't have
too much code (openjpa maven plugin and an ORM generator module that I
want to use in Continuum) - so yes, I'd say this is important. Though I
am not sure how much time and effort I would be able to commit to it if
I picked it up.

Done, http://issues.apache.org/jira/browse/OPENJPA-105

OpenJPA is, like most Apache projects, a do-ocracy. If you have an
itch, you are encouraged to scratch it.
I'm just guessing here, but it's likely that a test suite that is
used for Kodo and not already contributed to OpenJPA has significant
resource constraints to make it suitable for OpenJPA.
If this is important for you, you will need to take the initiative to
propose a solution that you can implement.
The process for proposing a new feature would be to discuss it on
this alias (done) and then once there is concurrence that such a
feature would be useful (done), create a JIRA issue to track it. The
JIRA would then contain the further discussion on how to implement
the feature.

I hope to see more of the Kodo test suite make its way into OpenJPA over
time. It's not a concrete goal on our (BEA's) roadmap, though, so it
takes a back seat to things like getting releases out etc.

Hi Patrick,
Thanks for the pointer, I think something might be better than nothing -
I will use this approach to test the Enhancer!
When you say 'majority Kodo test suite has not yet made it into OpenJPA'
- do you mean that this is scheduled to happen sometime?
If not, are there plans to put together such tests into OpenJPA itself?
Thanks,
Rahul

You could also just test that the class implements
org.apache.openjpa.enhance.PersistenceCapable. Such a check assumes that
the OpenJPA enhancement is happening correctly under the covers, but
should be a good first approximation at least.
FTR, yes, there are tests for this stuff. Sadly, the majority of the
Kodo test suite has not yet made it into OpenJPA.

Hi Craig,
Thanks for that; that was closer to what I was I looking for in OpenJPA,
but I haven't found anything. Something I could use to verify in my own
unit test.
Any other pointers, anyone?
TIA,
Rahul

Hi Rahul,
You might look at the work-in-progress going on at Apache JDO http://
db.apache.org/jdo/ and http://wiki.apache.org/jdo/ProjectStructure.
The JDO 1.1 project includes an enhancer verification program that is
not yet updated for JDO 2.0, but it should give you some ideas on
what technology exists.
If you need more details after looking at the project, please feel
free to follow up on the jdo-dev alias.

Craig

Rahul-
If it worked, then the persistence tests should pass. E.g., the
following should work from the top-level of the project:
mvn clean test -Dtest=TestPersistence -Dopenjpa.loglevel=trace
