Querydsl release 0.4.4
Hi.
The newest release of Querydsl has now support for subqueries for JDOQL.
Is there some kind of conformance test suite to validate Querydsl as a
JDOQL implementation?
Release specific Querydsl documentation is found here :
http://source.mysema.com/display/querydsl/Documentation
Some query examples using JDOQL can be found on our SVN server :
https://source.mysema.com/svn/mysema/projects/querydsl/trunk/querydsl-jdoql/src/test/java/com/mysema/query/jdoql/
Br,
Timo Westkämper.

Yes, you are correct. Querydsl is just an API layer on top of JDO. What
I meant is that I could use the JDO2 TCK tests to make sure that all
queries can be constructed via Querydsl.
It would be at the same time a reference on how Querydsl queries are
serialized into single string JDOQL form.

But QueryDSL isn't a JDOQL implementation though is it ? You presumably take
your API input and convert it into a single-string form of JDOQL for use by
the actual JDOQL implementation (e.g DataNucleus). You don't execute the
query on the underlying datastore.
The JDO2 TCK test compliance with the JDO2 spec ... for the JDO
implementation. Specifically, those tests (in Apache JDO SVN) will use the
JDOQL API and single-string form, and test the results from those queries
(after execution on the datastore).
