Just found the test for EJBQL fetch joins:  
DataContextEJBQLFetchJoinTest. It seems to be available on 3.1 and 3.0  
branches and it has a LEFT OUTER join test. Maybe you can look at it  
and see if the test is wrong.

The schema for the test DB is setup via static methods. See  
CayenneCase class (superclass of DB-aware unit tests) for details.

* To clean the DB, call CayenneCase.deleteTestData().

* There are various ways to create new data. We used Spring XML in  
3.0, in 3.1 we created a special helper subproject "cayenne-test- 
utilities". A release independent way would be to use SQLTemplate.
