>
> The current result handling in class QueryTest cannot consider return types
> of type java.lang.Object. Unique queries and queries using aggregates in the
> select expression (single exression, no group by) return objects rather than
> collections. The result handling must reflect this fact. As a consequence,
> the expected result in query test cases must be capable to consider a single
> object also.
> Currently, the expected result is declared as an object array in JDO2 query
> test classes. Method QueryTest.execute takes an object array as the expected
> result and an additional flag (unique) indicating if the query returns a
> single result. The unqiue parameter is calculated by methods in QueryTest
> executing query element holders. This is inadequate because the query element
> holder does not encapsulate the information of aggregates in single result
> expressions.
> We propose to adapt the signature and the implementation of method
> QueryTest.execute: The expected result should be of type java.lang.Object and
> the unique parameter should be removed. Thus, the unique information can be
> calculated inside the method.
> JDO2 query test classes in package query.api call method QueryTest.execute
> directly. These test cases must be adapted wrt the expected result: The
> expected result must be of the exact type which the query returns at runtime.
> Other test cases which do not call method QueryTest.execute directly may be
> adapted wrt the expected result as part of a separate issue.
