Summary: Transaction tests wrong status
Initial Comment:
Some of the more recent JBoss tests are based around
ensuring the status returned for committed/rolledback
transaction is correct. For example:
TransactionManager.begin()
Transaction tx = TransactionManager.getTransaction();
TransactionManager.commit();
If ( tx.getStatus() !=
Status.STATUS_NO_TRANSACTION ) {
fail;
}
Else
{
pass;
}
Unfortunately the JTA spec. mixes some wrong concepts
and is poorly defined here (yet again). The test above
may be valid if performed on the TransactionManager
instance and not the transaction *if and only if* there
are no heuristic outcomes (in which case the transaction
won't be disassociated from the invoking thread and so
getStatus will be performed on the underlying
transaction object.)
If the test is performed on the actual transaction object
(as it currently is) then not only won't it work if
heuristics are present, but it's also implementation
dependant as to whether the transaction object has to
return STATUS_NO_TRANSACTION on successful
commit - it could return STATUS_COMMITTED (or even
STATUS_ROLLEDBACK if it rolled back).
On the assumption that the tests are just supposed to
make sure that transactions ended the way the test
requested *and* thread disassociation occurred, it
would make more sense to move the test to be on the
TransactionManager rather than the Transaction.
Ignoring heuristics (for which you'd want the test to fail
anyway), this is the best way to guarantee that the
test will work regardless of the underlying
implementation.
Mark.
