Re: [jbosscache-dev] Testing JDBCCacheLoader - Embedding AS inside aUT?

I don't think the JBC testsuite is the place to test how the AS or Hibernate use it. Those tests belong in Hibernate or the AS. I do think the JBC testsuite should test the major known usage patterns that people like Hibernate use (e.g. simulate a read followed by a putForExternalRead) so any problems can be found quickly. But you shouldn't need the AS to do that. It would be great though if it were fairly easy to test a new version of JBC against the relevant releases of AS/Hibernate. E.g., perhaps a target in the AS/Hibernate testsuites that is able to execute the unit tests that involve JBC, along with some infrastructure to pull in the desired JBC release.

I'm not fundamentally disagreeing with what Manik said about integration tests though -- I don't like http session replication tests in the JBC testsuite, but that's different from tests of how JBC uses AS resources. A lot of JBC code assumes the presence of JEE resources; there should be tests of that code that are run in a real JEE environment. The JDBCCacheLoader case is one; another issue is the use of DummyTransactionManager in most unit tests in lieu of testing in the AS with a real transaction manager.
