Major Description
The test class has an AfterMethod tearDown method, which drops a table and closes a session. But the session and the table don't get created until the test method of this class is run. Furthermore, this test depends on other test groups. So if any of the tests of those groups fail, the tests of this class won't be run. But the tearDown will still be run since setUp was run too.
Proposed fix is to drop the table and close the session in the test method itself.
