Field Detail

testDb

protected transient boolean testDb

True if dealing with a test database. By convention make sure any test database has the word 'test' in its URL. When initializing the persistence technology in the derived class be sure to call setTestDb according to whether the URL contains 'test' in it. This is not used by the model exposer itself but can be used by other classes to know whether they are dealing with a test database or not. The PersistenceTestCase uses this valid to assert that it is only operating on test databases. Adding and removing objects from a live production system could have detrimental affects on the data store especially when the destroyTestObjects method removes all objects from the database!
