Writing the CustomerIT and AddressIT Integration assessments How do we now attempt our constraints on our beans? We can’t quite write unit exams for @Email, because it is a constraints aggregation annotation, or for @ZipCode since it wishes injection to paintings (which is a box service). the best is to jot down an integration try out; that's, use the ValidatorFactory to get a Validator and validate our beans. directory 3-28 indicates the CustomerIT category that integration-tests the client bean. The init() strategy initializes the Validator (using the ValidatorFactory) and the close() technique releases the manufacturing unit.
