9. Copyright © 2012, Oracle and/or its affiliates. All rights reserved.Public 9 Testing CDI/EJB 3  CDI increases Java EE component model level testability by leaps and bounds  Embedded containers, generic dependency injection, @Alternative, portable extensions, XML deployment descriptors, interceptors enablers  Both mock object based unit testing as well as integration testing is possible  Likely best to stick with integration testing using close to the real runtime environment

10. Copyright © 2012, Oracle and/or its affiliates. All rights reserved.Public 10 Testing JPA  Embedded container, CDI and Arquillian integration works well for JPA  Consider using embedded databases like Java DB, Derby, HSQL  Defining data sources with the application - @DataSourceDefinition  You can use JPA 2.1 data loading, schema generation and DBUnit for better data consistency  Tests can use transactions  Take advantage of XML overrides
