All rights reserved.Public 2 Testing, J2EE and Java EE  Testing not addressed well by J2EE  Java EE helps enormously by providing a number of enabling features  Arquillian takes full advantage of these features  Not the only solution, but best-of-breed  Developer (unit and integration) testing focus for this talk – Arquillian can also help with performance, system, etc testing – Arquillian excels at integration/regression testing  I’ll primarily focus on JUnit, not TestNG – TestNG also supported by Arquillian

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 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

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  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
