1. Testing the Java EE
with Arquillian

4. Arquillian
Java EE testing is underestimated
Arquillian takes advantage of the most JEE features
Currently the best solution (but not the only)
Excels integration/regression testing
Can also help in performance, system etc. testing
Supports JUnit and TestNG

5. Testing Servlet
Traditional problems for bootstraping the container
– Arquillian coordinates the lifecycle
– Helps the isolation
HtmlUnit or HttpUnit comes very handy

6. Testing JSF2
Same concept as Servlet testing
JSF2 project stages useful for testing
– Development, production, system test, unit test
Drone/Selenium, Graphene for client side
Warp for complete JSF testing
– Both client and server side tests

7. Testing EJB3/CDI
EJB3 is unexpectedly testable
CDI increases Java EE component model level testability by leaps and bounds
Embedded containers, generic DI, @Alternative, XML Deployment, interceptors
Test enrichment via injection and scoping
Both Mock unit testing and integration testing possible
Close to real environment

8. Testing JPA
CDI/EJB3 and arquillian works great with JPA as well
– Still isolated JPA is possible
JPA 2.1 data loading and schema generation
@DataSourceDefinition within the application
XML overrides:
– persistence.xml
Embedded DB are recommended to be used
DBUnit coexist smoothly
Transactions can be used

9. Testing JAX-RS, WS
Same general concept
JAX-RS, WebSocket and JAX-WS client APIs can
be used arquillian
Can be automated with JMeter and SoapUI for
example

10. Summary
Robust and modern end-to-end solution for Java EE
EJB3, JPA2, CDI, JSF2, embedded containers, client APIs
key enablers
Rich set of features
Vibrant community
