How to test Java EE applications
• No direct support (i.e. testing features) within the platform
• Although, Java EE provides other features that enable testing
– Arquillian is an integration testing platform that takes advantage of these features
• Other solutions available, but Arquillian is considerably the best

• What we’re doing with it
– Using Adapters internally
– Contributing to project – REST
• Adapters available now

Testing Servlets
• How to bootstrap containers from tests
– Arquillian does this by coordinating lifecycle
– Production-like environment
– Isolated tests
• JAX-RS Client API helps a lot, being the caller
– Other alternatives are HtmlUnit, HttpUnit, Arquillian Warp extension
– Java SE 9 considering a better native HTTP client API

Testing JAX-RS, WebSockets, JAX-WS
• Same concept as Servlets testing
• You can use the client APIs, of these specifications, with Arquillian
• For more complex tests consider tools like soapUI for REST/SOAP
– JUnit integration possible
@brunoborges

Testing JSF
• JSF 2 stages invaluable for debugging and testing
– You want production-like testing
• Arquillian Warp extension is complete for JSF testing
– Client and Server-side testing
• Navigate to a JSF page, then check state on Server-side
• Drone/Selenium, Graphene often sufficient
– Client-side only

Testing EJB 3 and CDI
• EJB 3 much more testable as they are simple POJOs now
• Testing enabled either by
– Embedded containers
– Generic POJO dependency injection
– @Alternative
– XML deployment descriptors
– Interceptors
• Arquillian test enrichment through injection/scoping
• Both mock object testing and integration testing are possible
@brunoborges

12. Copyright © 2016, Oracle and/or its affiliates. All rights reserved. |
Testing JPA
• CDI, EJB 3 and Arquillian works towards JPA testing
– Isolated JPA testing possible, but unecessary
• JPA 2.1 data loading, schema generation
• Define data sources within the application, not in the container
• persistence.xml and orm.xml overrides
• Use embedded databases like Java DB, Derby, HSQL
• Tests can have transactions in Arquillian
