The progression of a J2EE application testing
What is happening ?
• Unit testing
• Functional testing
• Integration Testing
• Performance Testing

- Does these actions adapt Agile or extreme programming methodologies ?
- Still Integration testing is painful.
- Run time configuration
- Run time management
- Running the Tests
What is needed for the current ?

What is Arquillian ?
- is a container-oriented testing framework that enables
developers to create portable integration tests for enterprise
applications;
- is a JBoss Community project.
The Arquillian framework is broken up into three major sections:
 Test runners (JUnit or TestNG),
 Containers (Weld, OpenWebBeans, Tomcat, Glassfish, and so on),
 Test enrichers (integration of your test case into the container that
your code is running in).

- is a fluent API for creating archives such as JARs, WARs and EARs in Java;
- is also a JBoss Community project.

1. A remote container resides in a separate JVM from the test runner; Arquillian
binds to the container to deploy and un deploy the test archive and invokes
tests via a remote protocol(typically HTTP).
2. An embedded container resides in the same JVM as the test runner; lifecycle
managed by Arquillian; tests are executed via a local protocol for containers
without a web component (e.g., Embedded EJB) and via a remote protocol for
containers that have a web component (e.g., Embedded Java EE).
3. A managed container is the same as a remote container, but in addition, its
lifecycle (startup/
shutdown) is managed by Arquillian and is run as a separate process

What is happening ?
- The CDI Bean Manager is used to create a new bean instance.
- Arquillian injects the bean into the test class instance, before running any tests

Who care about run time ?
Here comes Arquillian.
Just add dependency in Maven,
Rest of the things actually taken care by the framework,
- starting the container run time
- packaging the stuffs
- deploying into the container
- un deploying the package
- Stopping the containers run time.

Test Enrichers:
@Resource: It defines references to any JNDI entry as per standard naming and
injection schemes.
@EJB: As long as you are including a deployed EJB in your archive, you can refer
to it as long as your target container includes EJB support. EJB JNDI entry
conventions remain intact. It is also worthwhile to note that Local and Remote
interfaces matter. When you deploy to a same JVM application server, or a
remote application server you must ensure that your injected test cases can see
the EJB reference appropriately.
@Inject: This is available as long as you have deployed a valid bean archive
(requires beans.xml in META-INF or WEB-INF).
And few more by extensions….

Pro’s and Con’s
-Con’s
- Maven hell
- one test class per @Deployment
- too much capabilities – bit large learning curve
-Pro’s
- Handy even for testers
- Portable
- flexible
- open source
