The Arquillian team is proud to announce the 1.0.0.Alpha2 release of the Arquillian Google Guice Extension component!

Some of the highlights in this release

Servlet integration

This release bring one new cool feature, integration with the Guice Servlet extension

The whole integration requires only two simple steps to make the test use the web configured Guice injector.

The first step is to replace the GuiceFilter with the ArquillianGuiceFilter:

<filter>
   <filter-name>guiceFilter</filter-name>
   <filter-class>org.jboss.arquillian.guice.api.servlet.ArquillianGuiceFilter</filter-class>
</filter>

<filter-mapping>
   <filter-name>guiceFilter</filter-name>
   <url-pattern>/*</url-pattern>
</filter-mapping> 

This can also be done at runtime; by doing a simple string replacement in the web descriptor when creating the deployment or by using ShrinkWrap Descriptors.

The second step is to annotate your test with @GuiceWebConfiguration. This will instruct the extension to retrieve the injector from the servlet context.

Example test:

@GuiceWebConfiguration
@RunWith(Arquillian.class)
public class WebInjectorTestCase {

   @Deployment
   public static Archive createTestArchive() {
       return ShrinkWrap.create(WebArchive.class, "guice-test.war")
               .addClasses(Employee.class,
                       EmployeeService.class, DefaultEmployeeService.class,
                       EmployeeRepository.class, DefaultEmployeeRepository.class,
                       EmployeeModule.class, EmployeeModuleContextListener.class)
               .addAsWebInfResource("WEB-INF/web.xml", "web.xml");
   }

   @Inject
   private EmployeeService employeeService;

   @Test
   public void testGetEmployees() {

       List<Employee> result = employeeService.getEmployees();

       assertNotNull("Method returned null list as result.", result);
       assertEquals("Two employees were expected.", 2, result.size());
   }
}

The test can go beyond a simple example like this and allow for injection of other resources like Guice configured servlets, filters and listeners.

We look forward to hearing your feedback about this release in the community forums!
