Description

jersey-test starts jetty which answers requests in a separated thread. since ds test-control just handles the thread of the test itself, it's needed to integrate jetty and jersey with the cdi-container. usually that's done via a ServletRequestListener - the following part describes an alternative approach for jersey-test:

//use: -Djersey.config.test.container.factory=custom.CdiAwareJettyTestContainerFactory

@RunWith(CdiTestRunner.class)
public class SimpleCdiAndJaxRsTest extends JerseyTest
{
  //...
}

or

public class CdiAwareJerseyTest extends JerseyTest
{
    static
    {
        System.setProperty("jersey.config.test.container.factory", CdiAwareJettyTestContainerFactory.class.getName());
    }
}

@RunWith(CdiTestRunner.class)
public class SimpleCdiAndJaxRsTest extends CdiAwareJerseyTest
{
    //...
}

public class CdiAwareJettyTestContainerFactory implements TestContainerFactory
{
    @Override
    public TestContainer create(final URI baseUri, final DeploymentContext context) throws IllegalArgumentException
    {
        return new CdiAwareJettyTestContainer(baseUri, context);
    }
}

CdiAwareJettyTestContainer is a copy of JettyTestContainerFactory.JettyTestContainer but with

HandlerWrapper cdiHandlerWrapper = new CdiAwareHandlerWrapper();
cdiHandlerWrapper.setHandler(this.server.getHandler());
this.server.setHandler(cdiHandlerWrapper);

after the line with JettyHttpContainerFactory#createServer

//activate the request-context e.g. via:
public class CdiAwareHandlerWrapper extends HandlerWrapper
{
    @Override
    public void handle(String target, Request baseRequest, HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException
    {
        CdiContainer cdiContainer = CdiContainerLoader.getCdiContainer();

        try
        {
            cdiContainer.getContextControl().startContext(RequestScoped.class);
            super.handle(target, baseRequest, request, response);
        }
        finally
        {
            cdiContainer.getContextControl().stopContext(RequestScoped.class);
        }
    }
}
