jersey Bug connection: [1]: https://java.net/jira/browse/JERSEY-2412

The servlet request, response and context not injected

Answer 1

You need to configure the JerseyTest for a Servlet environment. In your JerseyTest, you should have something like

@Override
protected TestContainerFactory getTestContainerFactory() {
    return new GrizzlyWebTestContainerFactory();
}

@Override
protected DeploymentContext configureDeployment() {
    ResourceConfig config = new ResourceConfig(SessionResource.class);
    return ServletDeploymentContext.forServlet(
                             new ServletContainer(config)).build();
}

If you look at the ServletDeploymentContext.forServlet, it returns a ServletDeploymentContext.Builder. If you look at the Javadoc, you will see some familiar looking methods, like initParam(...,...), addListener, etc. This is just like building your web.xml programmatically. Just keep chaining methods, then build.

With the above configuration, you no longer need to override the configure method in the JerseyTest. Just add the ResourceConfig like seen above.
