JerseyTest using GrizzlyWebTestContainerFactory in Jersey 2.13

Question

I am trying to get a JerseyTest running using a org.glassfish.jersey.test.grizzly.GrizzlyWebContainerFactory. I already searched the internet and tried several things for the better part of a day. It seems to be impossible and I would really appreciate any help on how to get this up and running.

I created a minimal example based on the code from the Jersey 2 documentation. The code looks like:

package test;

import static org.junit.Assert.assertEquals;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.core.Application;

import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.jersey.test.DeploymentContext;
import org.glassfish.jersey.test.JerseyTest;
import org.glassfish.jersey.test.ServletDeploymentContext;
import org.glassfish.jersey.test.grizzly.GrizzlyWebTestContainerFactory;
import org.glassfish.jersey.test.spi.TestContainerException;
import org.glassfish.jersey.test.spi.TestContainerFactory;
import org.junit.Test;

public class DistributedDeploymentTest extends JerseyTest {

@Path("hello")
public static class HelloResource {
    @GET
    public String getHello() {
        return "Hello World!";
    }
}

@Override
protected Application configure() {
    return new ResourceConfig(HelloResource.class);
}

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

@Override
protected DeploymentContext configureDeployment() {
    return ServletDeploymentContext.builder(configure()).build();
}

@Test
public void testSingleNode() throws Exception {
    final String hello = target("hello").request().get(String.class);
    assertEquals("Hello World!", hello);
}
}

It works perfectly fine without the GrizzlyWebTestContainerFactory. However upon running this example I always get:

I'm using the following Maven dependencies:

        <dependency>
            <groupId>org.glassfish.jersey.containers</groupId>
            <artifactId>jersey-container-servlet</artifactId>

        </dependency>

Solution

Not sure why it doesn't work with builder(configure()), but if we change it to

return ServletDeploymentContext.forPackages(
                                  getClass().getPackage().getName()).build();

(as seen here), it'll work (no need to override configure). You can see some more of the sample test configurations in jersey-test-framework-examples

EDIT

"But how do I add my custom subclass of ResourceConfig (not shown in the example above) in that case?"

return ServletDeploymentContext.forServlet(new ServletContainer(
                               new ResourceConfig(HelloResource.class))).build();

As seen here

Ok. Thanks. But how do I add my custom subclass of ResourceConfig (not shown in the example above) in that case?
