To start the service, I know one uses new MyService().run(args). How to stop it?

Thanks @LiorH for this great suggestion.

Here is a complete test class using the DropwizardServiceRule in dropwizard-0.6.2.

First create a service configuration for testing: testing-server.yml and place it in the test's class path (ex. src\test\resources). This way you can set different ports for the test service to use:

http:
  port: 7000
  adminPort: 7001

A simple test class that checks if there is a resource at the location "/request" looks like this:

class TheServiceTest {

    @ClassRule
    public static DropwizardServiceRule RULE = new DropwizardServiceRule(TheService.class,
            Resources.getResource("testing-server.yml").getPath());

    @Test
    public void
    dropwizard_gets_configured_correctly() throws Exception {
        Client client = new Client();

        ClientResponse response = client.resource(
                String.format("http://localhost:%d/request", RULE.getLocalPort()))
                        .get(ClientResponse.class);

        assertThat(response.getStatus(), is(200));
    }
}

I have also added the import in case you do not know what implementation to choose.

import com.google.common.io.Resources;
import com.sun.jersey.api.client.Client;
import com.sun.jersey.api.client.ClientResponse;
import com.yammer.dropwizard.testing.junit.DropwizardServiceRule;
import org.junit.ClassRule;
import org.junit.Test;
import org.junit.rules.TestRule;

import static org.hamcrest.core.Is.is;
import static org.junit.Assert.assertThat;

At the end of the tests, the server will shutdown gracefully, so you do not need to worry about it.
