Test javax.ws.rs Rest WebService

I want to Test the following rest webservice API:

@Stateless
@Path("quotes")
public class QuoteService {

@Inject
QuotesLoaderBean quoteLoader;

@GET
@Path("getquote")
@Produces(MediaType.APPLICATION_JSON)
public String getQuote() {
    Gson gson = new GsonBuilder().create();
    return gson.toJson(quoteLoader.getQuote());
}

Therefore I wrote the following test method:

@Test
public void test() {
    Client client = ClientBuilder.newClient();
    client.property("MyProperty", "MyValue")
     .register(QuoteService.class);
    Response res = client.target("http://localhost:8080/example.rs.jax/rest/quotes/getquote").request().get();
    System.out.println(res);
}

The problem is, that this only works when the program is running. But I want to test the methods without starting the whole program. How can I achieve this?
