如果您只想进行 _单元_测试，则无需启动任何服务器。如果您具有服务（业务层）或任何其他类似的
UriInfo东西，诸如此类的东西，则可以进行模拟。Mockito是一个非常流行的模拟框架。以下是一个完整的示例
import javax.inject.Inject;import javax.ws.rs.GET;import javax.ws.rs.Path;import javax.ws.rs.PathParam;import javax.ws.rs.core.Response;import org.junit.Before;import org.junit.Test;import org.mockito.Mockito;import static org.hamcrest.CoreMatchers.instanceOf;import static org.hamcrest.CoreMatchers.is;import static org.junit.Assert.assertThat;public class SomethingResourceUnitTest { public static interface SomeService { String getSomethingById(int id); } @Path("something") public static class SomethingResource { private final SomeService service; @Inject public SomethingResource(SomeService service) { this.service = service; } @GET @Path("{id}") public Response getSomethingById(@PathParam("id") int id) { String result = service.getSomethingById(id); return Response.ok(result).build(); } } private SomethingResource resource; private SomeService service; @Before public void setUp() { service = Mockito.mock(SomeService.class); resource = new SomethingResource(service); } @Test public void testGetSomethingById() { Mockito.when(service.getSomethingById(Mockito.anyInt())).thenReturn("Something"); Response response = resource.getSomethingById(1); assertThat(response.getStatus(), is(200)); assertThat(response.getEntity(), instanceOf(String.class)); assertThat((String)response.getEntity(), is("Something")); }}如果您要运行 _集成_测试，那么就个人而言，只要您没有在应用程序中使用特定于Tomcat的东西，我是否运行Grizzly容器与运行Tomcat容器都不会有太大区别。
使用Jersey测试框架是集成测试的不错选择，但它们没有Tomcat提供程序。只有Grizzly，In-
Memory和Jetty。如果您未使用任何Servlet
API，例如
HttpServletRequest或
ServletContext，等等，则内存中提供程序可能是可行的解决方案。这将为您提供更快的测试时间。
如果 必须
使用Tomcat，则可以运行自己的嵌入式Tomcat。我没有找到太多文档，但是DZone中有一个示例。我并没有真正使用嵌入式Tomcat，但是通过上一个链接中的示例，您可以看到类似以下的内容（已通过测试工作）
import java.io.File;import javax.inject.Inject;import javax.ws.rs.GET;import javax.ws.rs.Path;import javax.ws.rs.PathParam;import javax.ws.rs.client.ClientBuilder;import javax.ws.rs.core.Response;import org.apache.catalina.Context;import org.apache.catalina.startup.Tomcat;import org.glassfish.hk2.utilities.binding.AbstractBinder;import org.glassfish.jersey.server.ResourceConfig;import org.glassfish.jersey.servlet.ServletContainer;import org.junit.After;import org.junit.Before;import org.junit.Test;import static org.hamcrest.CoreMatchers.is;import static org.junit.Assert.assertThat;public class SomethingResourceTomcatIntegrationTest { public static interface SomeService { String getSomethingById(int id); } public static class SomeServiceImpl implements SomeService { @Override public String getSomethingById(int id) { return "Something"; } } @Path("something") public static class SomethingResource { private final SomeService service; @Inject public SomethingResource(SomeService service) { this.service = service; } @GET @Path("{id}") public Response getSomethingById(@PathParam("id") int id) { String result = service.getSomethingById(id); return Response.ok(result).build(); } } private Tomcat tomcat; @Before public void setUp() throws Exception { tomcat = new Tomcat(); tomcat.setPort(8080); final Context ctx = tomcat.addContext("/", new File(".").getAbsolutePath()); final ResourceConfig config = new ResourceConfig(SomethingResource.class) .register(new AbstractBinder() { @Override protected void configure() { bind(SomeServiceImpl.class).to(SomeService.class); } }); Tomcat.addServlet(ctx, "jersey-test", new ServletContainer(config)); ctx.addServletMapping("/*", "jersey-test"); tomcat.start(); } @After public void tearDown() throws Exception { tomcat.stop(); } @Test public void testGetSomethingById() { final String baseUri = "http://localhost:8080"; final Response response = ClientBuilder.newClient() .target(baseUri).path("something").path("1") .request().get(); assertThat(response.getStatus(), is(200)); assertThat(response.readEntity(String.class), is("Something")); }}
