java – 如何单元测试Spring ResourceHandlerRegistry提供的静态

有关如何正确执行此操作的任何提示？以下是我的代码：

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(classes = {WebConfig.class})
public class HomeControllerTest {

private MockMvc mockMvc;

@Autowired
private WebApplicationContext webApplicationContext;

@Before
public void setUp() throws Exception {
    mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext)
                            .build();
}

@Test
public void testGetHomepage() throws Exception { //passing :)
    this.mockMvc.perform(get("/"))
            .andExpect(status().isOk())
            .andExpect(view().name("index"))
            .andExpect(forwardedUrl("/WEB-INF/pages/index.jsp"));
}

@Test
public void testGetResources() throws Exception {   // TEST FAILS :( with 404
    this.mockMvc.perform(get("resources/css/test.css"))
            .andDo(print())
            .andExpect(status().isOk())
            .andExpect(forwardedUrl("/resources/css/test.css"));
}

}

print()的输出：
