在使用SpringJUnit4ClassRunner的测试中加载Spring应用程序上下文失败

Question

    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration(locations={"/springMVC-config/mainController-servlet.xml"})
    public class DiagnosticsControllerTest {

    @Mock
    DiagnosticsService diagnosticsService;

    private DiagnosticsController diagnosticsController;

    private MockMvc mockMvc;

    @Before
    public void setUp() {
        MockitoAnnotations.initMocks(this);
        diagnosticsController = new DiagnosticsController();
        diagnosticsController.setService(diagnosticsService);
        this.mockMvc = MockMvcBuilders.standaloneSetup(diagnosticsController).build();
    }

    @Test
    public void shouldRun() {
        assertTrue(1 == 1);
    }
}

我得到的错误是：

我试图更改上下文配置的位置，如下所示：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("file:src/main/webapp/WEB-INF/springMVC-config/mainController-servlet.xml")
public class DiagnosticsControllerTest {
...
}

除了无法引用XML配置文件的正确路径之外,事实是：

在您提供的示例中，您甚至没有使用Spring TestContext框架。

相反，您只使用了Mockito和Spring MVC测试（即mockmvc)。
