我正在测试一个springmvc控制器，它让一个Web服务客户端自动连接，并被嘲笑为vai-mockito。但这种嘲弄是行不通的。在测试中调用"verify（stuClient，times（1））.getAllStudents（sAndPCommand）；"返回
Wanted but not invoked:
stuClient.getAllStudents(
com.xyz.crudserviceclient.utilitybeans.SortablePagedCommand@3028e50e
);
-> at com.xyz.controllers.StudentControllerTest.testGetHomePage(StudentControllerTest.java:101)
Actually, there were zero interactions with this mock.
at com.xyz.controllers.StudentControllerTest.testGetHomePage(StudentControllerTest.java:101).....
以下是我在测试中的控制器方法：
@RequestMapping(value = "/getHomePage.do", method = RequestMethod.GET)
public ModelAndView getHomePage(@RequestParam(value = "first", required = false) Integer first,
@RequestParam(value = "max", required = false) Integer max, @RequestParam(value = "sortBy",
required = false) String sortBy,
@RequestParam(value = "sortDirection", required = false) String sortDir) {
ModelAndView mav = new ModelAndView("home");
SortablePagedCommand sortablePagedCommand = new SortablePagedCommand();
sortablePagedCommand.setFirst(first);
sortablePagedCommand.setMax(max);
sortablePagedCommand.setSort(sortBy);
sortablePagedCommand.setSortDir(sortDir);
PagedResult<StudentBean> students = studentServiceClient.getAllStudents(sortablePagedCommand);
List<StudentBean> studentList = students.getItems();
int noOfRecords = students.getUnfilteredItems();
int noOfPages = (int) Math.ceil(noOfRecords * 1.0 / max);
mav.addObject("sortByField", sortBy);
mav.addObject("sortDirField", sortDir);
mav.addObject("studentList", studentList);
mav.addObject("noOfPages", noOfPages);
mav.addObject("currentPage", first);
return mav;
}

你做错了——这显然是一个集成测试，为什么要涉及Mockito呢；此外，您正在将mock注入控制器字段，但您的测试并没有调用控制器字段——它们正在与Spring上下文中的控制器bean进行交互。
看看这个优秀的教程，尤其是单元测试部分。
总之，你的测试设置需要更改，你不需要任何注释，而且你必须为你的控制器使用独立的MockMvc设置：
public class StudentControllerTest {
private MockMvc mockMvc;
@InjectMocks
private StudentController controller;
@Mock
private StudentServiceClient stuClient;
@Before
public void setUp() {
MockitoAnnotations.initMocks(this);
mockMvc = MockMvcBuilders.standaloneSetup(controller).build();
Mockito.reset(stuClient);
}
