Question

我正在编写一些代码来使用Mockito和Junit测试Web服务，因此我在hasSize（2）中遇到了问题，我注入了控制器并调用了findAll wich方法，该方法返回Employe的列表，但是出错坚持，在调试模式下它告诉我集合为空，但是不是。错误是：

java.lang.AssertionError：JSON路径“ $”预期值：大小<2>，但：集合大小为<0>

这是课程：

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest
public class GestionPointage3ApplicationTests {

        private MockMvc mockMvc;
        @InjectMocks
        private EmployeController employeeController ; 
        @Mock
        private EmployeService employeeService;
        @Mock
        private ModelMapper modelMapper;
        @Before
        public void setUp() throws Exception{
            MockitoAnnotations.initMocks(this);
            mockMvc=MockMvcBuilders.standaloneSetup(employeeController).build();
        }

        @Test
        public void testgetAllEmployeeWithModelMapper() throws Exception{
            Employe emp1 = new Employe("Hamza", "Khadhri", "hamza1007", "123");
            Employe emp2 = new Employe("Oussema", "smi", "oussama", "1234");
            List<Employe> Employees= Arrays.asList(emp1, emp2);

            EmployeDTO dto1 = new EmployeDTO("Hamza", "Khadhri", "hamza1007", "123");
            EmployeDTO dto2 = new EmployeDTO("Oussema", "smi", "oussama", "1234");
            //when(modelMapper.map(emp1,EmployeDTO.class)).thenReturn(dto1);
           // when(modelMapper.map(emp2,EmployeDTO.class)).thenReturn(dto2);
            when(employeeService.findAll()).thenReturn(Employees);


            mockMvc.perform(get("/employe/dto"))
                .andExpect(status().isOk())
                .andExpect(MockMvcResultMatchers.content().contentType(MediaType.APPLICATION_JSON_UTF8_VALUE))
                .andExpect(jsonPath("$", hasSize(2)))
                .andExpect(jsonPath("$[0].nom", is("Hamza")))
                .andExpect(jsonPath("$[0].prenom", is("Khadhri")))
                .andExpect(jsonPath("$[0].login", is("hamza1007")))
                .andExpect(jsonPath("$[0].mp", is("123")))
                .andExpect(jsonPath("$[1].nom", is("Oussema")))
                .andExpect(jsonPath("$[1].prenom", is("smi")))
                .andExpect(jsonPath("$[1].login", is("oussama")))
                .andExpect(jsonPath("$[1].mp", is("1234")));

            verify(employeeService,times(1)).findAll();
            verifyNoMoreInteractions(employeeService);

        }

    }

这是控制器：

@CrossOrigin(origins = "*", allowedHeaders = "*")
@RestController
@RequestMapping("/employe")
public class EmployeController {

    @Autowired
    private EmployeService employeService;

    @Autowired
    private ModelMapper modelMapper;

    @GetMapping("/dto")
    public List<Employe> findAll() throws Exception{
    return employeService.findAllEmployeActive(); 
    }   
}

方法签名：

public List<Employe>findAll() throws Exception;     
public List<Employe>findAllEmployeActive() throws Exception;

Answer 1

您正在嘲笑EmployeeService并告诉被模仿的实例在调用Employee方法时返回findAll()列表（包含两个项目）：

when(employeeService.findAll()).thenReturn(Employees)

但是在EmployeeController中，您实际上是在EmployeeService上调用另一种方法：

return employeService.findAllEmployeActive()

因此，您应该像这样更新嘲笑的期望：

when(employeeService.findAllEmployeActive()).thenReturn(Employees)

期望集合大小为2，但集合大小为0？
