Question

我正在尝试为控制器方法编写测试用例。但是我在org.mockito.exceptions.misusing.MissingMethodInvocationException中遇到错误，有人可以告诉我为什么我得到此异常的原因吗？在测试用例中我做错了什么？

帐户控制器取决于我正在使用Mockito的帐户服务。为了在帐户服务中实施populateGridView()，我使用了querydsl

AccountController

@GetMapping("/findAccountData")
    public ResponseEntity<List<Tuple>> populateGridViews(@RequestParam(value="sClientAcctId",required=false) String sClientAcctId,
                                                         @RequestParam(value="sAcctDesc",required=false) String sAcctDesc,
                                                         @RequestParam(value="sInvestigatorName",required=false)String sInvestigatorName,
                                                         @RequestParam(value="sClientDeptId",required=false) String sClientDeptId) throws Exception {
        return  ResponseEntity.ok(accService.populateGridViews(sClientAcctId, sAcctDesc,sInvestigatorName,sClientDeptId));
    }

AccountService

public List<Tuple> populateGridViews(String sClientAcctId, String sAcctDesc, String sInvestigatorName,
        String sClientDeptId)throws Exception{

    QAccount account = QAccount.account;
    QDepartment department = QDepartment.department;
    QAccountCPCMapping accountCPCMapping = QAccountCPCMapping.accountCPCMapping;
    QInvestigator investigator = QInvestigator.investigator;

    JPAQuery<Tuple> query = new JPAQuery<Tuple>(em);
    query.select(Projections.bean(Account.class, account.sClientAcctId, account.sAcctDesc, account.sLocation,
            Projections.bean(Department.class, department.sDeptName, department.sClientDeptId).as("department"),
            Projections.bean(Investigator.class, investigator.sInvestigatorName).as("investigator"),
            Projections.bean(AccountCPCMapping.class, accountCPCMapping.sCCPCode).as("accountCPC"))).from(account)
            .innerJoin(account.department, department).innerJoin(account.accountCPC, accountCPCMapping)
            .innerJoin(account.investigator, investigator);

    if (StringUtils.isNotEmpty(sClientAcctId)) {
        query.where(account.sClientAcctId.equalsIgnoreCase(sClientAcctId));
    }
  // code.......


    return query.fetch();       

}

AccountControllerTest

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class AccountControllerTest {

    @Autowired
    private MockMvc mockMvc;

    @Autowired
    private AccountService accountService;

       @Test
       @Transactional
        public void populateGridViewsTest() throws Exception {

            String sClientAcctId = "1122";
            String sAcctDesc = "SRI";
            String sInvestigatorName = "Ram";
            String sClientDeptId = "1200";      

            Tuple mockedTuple = Mockito.mock(Tuple.class);      

            List<Tuple> accountObj = new ArrayList<>();
            accountObj.add(mockedTuple);
            Mockito.when(accountService.populateGridViews(sClientAcctId, sAcctDesc, sInvestigatorName, sClientDeptId))
                    .thenReturn(accountObj);

            mockMvc.perform(
                    get("/spacestudy/$ InstituteIdentifier/admin/account/findAccountData")
                    .param("sClientAcctId", "1122")
                    .param("sAcctDesc", "SRI")
                    .param("sInvestigatorName", "Ram")
                    .param("sClientDeptId", "1200")
                    .accept(MediaType.APPLICATION_JSON))
                    .andExpect(status().isOk())
                    .andDo(print());        

            Mockito.verify(accountService).populateGridViews(sClientAcctId, sAcctDesc, sInvestigatorName, sClientDeptId);

        }
}

    Wanted but not invoked:

Actually, there were zero interactions with this mock.

您在此处使用“何时”方法。 when（）。thenReturn（）的语法为

when（mockedObject.methodName（parameter1，..，parameterN）.thenReturn（value）;

Mockito.when(accountService.populateGridViews(sClientAcctId, sAcctDesc, sInvestigatorName, sClientDeptId))
                .thenReturn(accountObj);

AccountService应该使用注释来模拟。它不应该自动接线。

@Mock
private AccountService accountService;

应该注意的另一件事是MockMvc对象不需要任何注释。

private MockMvc mockMvc;

创建一个MockMvc对象就足够了。希望对您有帮助...
