Question

我有一个RestController只有一个http GET方法，没有输入参数。它调用的服务方法需要一些参数。下面是控制器代码段。

@RequestMapping(value = "/leagueResults", method = RequestMethod.GET)
public List<LeagueTableEntry> getResults(){

    List<LeagueTableEntry> leagueTableEntryList = new ArrayList<>();

    List<Match> listOfMatches = getListOfMatches();

    leagueTableEntryList = leagueService.getResults(listOfMatches);

    return leagueTableEntryList;
}

以下是我的ControllerTest类代码段

@RunWith(SpringRunner.class)
@WebMvcTest(LeagueController.class)
@WebAppConfiguration
public class LeagueControllerTest {

@Autowired
private MockMvc mvc;

@MockBean
private LeagueService leagueService ;

private List<LeagueTableEntry> leagueEntryList;

private List<Match> matchList;

@Before
public void setUp() throws Exception 
{
    MockitoAnnotations.initMocks(this);
    createSampleInputData();//This method populates the instance variable matchList
    getLeagueEntryOutput();//This method populates the instance variable leagueEntryList 

}

@Test
public void checkNoOfRecordsReturned()throws Exception {
    try{
        Mockito.when(leagueService.getResults(matchList)).thenReturn(leagueEntryList);
         mvc.perform(get("/leagueResults").contentType(MediaType.APPLICATION_JSON))
                  .andExpect(status().isOk())
                  .andExpect(jsonPath("$", hasSize(4)));

    }
    catch(Exception e){
        throw new Exception();
    }
}

private void getLeagueEntryOutput(){
    leagueEntryList = new ArrayList<>();
    leagueEntryList.add(new LeagueTableEntry());
    leagueEntryList.add(new LeagueTableEntry());
    leagueEntryList.add(new LeagueTableEntry());
    leagueEntryList.add(new LeagueTableEntry());

}

所以，在这里，我希望返回列表中的对象数量为4，但它会变为0.因此，我的测试失败了。你能告诉我我错过了什么吗？

Answer 1

我认为你可以代替写作

Mockito.when(leagueService.getResults(matchList)).thenReturn(leagueEntryList);

写

Mockito.when(leagueService.getResults(Mockito.anyList())).thenReturn(leagueEntryList);

如果这不起作用，我需要得到

的实现

List<Match> listOfMatches = getListOfMatches();

Spring Boot Controller测试失败
