Question

我有以下控制器样式，用于向DataTable显示结果。

settings.gradle

和我的DataTablesParamUtility

@RequestMapping(value = "/list", method = RequestMethod.GET)
    @ResponseBody
    public DataTableObject<PatientBO> list(HttpServletRequest request,
            Locale locale) {
        final DataTableRequestParam param = DataTablesParamUtility
                .getParam(request);
        Map<Integer, String> tableColumn = new HashMap<Integer, String>();
        if (tableColumn.isEmpty()) {
            DataTableUtil.createMap(tableColumn, param.columnProperties);
        }
        return adminPatientManagementService.getList(tableColumn, param,
                locale);
    }

现在我在尝试对我的控制器运行单元测试时遇到问题。这就是我到目前为止所拥有的

public class DataTablesParamUtility {

    public static DataTableRequestParam getParam(HttpServletRequest request)
    {
        if(request.getParameter("sEcho")!=null && request.getParameter("sEcho")!= "")
        {
            DataTableRequestParam param = new DataTableRequestParam();
            param.sEcho = request.getParameter("sEcho");
            param.sSearchKeyword = request.getParameter("sSearch");
            param.bRegexKeyword = Boolean.parseBoolean(request.getParameter("bRegex"));
            param.iDisplayStart = Integer.parseInt( request.getParameter("iDisplayStart") );
            param.iDisplayLength = Integer.parseInt( request.getParameter("iDisplayLength") );
            param.iColumns = Integer.parseInt( request.getParameter("iColumns") );
            param.sSearch = new String[param.iColumns];
            param.bSearchable = new boolean[param.iColumns];
            param.bSortable = new boolean[param.iColumns];
            param.bRegex = new boolean[param.iColumns];
            for(int i=0; i<param.iColumns; i++){
                param.sSearch[i] = request.getParameter("sSearch_"+i);
                param.bSearchable[i] = Boolean.parseBoolean(request.getParameter("bSearchable_"+i));
                param.bSortable[i] = Boolean.parseBoolean(request.getParameter("bSortable_"+i));
                param.bRegex[i] = Boolean.parseBoolean(request.getParameter("bRegex_"+i));
            }

            param.iSortingCols = Integer.parseInt( request.getParameter("iSortingCols") );
            param.sSortDir = new String[param.iSortingCols];
            param.iSortCol = new int[param.iSortingCols];
            for(int i=0; i<param.iSortingCols; i++){
                param.sSortDir[i] = request.getParameter("sSortDir_"+i);
                param.iSortCol[i] = Integer.parseInt(request.getParameter("iSortCol_"+i));
            }
            param.searchableColumns = request.getParameter("searchableColumns");
            param.columnProperties = request.getParameter("columnProperties");
            param.filterBy = request.getParameter("filterBy");
            param.customSearch  = request.getParameter("customSearch");
            param.startRange  = request.getParameter("startRange");
            param.endRange  = request.getParameter("endRange");
            return param;
        }else
            return null;
    }
}

测试失败，因为@Test public void testGetPatientList() throws Exception { PatientBO p1 = new PatientBO(); p1.setId(1); p1.setFirstName("Daenerys Targaryen"); PatientBO p2 = new PatientBO(); p2.setId(2); p2.setFirstName("John Snow"); List<PatientBO> patientList = Arrays.asList(p1,p2); DataTableObject<PatientBO> dto = new DataTableObject<PatientBO>(); dto.setAaData(patientList); when(patientManagementService.getList(null, null,null)).thenReturn(dto); mockMvc.perform(get("/staff/patient/list")) .andExpect(status().isOk()) .andExpect(content().contentType(MediaType.APPLICATION_JSON_VALUE)) .andExpect(jsonPath("$", hasSize(2))) .andExpect(jsonPath("$[0].id", is(1))) .andExpect(jsonPath("$[0].firstName", is("Daenerys Targaryen"))) .andExpect(jsonPath("$[1].id", is(2))) .andExpect(jsonPath("$[1].firstName", is("John Snow"))); verify(patientManagementService, times(1)).getList(null, null,null); verifyNoMoreInteractions(patientManagementService); }变量为null。我的问题是

我的控制器设计单元是否可测试？
我的单元测试应如何编写？

如果使用spring SpringBootTest，可以像下面一样测试端点：

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT,
                classes = MyApplication.class)
public class DataTableObjectTest {
    @Autowired
    private TestRestTemplate restTemplate;

    @Test
    public void testDataList() {

        DataTableObject<PatientBO> dto
            = (DataTableObject<PatientBO>) restTemplate.exchange("/list",
                                                                  HttpMethod.GET,
                                                                  request,
                                                                  DataTableObject.class);

        // perform the asserts of dto
    }
}

注意：MyApplication类是您的spring boot入门类。
