Question

我正在使用Service测试我的httpBackend。在这种情况下，这是一个简单的get请求，我想测试（响应代码）。但我一直在收到错误：

TypeError: undefined is not a function (evaluating '$httpBackend.expectGET('/api/something').response({})') in test/spec/services/requests.js (line 22)
        test/spec/services/requests.js:22:51
        Error: Unsatisfied requests: GET /api/something in /bower_components/angular-mocks/angular-mocks.js (line 1812)
        verifyNoOutstandingExpectation@/bower_components/angular-mocks/angular-mocks.js:1812:74
        /test/spec/services/requests.js:28:48

这是服务：

angular.module('requestService', [])
  .factory('Request', ['$http', 'localConfig', 'Query', function($http, localConfig){
return {
      getRequest: function(fromDate, toDate) {
        return $http({
          url: '/api/something',
          method: "GET",
          params: {fromDate: fromDate,
                    toDate: toDate},
          headers: {
            'Content-Type': 'application/json; charset=utf-8'
          }
        })
      }
     }
  }]);

这就是我测试它的方式：

describe('Service: Request', function () {
  var reqService, $httpBackend;
  beforeEach(module('webapp'));
  beforeEach(module('requestService'));
  beforeEach(inject(function(Request, _$httpBackend_){
    reqService = Request;
    $httpBackend = _$httpBackend_;
  }));

  it('should test the response to be 200', function(){
    $httpBackend.expectGET('/api/something').response({});
    $httpBackend.flush();
  });

  afterEach(function(){
    $httpBackend.verifyNoOutstandingExpectation();
    $httpBackend.verifyNoOutstandingRequest();
  })
});

修改

我对我的测试进行了修改（如建议）：

it('should test the response to be 200', function(){
    console.log('service: ' + reqService);
    reqService.getRequest('2016-03-26', '2016-03-29');
    $httpBackend.expectGET('/api/something').respond({});
    $httpBackend.flush();
  });

现在我收到了这个错误：

 Error: Unexpected request: GET /api/something?fromDate=2016-03-26&toDate=2016-03-29
        Expected GET /api/something in /bower_components/angular-mocks/angular-mocks.js (line 1403)

Answer 1

您尚未调用getRequest服务功能，因此ajax调用永远不会被调用＆amp;这就是expectGET没有得到满足的原因。抛出Error: Unsatisfied requests:错误。同时修正response到respond

的拼写错误

it('should test the response to be 200', function(){
    //action
    reqService.getRequest();

    $httpBackend.expectGET('/api/something').respond({});
    $httpBackend.flush();
});

Answer 2

我认为您打算使用here，而不是response()：

$httpBackend.expectGET('/api/something').respond({});

TypeError：undefined不是函数
