httpBackend.expectPUT 在 angularjs 工厂单元测试中不起作用

Question

以下是我尝试进行单元测试的示例服务：

    angular.module('sampleModule')
        .factory('sampleService', sampleService);

    sampleService.$inject = ['$http'];

    function sampleService($http) {
        var endpoint = "http://localhost:8088/api/customers/"
        return {
            getData: function(id){
                return $http({
                    method: 'GET',
                    url: endpoint + id
                });
            },
            updateData: function(id, requestBodyObject){
                return $http({
                    method: 'PUT',
                    url: endpoint + id,
                    data: requestBodyObject

                });
            }
        };
    }

以下是我必须测试上述服务的示例规范。但是它的抛出错误

    describe('Sample Service', function(){

        var service, httpBackend;

        beforeEach(function(){
            angular.mock.module('sampleModule');

            angular.mock.inject(function(_sampleService_, $httpBackend){
                service = _sampleService_;
                httpBackend = $httpBackend;
            });
        });


        it('updateAdvisorAttributesData should return response on valid acctNumber', function(){
            var response = {};
            var errResponse = {};
            var id = 1234;
            var requestBody = {
              '1': 'one'
            };
            var endpoint = "http://localhost:8088/api/customers/"

            httpBackend.expectPUT(endpoint + id, requestBody).respond(200, {'key': 'value'});

            service.updateData(id).then(function(result){
                response = result;
            },function(error){
                errResponse = error;
            });

            httpBackend.flush();
            expect(response.status).toBe(200);
            expect(response.data).toEqual({'key': 'value'});

        });
    });

执行规范时出错：

    Error: Expected PUT http://localhost:8088/biga/advisors/1234 with different data
    EXPECTED: {"1":"one"}
    GOT:      undefined

同样的方法适用于 httpBackend.expectGET()。然而，它的 PUT 失败了。为什么会失败？我该如何解决？

你在做测试时并没有通过身体。

变化：

service.updateData(id).then(function(result){

到：

service.updateData(id, requestBody).then(function(result){
