单元测试 – 单元测试AngularJS服务

当使用$httpBackend来模拟AJAX post(whenPOST)时,你发布的对象是否决定响应？

这是我的服务和我的测试例如：

(function () {
    "use strict"

    var app = angular.module('cs');

    app.service('PlateCheckService',['$http',function ($http) {
        return {
            checkPlate: function (plateNumber) {
                return $http.post('PlateCheck/Index',{
                    plateNumber: plateNumber
                }).then(function (response) {
                    return {
                        message: response.data.VehicleAtl === null ? 'Clean' : 'Hot',alertClass: response.data.VehicleAtl === null ? 'alert-success' : 'alert-danger'
                    }
                });
            }
        }
    }]);

}());

    beforeEach(function () {
        module('cs');

        inject(function ($httpBackend,PlateCheckService) {
            httpBackend = $httpBackend;
            httpBackend.whenPOST('PlateCheck/Index',{ plateNumber: '123456' }).respond({
                response: {
                    message: 'Clean',alertClass: 'alert-success'
                }
            });
            httpBackend.whenPOST('PlateCheck/Index',{ plateNumber: '123456789' }).respond({
                response: {
                    message: 'Hot',alertClass: 'alert-danger'
                }
            });

            service = PlateCheckService;
        });
    });

    it('Should return a clean plate.',function () {
        var result;

        service.checkPlate('123456').then(function (response) {
            result = response;
        });

        httpBackend.flush();
        expect(result.message).toBe('Clean');
        expect(result.alertClass).toBe('alert-success');
    });
});

检测结果

Test 'Plate Check Service:Should return a clean plate.' failed
    Expected 'Hot' to be 'Clean'.
    Expected 'alert-danger' to be 'alert-success'.

看起来它没有考虑到我正在传递给服务器的服务器的plateNumber.

我本来会期待这个测试通过.

这有任何意义吗？
