单元测试 – 单元测试AngularJS服务

我试图找出如何测试我的AngularJS服务,它依赖于$http.

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'
                    }
                });
            }
        }
    }]);

}());

    var httpBACkend,service;

    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？
