在AngularJS中模拟$ resource对象的构造函数

我正在使用AngularJS，我的测试在mocha + sinon + chai中

我要测试的代码如下所示：

addModal.result.then(function (clientFeature) {
                if (clientFeature) {
                    //create a new $resource ClientFeature object with result
                    var newClientFeature = new ClientFeature(clientFeature);
                    //push newly created clientfeature to list
                    $scope.clientFeatures.push(newClientFeature);

                    //make REST call to create new clientfeature
                    newClientFeature.$save({clientId: newClientFeature.client.id}, function (data, headers) {
                        console.log('created.');
                        console.log(data);
                    }, null);
                }
});

ClientFeature是$ resource对象：

“使用严格”；

angular.module('yrdyApp')
    .factory('ClientFeature', function ($resource, $location) {
        return $resource('https://' + $location.host() + ':port/clientfeatures/client/:clientId', {port: ':3333', clientId: '@clientId'}, {
            update: {method: 'PUT'}
        });
    });

我如何模拟这一行？

//create a new $resource ClientFeature object with result
var newClientFeature = new ClientFeature(clientFeature);

我现有的模拟：

        // set up mocks
    ClientFeatureMock = {
        query: sinon.spy(),
        update: sinon.stub()
    };

    // mock client feature object
    clientFeature = {
        client: {
            id: 100
        },
        $update: sinon.spy(),
        $save: sinon.spy()
    };

谢谢，肖恩

我不确定这是否是推荐的处理方式，但我决定不对服务进行存根/模拟。相反，我注入了实际的服务，并监视单个方法+设置httpBackend来拦截http请求。

// Initialize the controller and a mock scope
beforeEach(inject(function ($controller, $rootScope, _$timeout_, $q, $httpBackend, _ClientFeature_) {

    // inject actual service
    ClientFeature = _ClientFeature_;

    // set up httpBackend behavior
    httpBackend = $httpBackend;        
    httpBackend.whenGET(/https:\/\/.+\/clientfeatures\/client\/./).respond(200, []);

    // set up mocks
    ClientFeatureMock = {
        query: sinon.spy(ClientFeature, 'query')
    };

和一个示例测试：

it('should start by retrieving a list of clientfeatures for a client', function () {
    // flush/make the http call
    httpBackend.flush();
    ClientFeatureMock.query.should.be.called;
});
