这是我的服务:
var services = angular.module('amdotcom.services', ['ngResource']);
services.factory('homePageRes', ['$resource', '$window',
function ($resource, $window) {
var wdw = angular.element($window);
return $resource('home/index', {
height: wdw.height(),
width: wdw.width()
});
}]);
services.factory('homePageLoader', ['homePageRes', '$q',
function (homePageRes, $q) {
return function () {
var delay = $q.defer();
homePageRes.get(function (homePage) {
delay.resolve(homePage);
}, function () {
delay.reject('Unable to fetch home page');
});
return delay.promise;
};
}]);
以下是我在介绍$ window服务之前的测试。这些测试工作正常,但是一旦我介绍了$ window服务,我就无法嘲笑它。
describe('Services', function () {
beforeEach(function () {
module("amdotcom.services");
});
describe('homePageLoader', function () {
var mockBackend, loader;
beforeEach(inject(function ($httpBackend, homePageLoader) {
mockBackend = $httpBackend;
loader = homePageLoader;
}));
it('should return home page information', function () {
mockBackend.expectGET('home/index?height=400&width=500').respond({ "Albums": [{ "Id": 2, "Name": "best shots" }] });
var homePageData;
var promise = loader();
promise.then(function (homePg) {
homePageData = homePg;
});
expect(homePageData).toBeUndefined();
mockBackend.flush();
expect(homePageData.Albums[0].Id).toEqual(2);
expect(homePageData.Albums[0].Name).toEqual("best shots");
});
afterEach(function () {
mockBackend.verifyNoOutstandingExpectation();
mockBackend.verifyNoOutstandingRequest();
});
});
});
我收到的错误是:TypeError:' undefined'不是一个功能(评估' wdw.height()')
我尝试使用$ provider和spyOn方法,但都没有。请帮忙。

答案 0 :(得分:6)
显然,height()和width()函数不正确。我将它们更改为innerHeight和innerWidth属性。
services.factory('homePageRes', ['$resource', '$window',
function ($resource, $window) {
return $resource('home/index', {
height: $window.innerHeight,
width: $window.innerWidth
});
}]);
beforeEach(function () {
angular.mock.module("amdotcom.services", function ($provide) {
var myMock = {
innerHeight: 400,
innerWidth: 500
};
$provide.value('$window', myMock);
});
});
由于我上面的评论没有格式化且可读性较差,我已在此处再次添加。
