我无法完成官方AngularJS教程的第二步。我正在尝试执行单元测试的说明。
我不相信我在源代码中更改了一个内容并按照教程进行了操作。可以找到教程中特定步骤的链接here。
这是我在控制台窗口中从Karma获得的错误：

这是我的controllers.js文件：
'use strict';
var phonecatApp = angular.module('phonecatApp', []);
phonecatApp.controller('PhoneListCtrl', function ($scope) {
$scope.phones = [
{'name': 'Nexus S',
'snippet': 'Fast just got faster with Nexus S.'},
{'name': 'Motorola XOOM™ with Wi-Fi',
'snippet': 'The Next, Next Generation tablet.'},
{'name': 'MOTOROLA XOOM™',
'snippet': 'The Next, Next Generation tablet.'}
],
$scope.name = "Anon";
});
//phonecatApp.controller('PhoneListCtrl', PhoneListCtrl);
/* Controllers */
var phonecatControllers = angular.module('phonecatControllers', []);
phonecatControllers.controller('PhoneListCtrl', ['$scope', 'Phone',
function($scope, Phone) {
$scope.phones = Phone.query();
$scope.orderProp = 'age';
}]);
phonecatControllers.controller('PhoneDetailCtrl', ['$scope', '$routeParams', 'Phone',
function($scope, $routeParams, Phone) {
$scope.phone = Phone.get({phoneId: $routeParams.phoneId}, function(phone) {
$scope.mainImageUrl = phone.images[0];
});
$scope.setImage = function(imageUrl) {
$scope.mainImageUrl = imageUrl;
}
}]);
这是controllersSpec.js文件，我甚至没有在教程第2步的说明中添加，因为它已经在Karma中为我产生了错误。
'use strict';
/* jasmine specs for controllers go here */
describe('PhoneCat controllers', function() {
beforeEach(function(){
this.addMatchers({
toEqualData: function(expected) {
return angular.equals(this.actual, expected);
}
});
});
beforeEach(module('phonecatApp'));
beforeEach(module('phonecatServices'));
describe('PhoneListCtrl', function(){
var scope, ctrl, $httpBackend;
beforeEach(inject(function(_$httpBackend_, $rootScope, $controller) {
$httpBackend = _$httpBackend_;
$httpBackend.expectGET('phones/phones.json').
respond([{name: 'Nexus S'}, {name: 'Motorola DROID'}]);
scope = $rootScope.$new();
ctrl = $controller('PhoneListCtrl', {$scope: scope});
}));
it('should create "phones" model with 2 phones fetched from xhr', function() {
expect(scope.phones).toEqualData([]);
$httpBackend.flush();
expect(scope.phones).toEqualData(
[{name: 'Nexus S'}, {name: 'Motorola DROID'}]);
});
it('should set the default value of orderProp model', function() {
expect(scope.orderProp).toBe('age');
});
});
describe('PhoneDetailCtrl', function(){
var scope, $httpBackend, ctrl,
xyzPhoneData = function() {
return {
name: 'phone xyz',
images: ['image/url1.png', 'image/url2.png']
}
};
beforeEach(inject(function(_$httpBackend_, $rootScope, $routeParams, $controller) {
$httpBackend = _$httpBackend_;
$httpBackend.expectGET('phones/xyz.json').respond(xyzPhoneData());
$routeParams.phoneId = 'xyz';
scope = $rootScope.$new();
ctrl = $controller('PhoneDetailCtrl', {$scope: scope});
}));
it('should fetch phone detail', function() {
expect(scope.phone).toEqualData({});
$httpBackend.flush();
expect(scope.phone).toEqualData(xyzPhoneData());
});
});
});
任何帮助都会非常感激 - 我尝试过很多不同的东西，但却无法让它发挥作用。 SO上的先前线程也没有帮助。
提前致谢＆amp;一切顺利！
答案 0 :(得分：1)
controller.js和controllersSpec.js的版本可能是step 4或更高版本。
以下代码在步骤4中添加。
$scope.orderProp = 'age';
https://docs.angularjs.org/tutorial/step_04
https://github.com/angular/angular-phonecat/compare/step-3...step-4
我想，你需要再次Workspace Reset Instructions。如下：
git checkout -f step-2
