Question

我其实不喜欢那个人，但我一直坐着这个现在有些问题。我有这三个文件作为一部分更大的angularjs应用。我甚至无法得到这个基本的测试通过（甚至工作）。我一直在比较项目中的文件，我已经在网上阅读了（尝试了人们建议的所有方式）。我有甚至从头开始写几次文件。我可能不会再看看我的错误了。我想这更容易发现（马上）对于后座车手。

我非常感谢任何帮助。

模块声明

(function(){
'use strict';

angular.module('application.service', []);

})();

服务本身

(function () {
  angular.module('application.service')
    .service('SiteDescriptorService',
         ['$http', '$q', function ($http, $q) {
         var lastRequestFailed = true,
             promise,
             items = [];

         return {
             name: 'SiteDescriptorService',

             getItems: function () {
             if (!promise || lastRequestFailed) {
                 promise = $http.get('site.json').then(
                 function (response) {
                     lastRequestFailed = false;
                     items = response.data;
                     return items;
                 }, function (response) {  // error
                     lastRequestFailed = true;
                     return $q.reject(response);
                 });
             }
             return promise;
             }
         };
         }]
        );

})();

和测试

describe('SiteDescriptionService', function() {
'use strict';

describe('the service', function() {

    var service, httpBackend;

    beforeEach(module('application.service'));

    beforeEach(inject(function(_SiteDescriptionService_, $httpBackend) {
    service = _SiteDescriptionService_;
    httpBackend = $httpBackend;
    console.log(service);
    }));

    it('should be defined', function() {
    expect(service).toBeTruthy();
    });

});
});

干杯垫

看起来你在注入依赖时只使用了错误的名称，应该是＆＃39; SiteDescriptorService＆＃39;而不是＆＃39; SiteDescriptionService＆＃39;

另一个未知的提供商＆＃39;对于AngularJS服务
