Question

这是我的代码

 function guestDeviceManagerController(guestService, status) {
   vm.initState = function() {
     guestService.isUserAdmin(status.standardId).then(function(isAdmin) {
       vm.isAdmin = isAdmin;
       vm.template = vm.isAdmin ? vm.templates[0] : vm.templates[1];
     }, function() {
       //TODO: display user error
     });
   };
   vm.initState();
 }

我想知道如何模仿这些请求以及它应该在SpyOn（）中完成的位置，如果是这样的话，我需要测试将响应返回为false和true。

进行了以下修改：

describe('guestDeviceManagerController Tests', function() {
  'use strict';
  var scope,
    controller,
    statusService,
    guestService,
    q;


  beforeEach(function() {
    module('mainApp');
    module('mobileDevicesModule');

    inject(function($rootScope, $controller, $q, _statusService_, _guestService_) {
      scope = $rootScope.$new();
      statusService = _statusService_;
      guestService = _guestService_;
      q = $q;

      controller = $controller('guestController', {
        $scope: scope,
        guestService: guestService
      });
    });

  });



  it('Assert view that should render for admin', function() {

    spyOn(guestService, 'isUserAdmin').and.returnValue(q.when(true));
    scope.$apply();
    controller.initState();

    expect(controller.template.url).toEqual('app/mobile-devices/guest/admin/guest.html');
  });


});

现在收到以下错误：错误：意外请求：GET http://localhost:34327/guest//IsAdmin

使用true isAdmin结果测试成功路径：

spyOn(guestService, 'isUserAdmin').andReturn($q.when(true));

使用false isAdmin结果测试成功路径：

spyOn(guestService, 'isUserAdmin').andReturn($q.when(false));

测试错误路径：

spyOn(guestService, 'isUserAdmin').andReturn($q.reject());

阅读$q documentation。

请务必致电$rootScope.$apply()以实际解决/拒绝承诺。

例如：

// spy the service:
spyOn(guestService, 'isUserAdmin').andReturn($q.when(true));
// instantiate the controller:
$controller('guestDeviceManagerController');
// resolve/reject the promises. This will cause the callback functions to be called
$rootScope.$apply();
// now test that the callback has done what it's supposed to do

我如何使用AngularJs模拟测试then（）对Jasmine的响应
