Question

节日快乐！我遇到了一个我不知道为什么会出现的问题：

//登录控制：

angular.module('login.controller', [])

.controller('LoginCtrl', function($scope, $state, $translate, $ionicPopup, UserService, Auth) {

  // With the new view caching in Ionic, Controllers are only called
  // when they are recreated or on app start, instead of every page change.
  // To listen for when this page is active (for example, to refresh data),
  // listen for the $ionicView.enter event:
  //$scope.$on('$ionicView.enter', function(e) {
  //});

  // Form data for the login modal
  $scope.loginData = {};

  // Perform the login action when the user submits the login form
  $scope.doLogin = function() {

    var onSuccess = function(response) {
      if (response.data.user !== null) {
        Auth.setUser(response.data.user);
        Auth.setToken(response.data.user.token);

        $state.go('app.main');
      } else if (response.data.result == 101) {
        $ionicPopup.alert({
                   title: $translate.instant('login_error'),
                   template: $translate.instant('login_not_verified')
                 });
      }else {
        $ionicPopup.alert({
                   title: $translate.instant('login_error'),
                   template: $translate.instant('login_bad_password_text')
                 });
      }

    };

    var onError = function() {
      $ionicPopup.alert({
                 title: $translate.instant('login_error'),
                 template: $translate.instant('login_error_text')
               });
    };
    console.log('Doing login', $scope.loginData);

    UserService.login($scope.loginData.username, $scope.loginData.password).then(onSuccess, onError);

  };

  $scope.doRegister = function() {
    $state.go("register");
  };
});

//登录Ctrl测试

describe('LoginCtrl', function() {

  var controller,
      deferredLogin,
      userServiceMock,
      stateMock,
      scopeMock,
      ionicPopupMock;

  //Load the App module
  beforeEach(module('starter'));

  // Instantiate the Controller and Mocks

  beforeEach(inject(function($controller, $q, $rootScope, $translate, Auth) {
    deferredLogin = $q.defer();



    scopeMock = $rootScope.$new();

    // mock userServiceMock
    userServiceMock = {
        login: jasmine.createSpy('login spy')
                      .and.returnValue(deferredLogin.promise)
    };

    //mock $state
    stateMock = jasmine.createSpyObj('$state spy', ['go']);

    //mock $ionicPopup
    ionicPopupMock = jasmine.createSpyObj('$ionicPopup spy', ['alert']);

    //Instantiate LoginCtrl
    controller = $controller('LoginCtrl', {
      '$scope' : scopeMock,
      '$state' : stateMock,
      '$translate' : $translate,
      '$ionicPopup' : ionicPopupMock,
      'UserService' : userServiceMock,
      'Auth' : Auth
    });
  }));

  describe('#doLogin', function() {
    // Call doLogin on the Controllers
    beforeEach(inject(function(_$rootScope_) {
      $rootScope = _$rootScope_;
      controller.$scope.loginData.username = 'test';
      controller.$scope.loginData.password = 'password';
      controller.$scope.doLogin();

    }));

    it('should call login on userService', function() {
      expect(userServiceMock.login).toHaveBeenCalledWith('test','password');
    });

    describe('when the login is executed,', function() {
      it('if successful, should change state to app.main', function() {

        //TODO: Mock the login response from userService

        expect(stateMock.go).toHaveBeenCalledWith('app.main');
      });

      it('if unsuccessful, should show popup', function() {
        //TODO: Mock the login response from userService
        expect(ionicPopup.alert).toHaveBeenCalled();
      });
    });
  });
});

问题是当我执行测试时它执行expect(userServiceMock.login).toHaveBeenCalledWith('test','password');它给了我以下错误：

TypeError: undefined is not an object (evalating 'userServiceMock.login') in unit-tests/login.controller.tests.js（第 56 行）

我不知道 userServiceMock 给了我 undefined。

谢谢大家，如果您需要更多代码或其他内容，请告诉我。

这是我的因果报应：

问题是我没有在 test.conf 中包含翻译库，然后我没有从控制器中获取变量。
