Question

我的服务是：

myApp.service('userService', [
  '$http', '$q', '$rootScope', '$state', '$cookies', '$base64', function($http, $q, $rootScope, $state, $cookies, $base64) {
    var user;
    user = {};

    this.logout = function() {
      user = {};
      delete $cookies.userAccessKey;
      return $state.transitionTo('login');
    };
  }
]);

我想编写单元测试以确保$cookies.userAccessKey已删除。我怎样才能做到这一点？在我这样做的同时，我如何确保将user设置为空？

要检查用户是否为空，只需添加公共getter或checker：

myApp.service('userService', [
  '$http', '$q', '$rootScope', '$state', '$cookies', '$base64', function($http, $q, $rootScope, $state, $cookies, $base64) {
    var user;
    this.user = {}; // or a method this.isLoggedIn() for more security

    this.logout = function() {
      this.user = {};
      delete $cookies.userAccessKey;
      return $state.transitionTo('login');
    };
  }
]);

然后，在你的测试中：

describe('logout', function(){
    beforeEach(function(){
        userService.login(); //relog before each test
    });

    it('should remove the userAccessKey from cookie', function() {
        userService.logout();

        inject(function($cookies) {
          expect(cookies.userAccessKey).toBeUndefined();
        });
    });

    it('should reset user object', function() {
        userService.logout();

        expect(userService.user).toEqual({});
        });
    });
});

如何测试AngularJS服务中是否设置了$ cookie？
