AngularJS和UI-Router：在angularjs单元测试期间'错误：过渡被取代'

Question

我正在尝试为我的项目创建授权包。我在单元测试中遇到了“转换已取代”错误，但我找不到实际的位置。

单元测试：

import angular from 'angular';
import 'angular-mocks';
import worldManagerApp from '../../src/world-manager-app';
import security from '../../src/security/security';

const {inject, module} = angular.mock;

describe('LoginService', ()=> {
    let $httpBackend;
    let $rootScope;
    let successHandler;
    let errorHandler;
    let LoginService;

    const USER = {username: "TEST", password: "PASSWORD"};

    beforeEach(function() {
        module(worldManagerApp);
        module(security);

    });

    beforeEach(inject((_$httpBackend_, _LoginService_, _$rootScope_) => {
        $httpBackend = _$httpBackend_;
        $rootScope = _$rootScope_;
        LoginService = _LoginService_;

        successHandler = jasmine.createSpy('successHandler');
        errorHandler = jasmine.createSpy('errorHandler');
    }));

    it('should exist', () => {
        expect(LoginService).toBeDefined();
    });

    describe('.login()', () => {

        describe('when given a proper username and password', () => {
           it('should return the username and success', () => {
               $httpBackend.expectPOST('/login').respond(200, {user: USER});
               LoginService.login("TEST", "PASSWORD");
               $rootScope.$digest();
               $httpBackend.flush();

               expect($rootScope.currentUser).toEqual("TEST");
           });
        });
    });

});

服务：

export default function LoginService($http){
    'ngInject';

    let service = {};
    service.login = login;

    function login(username, password){
        $http({
            url:'/login',
            method: 'POST',
            data: {
                username: username,
                password: password,
            },
        }).then (function(response) {
            response.username;
        }).catch(function(response){
        });
    }

    return service;
}

错误：

PhantomJS 1.9.8 (Windows 8 0.0.0) LoginService .login() when given a proper username and password should return the username and success FAILED

我认为这是一个ui-router问题，但是如果我做错了，我无法弄清楚它应该如何工作。

从1.5.9角度更新到1.6.1版本后，我遇到了同样的问题，可以通过以下方式更新依赖项来解决：

npm update angular-ui-router

旧版本0.3.1会导致错误，而在更新版本0.3.2中，我的应用程序可以再次正常运行（现在使用角度1.6.1）。
