重定向URL ember-cli的验收测试

Question

我正在尝试通过验收测试，检查用户是否被重定向。当用户键入URL时，应将其重定向到另一个URL。有人可以告诉我为什么我在控制台上收到此错误？

ember.debug.js:30195 Error while processing route: account.contacts.index Cannot read property 'get' of undefined TypeError: Cannot read property 'get' of undefined

This is my route account/contacts/index.js
import Ember from 'ember';

export default Ember.Route.extend({
    redirect: function () {
        this.transitionTo('account.contacts.company');
    }

});

这是我的帐户/ contacts / index-test.js

moduleForAcceptance('Acceptance | /account/contacts/index');

test('visiting URL', function(assert) {
  visit('/account/contacts');
  andThen(function() {
    assert.equal(currentURL(), '/account/contacts/company');
  });
});

在我的测试中，这就是我得到的：

Expected:"/account/contacts/company"
Result: "/account/contacts"
