如何修复beforeEachProviders（在RC4上弃用） [英] How to fix beforeEachProviders (deprecated on RC4)

问题描述

我刚刚将Angular2从RC3升级到RC4 ......

Ive just upgraded Angular2 from RC3 to RC4 ...

import {
  expect, it, iit, xit,
  describe, ddescribe, xdescribe,
  beforeEach, beforeEachProviders, withProviders,
  async, inject
} from '@angular/core/testing';

在我的单元测试中，我有以下代码......

In my unit test I have the following code ...

beforeEachProviders(() => [
    {provide: Router, useClass: MockRouter}
]);

这很好但是自从转到RC4后我在之前有一个弃用警告在beforeEachProviders之前。

This works fine but since moving to RC4 I have a deprecation warning on beforeEachProviders.

任何人都知道新的做事方式是什么？或者我应该从其他地方导入 beforeEachProviders 而不是'@ angular / core / testing'？

Anyone know what the new way of doing things is? Or should I import beforeEachProviders from somewhere else instead of '@angular/core/testing'?

推荐答案

您需要从@ angular / core / testing导入addProviders。

You will need to import addProviders from @angular/core/testing.

而不是：

beforeEachProviders(() => [
    {provide: Router, useClass: MockRouter}
]);

你想要这样做：

beforeEach(() => {
    addProviders([
        {provide: Router, useClass: MockRouter}
    ])
});
