如何修复 beforeEachProviders(RC4 已弃用) [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，但自从迁移到 RC4 后，我在 beforeEachProviders 上收到了弃用警告.

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

有人知道新的做事方式是什么吗?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.

代替:

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

你会想要这样做:

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