How to fix beforeEachProviders (deprecated on 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';

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

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

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

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

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

Instead of:

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

You'll want to do this:

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