Make src/cdk/testing folder classes importable

Bug, feature request, or proposal:

Make src/cdk/testing folder classes importable

What is the expected behavior?

All classes under src/cdk/testing should be importable, as in: import { wrappedErrorMessage } from '@angular/cdk';

What is the current behavior?

Can’t import src/cdk/testing content

What are the steps to reproduce?

import { wrappedErrorMessage } from '@angular/cdk'; will error out

Providing a Plunker (or similar) is the best way to get the team to see your issue. Plunker template: https://goo.gl/DlHd6U

What is the use-case or motivation for changing an existing behavior?

Build a set of components and their unit tests using @angular/cdk

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

2.0.0-beta.8

Is there anything else we should know?

No

Yeah, as @DevVersion mentioned, we don’t intend these to be public right now. We would want to be much more deliberate in designing what our testing utilities would look like for consuming developers.

[devversion]

Right now, the testing utilities are intentionally not exposed in the public API.

At some point there was the idea of exposing those utilities to the public using a secondary entry-point (similar as for @angular/core/testing)

Meaning that developers can import those utilities like that:

import {XX} from '@angular/cdk/testing';
