Is this a regression?

Not sure

Description

These two commands:

schematics blank --schematics --name=schematics
ng build schematics

Result in this:

The angular/cli doesn't generate ,spec schematics correctly.

This fixes the error:

import { Tree } from '@angular-devkit/schematics';
import { SchematicTestRunner } from '@angular-devkit/schematics/testing';
import * as path from 'path';

const collectionPath = path.join(__dirname, '../collection.json');


describe('schematics', () => {
  it('works', async() => {
    const runner = new SchematicTestRunner('schematics', collectionPath);
    const tree = await runner.runSchematicAsync('schematics', {}, Tree.empty());
    tree.subscribe(tree=>{
      console.log(tree);
      expect(tree.files).toEqual([]);
    });
      
  });

});

🔬 Minimal Reproduction

 
schematics blank --schematics --name=schematics
ng build schematics

Creates a new schematic in current folder.
Subsequent build produces this error.

🔥 Exception or Error

 src/schematics/index_spec.ts:12:25 - error TS2339: Property 'runSchematic' does not exist on type 'SchematicTestRunner'.
