Angular 4 TestBed compileComponents

Question

I have an angular 4 project which is inspired from angular cli. With angular 4.1.x everything works fine (run, build, unit tests, isolated component tests).

But when i move to ^4.2.0 which installs 4.4.6 , i get the following issue described below. This actually starts from version 4.2.2.

Taking the simplest case -

The component code is

import { Component } from '@angular/core';

@Component({
  selector: 'gen-test',
  templateUrl: './gen-test.component.html',
  styleUrls: [ './gen-test.component.css' ],
})
export class GenTestComponent {

}

And the test is as simple as

import { TestBed, async } from '@angular/core/testing';

import { GenTestComponent } from '../gen-test.component';

fdescribe('GenTestComponent', () => {

    beforeEach(async(() => {
        TestBed.configureTestingModule({
            declarations: [ GenTestComponent ],
        })
        .compileComponents();
    }));

    it('should run', ()=> {
       // todo: write test
    });
});

Even for this code when run a npm test it gives me the following error

Failed: fn$$1 is not a function
    TypeError: fn$$1 is not a function
