Tests for resizing window fails for Node.js v7 while working fine for v4-v6 #10660

componentDidMount() {
    window.addEventListener('resize', this.handleResize);
  }

  componentWillUnmount() {
    window.removeEventListener('resize', this.handleResize);
  }

 it('resize event is attached on componentDidMount', () => {
    window.addEventListener = spy();

    const component = mount(<TextField options={["aa", "ab"]} />);

    expect(window.addEventListener.calledOnce).to.equal(true);
  });

it('resize event removed attached on componentWillUnmount', () => {
    window.removeEventListener = spy();

    component.detach();

  });
