Tests for resizing window fails for Node.js v7 while working fine for v4-v6 #10660
Description
Version: v7.4.0
Platform: Linux filo 4.8.0-30-generic #32-Ubuntu SMP Fri Dec 2 03:43:27 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
For my react-autocomplete-input package some tests are failing now. For node.js versions 4+ everything works fine as you can see. I updated all packages to the latest versions and it didn't help.
I am testing if my component reacts on window resize action.
Component Code
componentDidMount() { window.addEventListener('resize', this.handleResize); } componentWillUnmount() { window.removeEventListener('resize', this.handleResize); }Failing tests code
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(); const component = mount(<TextField options={["aa", "ab"]} />, { attachTo: document.body.getElementsByTagName('div')[0] }); component.detach(); expect(window.removeEventListener.calledOnce).to.equal(true); }); /* Output 1) resize resize event is attached on componentDidMount: AssertionError: expected undefined to equal true at Context.<anonymous> (test/AutoCompleteTextField.spec.js:524:51) 2) resize resize event removed attached on componentWillUnmount: AssertionError: expected undefined to equal true at Context.<anonymous> (test/AutoCompleteTextField.spec.js:534:54) */Packages involved:
- "chai": "^3.5.0",
- "chai-enzyme": "^0.5.1",
- "cheerio": "^0.20.0",
- "enzyme": "^2.4.1",

Updating those packages to the latest versions didn't help :/
