Run into a problem using mocha tests with jsdom, delete window.propertyName; doesn't work. So after this command window.propertyName is still defined. So my tests failed. I have workaround use window.propertyName = undefined; which works fine, but I expected to use delete keyword.

This is an issue with jsdom. window comes from jsdom's document.defaultView. Unfortunately I can't help you with this :\

You can replicate this issue by:

var jsdom = require('jsdom')
var html = '<!doctype html><html><head><meta charset="utf-8"></head><body></body></html>'

var document = jsdom.jsdom(html)
var window = document.defaultView

window.lol = 2
delete window.lol
console.log(window.lol)  // => 2

@rstacruz thanks, I agree, going to close this one and open another one on jsdom repo.
