説明
This is likely closely related to #543.
My mocha test suite runs after a setup script.
The problem is that examples fail silently if document.defaultView.XMLHttpRequest is assigned to global.XMLHttpRequest.
Similarly, I worked around it with
if (typeof global[property] === 'undefined' && property !== 'XMLHttpRequest') {
global[property] = document.defaultView[property];
}
I can't really pinpoint the root cause of this, but if nothing else it may be worthwhile to update the JSDOM guide.
