I'm running require('jsdom-global')() on my setup.js jest file and also inside the file that i using jsdom
I also tried to write my own code and it worked for jest but didn't work from some reason on my production server.
const { JSDOM } = require('jsdom');
const jsdom = new JSDOM('<!DOCTYPE html><html><head></head><body></body></html>');
const { window } = jsdom;
function copyProps(src, target) {
const props = Object.getOwnPropertyNames(src)
.filter(prop => typeof target[prop] === 'undefined')
.map(prop => Object.getOwnPropertyDescriptor(src, prop));
Object.defineProperties(target, props);
}
global.window = window;
global.document = window.document;
global.navigator = {
userAgent: 'node.js',
};
copyProps(window, global);
I will keep investigate this issue just wonted to point that out and see if there is a quick fix for this issue. thanks,
Apparently jest already comes with jsdom preconfigured. So if you remove your jsdom-global import (or handwritten JSDOM setup), everything should work, plus the error message should be gone.
