I've tried to install new jsdom package. It wasn't worked but after some research, I found some helper package. https://www.npmjs.com/package/happy-dom

It should work I think I will do it tomorrow.

The issue is more complicated. We need to implement our test system on Karma. There isn't another software to Unit Test Web Components. So it looks like one week of work to configure all environment. For this reason, I'll switch to make DE work not only in DEMO mode instead of it.
