Modifying HTML elements using jsdom

When testing an angular controller within a large module, I encountered the "Controller is not a function" error. To fix this issue, I realized that I need to mock the DOM and set:

<html>

to

<html ng-app='myApp'>

by manipulating

document.documentElement.outerHTML

However, I faced a nomodificationallowederror

Is there a way to modify the tag using jsdom, specifically mocha-jsdom?

Answer №1

In case the element lacks a parent element, meaning it is the main element of the document, trying to modify its outerHTML property will result in a DOMException being thrown with the error code NO_MODIFICATION_ALLOWED_ERR. For more information, check out this article here.
