Additional information
Same issue as: #47310
Similar to that issue, I've run into this error when running tests that use JSDom:
- Save the following as "test.js":
/**
* @jest-environment jsdom
*/
"use strict"
global.window = {};
describe("test", () => {
it("runs", () => {
expect(1 + 1).toEqual(2);
});
});- Run
npm i jest jest-environment-jsdom - Run
npx jest
