IntersectionObserver is not defined

[Leila-ad]

Hi I used the Taiga UI editor and I can't fix unit test error "IntersectionObserver is not defined".... I have read https://taiga-ui.dev/testing/jest this page and tried it and instead it gives me "jest worker encountered 4 child process exceptions, exceeding retry limit" error. :( how can I fix it
Thank you in advance

In your file:

Don't forget

import 'jest-preset-angular/setup-jest';
import '@ng-web-apis/universal/mocks';

window.IntersectionObserver = function () {
  this.observe = () => {};
  this.unobserve = () => {};
  this.disconnect = () => {};
};

In our docs

I believe @ng-web-apis/universal/mocks contains that mock for IntersectionObserver. If not, we should add it.

I did that but then it gives another error. did you try it?
