How to fix this error [Vue warn]: Unknown custom element: <nuxt-link> in unit testing with Jest

Question

I have a problem running the npm run test. The error is

 [Vue warn]: Unknown custom element: <nuxt-link> - did you register the component correctly? For recursive components, make sure to provide the "name" option.

SidebarCMS.spect.js

import { shallowMount } from "@vue/test-utils";
import SidebarCMS from "../layouts/SidebarCMS";

const factory = () => {
  return shallowMount(SidebarCMS, {});
};

describe("SidebarCMS", () => {

  test("renders properly", () => {
    const wrapper = factory();
    expect(wrapper.html()).toMatchSnapshot();
  });
});

Can anyone help me?

You can stub the child components while creating instance. For more information about stubbing components, check out this link.

Try like this, This will resolve your warning!.

const factory = () => {
  return shallowMount(SidebarCMS, {
     stubs: {
      'nuxt-link': true,
      'any-other-child': true
     }
   });
};
