mock lodash debounce in jest

test.js

// somewhere on top
import _ from 'lodash';
jest.unmock('lodash');

// then
_.debounce = jest.fn((fn) => fn);

Updated version of @mos-adebayo's above that worked for me (using lodash-es)

jest.mock('lodash-es', () => ({
  ...jest.requireActual('lodash-es'),
  debounce: (fn) => {
    fn.cancel = jest.fn();
    return fn;
  },
}));

You have to call the function and ignore the timer jest.mock('lodash/fp/debounce', () =>jest.fn((nr, fn) => fn())). This worked for me.

This worked for me perfectly:

import * as lodash from 'lodash-es';
// other imports...

jest.mock('lodash-es/debounce', () => ({
  default: jest.fn(fn => fn),
  __esModule: true
}));

// describe block...
