mock lodash debounce in jest

test.js

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

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

Thank you so much, this worked for me.

jest.mock('lodash.debounce', () => jest.fn(fn => fn))

This works , Thanks

This worked for me wonderfully

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

Thanks.

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;
  },
}));

👍

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...
