How to mock useHistory hook in jest?


I am using UseHistory hook in react router v5.1.2 with typescript? When running unit test, I have got issue.

TypeError: Cannot read property ‘history’ of undefined.

import { mount } from 'enzyme';
import React from 'react';
import {Action} from 'history';
import * as router from 'react-router';
import { QuestionContainer } from './QuestionsContainer';

describe('My questions container', () => {
    beforeEach(() => {
        const historyHistory= {
            replace: jest.fn(),
            length: 0,
            location: { 
                pathname: '',
                search: '',
                state: '',
                hash: ''
            action: 'REPLACE' as Action,
            push: jest.fn(),
            go: jest.fn(),
            goBack: jest.fn(),
            goForward: jest.fn(),
            block: jest.fn(),
            listen: jest.fn(),
            createHref: jest.fn()
        };//fake object 
        jest.spyOn(router, 'useHistory').mockImplementation(() =>historyHistory);// try to mock hook

    test('should match with snapshot', () => {
        const tree = mount(<QuestionContainer />);


Also i have tried use jest.mock('react-router', () =>({ useHistory: jest.fn() })); but it still does not work.


I needed the same when shallowing a react functional component that uses useHistory.

Solved with the following mock in my test file:

jest.mock('react-router-dom', () => ({
  useHistory: () => ({
    push: jest.fn(),
