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 />);

        expect(tree).toMatchSnapshot();
    });
});

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(),
  }),
}));

This one worked for me:

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

Here's a more verbose example, taken from working test code (since I had difficulty implementing the code above):

Component.js

  import { useHistory } from 'react-router-dom';
  ...

  const Component = () => {
      ...
      const history = useHistory();
      ...
      return (
          <>
              <a className="selector" onClick={() => history.push('/whatever')}>Click me</a>
              ...
          </>
      )
  });

Component.test.js

  import { Router } from 'react-router-dom';
  import { act } from '@testing-library/react-hooks';
  import { mount } from 'enzyme';
  import Component from './Component';
  it('...', () => {
    const historyMock = { push: jest.fn(), location: {}, listen: jest.fn() };
    ...
    const wrapper = mount(
      <Router history={historyMock}>
        <Component isLoading={false} />
      </Router>,
    ).find('.selector').at(1);

    const { onClick } = wrapper.props();
    act(() => {
      onClick();
    });

    expect(historyMock.push.mock.calls[0][0]).toEqual('/whatever');
  });

Wearing my politician hat I'll dare to state that you're asking the wrong question.

It's not useHistory that you want to mock. Instead you'd just want to feed it with history object which you control.

This also allows you to check for push invocations, just like the 2 top answers (as of writing this).

If that's indeed the case, createMemoryHistory got your back:

import {Router} from 'react-router-dom'
import {createMemoryHistory} from 'history'

test('QuestionContainer should handle navigation', () => {
  const history = createMemoryHistory()
  const pushSpy = jest.spyOn(history, 'push') // or 'replace', 'goBack', etc.
  render(
      <Router history={history}>
        <QuestionContainer/>
      </Router>
  )
  userEvent.click(screen.getByRole('button')) // or whatever action relevant to your UI
  expect(pushSpy).toHaveBeenCalled()
})

In github react-router repo i found that useHistory hook uses singleton context, when i started use in mount MemoryRouter it found context and started works. So fix it

import { MemoryRouter } from 'react-router-dom';
const tree =  mount(<MemoryRouter><QuestionContainer {...props} /> </MemoryRouter>);

A way to mock the push function of useHistory:

import reactRouterDom from 'react-router-dom';
jest.mock('react-router-dom');

const pushMock = jest.fn();
reactRouterDom.useHistory = jest.fn().mockReturnValue({push: pushMock});

Then, how to check if the function have been called:

expect(pushMock).toHaveBeenCalledTimes(1);
expect(pushMock).toHaveBeenCalledWith('something');

This works for me, I was having problems with useLocation too

jest.mock('react-router-dom', () => ({
  useHistory: () => ({
    push: jest.fn()
  }),
  useLocation: jest.fn().mockReturnValue({
    pathname: '/another-route',
    search: '',
    hash: '',
    state: null,
    key: '5nvxpbdafa'
})}))

I found the above answers very helpful. However I missed the ability to spy and actually test functionality. But simply naming the mock function first solved that for me.

const mockPush = jest.fn();
jest.mock('react-router-dom', () => ({
  useHistory: () => {
    const push = () => mockPush ();
    return { push };
  },
}));
