How to mock useHistory hook in jest?

Question

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

Answer 1

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( );
