Invariant failed: You should not use <Route> outside a <Router>

I solved this problem by changing:

import {Route, Switch} from "react-router";

import {Route, Switch} from "react-router-dom";

import React from 'react';import ReactDom from 'react-dom';import Header from '../components/Header/Header';import { BrowserRouter } from 'react-router-dom';it('renders Header without crashing', () => {  const div = document.createElement('div');  ReactDom.render(    <BrowserRouter>      <Header />    </BrowserRouter>,   div);  ReactDom.unmountComponentAtNode(div);});
