react router4 跳转怎么实现

[事在人为2018]

let React = require('react');
let ReactDOM = require('react-dom');

import Test1 from "./Test1.jsx";
import Test2 from "./Test2.jsx";

import { BrowserRouter, HashRouter, Switch, Route, Link } from 'react-router-dom'

let router =
    <HashRouter>
        <div>
            <Switch>
                <Route path="/test1" component={Test1}></Route>
                <Route path="/test2" component={Test2}></Route>
            </Switch>
        </div>
    </HashRouter>

ReactDOM.render(router, document.getElementById('root'));

比如有个条件:为1时自动跳转到Test1，为2时自动跳转到Test2
