我有一個(gè)像這樣的超級簡單的反應(yīng)應(yīng)用程序。索引.tsx應(yīng)用程序.tsx主要.tsx主頁.tsx索引.tsximport React from 'react';import ReactDOM from 'react-dom';import './index.css';import App from './App';import { BrowserRouter as Router } from "react-router-dom";import { ApolloProvider } from "react-apollo";import client from "./utils/client";ReactDOM.render(  <Router>    <ApolloProvider client={client}>      <App />    </ApolloProvider>  </Router>,  document.getElementById('root'));應(yīng)用程序.tsximport React from 'react';import Main from "./Main";function App() {  return (    <Main />  );}export default App;主要.tsximport React from 'react';import { Switch, Route, Link } from "react-router-dom";import Home from "./Home";const Main:React.FC = () => {    return (        <div>            <Switch>                <Route exact path='/' component={Home} />            </Switch>        </div>    );};export default Main;主頁.tsximport React, {useContext} from 'react';import { Link } from "react-router-dom";const Home:React.FC = () => {    return (        <div>            <h1>Home</h1>            <Link to='http://google.com'> Google</Link>        </div>    );};export default Home;    我有一個(gè)帶有虛擬測試的 App.test.tsx 來運(yùn)行它。import React from 'react';import { render, screen } from '@testing-library/react';import App from './App';test('renders learn react link', () => {  render(<App />);  expect(true).toBeTruthy});如果我用yarn test我得到一個(gè)錯(cuò)誤：不變失?。耗悴粦?yīng)該<Link>在 a 之外使用<Router>我擁有的鏈接被Home.tsc包圍<Router>在index.tsx我在這里做點(diǎn)事。該應(yīng)用程序運(yùn)行沒有任何錯(cuò)誤。此錯(cuò)誤僅在我運(yùn)行測試時(shí)出現(xiàn)
