如何使用 typescript 为反应测试库设置智能感知

Question

I just downloaded Create-React-App which uses react testing library. I do not get intellisense when I use it's methods (Example: toBeInTheDocument). How to set intellisense? Do we have any type definitions for RTL?

import React from 'react';
import { render } from '@testing-library/react';
import App from './App';

test('renders learn react link', () => {
  const { getByText } = render(<App />);
  const linkElement = getByText(/learn react/i);
  expect(linkElement).toBeInTheDocument();
});

Answer 1

You need to import '@testing-library/jest-dom'
