cli-testing-library

CLI Testing Library 是 Testing Library 的配套函式庫，旨在模擬 Testing Library 的 API 來測試 CLI 應用程式。

npm

npm install --save-dev cli-testing-library

Yarn

yarn add --dev cli-testing-library

import {resolve} from 'path'
import {render} from 'cli-testing-library'

test('Is able to make terminal input and view in-progress stdout', async () => {
  const {clear, findByText, queryByText, userEvent} = await render('node', [
    resolve(__dirname, './execute-scripts/stdio-inquirer.js'),
  ])

  const instance = await findByText('First option')

  expect(instance).toBeInTheConsole()

  expect(await findByText('❯ One')).toBeInTheConsole()

  clear()

  userEvent('[ArrowDown]')

  expect(await findByText('❯ Two')).toBeInTheConsole()

  clear()

  userEvent.keyboard('[Enter]')

  expect(await findByText('First option: Two')).toBeInTheConsole()
  expect(await queryByText('First option: Three')).not.toBeInTheConsole()
})
