CLI Testing Library

Simple and complete CLI testing utilities that encourage good testing practices.

Installation

This module is distributed via [npm][npm] which is bundled with [node][node] and should be installed as one of your project's devDependencies:

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

Usage

This is currently the only section of "usage" documentation. We'll be expanding it as soon as possible

Usage example:

const {resolve} = require('path')
const {render} = require('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()
})

While this library does work in Windows, it does not appear to function properly in Windows CI environments, such as GitHub actions. As a result, you may need to either switch CI systems or limit your CI to only run in Linux
