This project is not affiliated with the "Testing Library" ecosystem that this project is clearly inspired from. We're just big fans :)

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();
});

For a API reference documentation, including suggestions on how to use this library, see our documentation introduction with further reading.

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
