Mock Screen Wake Lock API (navigator.wakeLock) with ease and run your tests using Jest

🏠 Homepage

Prerequisites

Install

npm i -D jest-wake-lock-mock
# or
yarn add -D jest-wake-lock-mock

Usage

In your jest.config.js or package.json under jest section create a setupFiles array and add jest-wake-lock-mock to it.

{
  setupFiles: ['jest-wake-lock-mock'],
  // jest config...
}

Tests

Write your tests with confidence using the same Screen Wake Lock API api as in the browser.

Example (More):

const requestWakeLock = async () => {
  try {
    const wakeLock = await navigator.wakeLock.request('screen');

    return { wakeLock };
  } catch (error) {
    return { error };
  }
};

test('wakeLock request with success', async () => {
  const { wakeLock, error } = await requestWakeLock(handleRelease);

  expect(error).not.toBeDefined();
  expect(wakeLock).toBeDefined();
  expect(wakeLock?.type).toEqual('screen');
  expect(wakeLock?.released).toBe(false);
});
