Mocking moment timezone in Jest for React.js

To mock moment and handle timezones in Jest for React.js unit tests, you can use a library like jest-mock-date combined with jest.fn().

Below are the steps to mock moment and date in Jest:

  1. Install jest-mock-date library:

    bash
  2. Create a manual mock for moment in your Jest setup file (e.g., setupTests.js):

    javascript
  3. Use jest.mock('moment-timezone') in your test files before importing moment:

    javascript
  4. Write your test cases with mocked moment:

    javascript

By following these steps, you should be able to mock moment and handle timezones in Jest for your React.js tests effectively.
