User List Debugging Example

This example demonstrates common debugging scenarios in frontend JavaScript, specifically focusing on user list rendering with intentional bugs and their solutions.

  1. userList.js - demonstrate an error caused by an index out of bounds issue — run the userList.test.js unittest to see
  2. taskManager.js - demonstrate error due to a global variable being overwritten - run taskManager.test.js unittest to see

Prerequisites

  • Node.js 14.x or higher
  • A modern web browser with developer tools
  • Basic understanding of DOM manipulation

Setup and Running

  1. Install dependencies:

    npm install

  2. Run the application:

    npm start

Testing

To run all tests:

npm test

To run individual tests:

npx jest tests/userList.test.js
npx jest tests/taskManager.test.js

You can also run tests with a specific pattern:

npx jest --testNamePattern="loadDashboard should render user list correctly"
