Automated Testing Framework

Overview

This README provides insights into the selection of the testing framework cypress for our usecase, and highlights the advantages and disadvantages of using Cypress over Playwright.

Tool Comparison: Cypress vs. Playwright

Cypress

Advantages

  1. Ease of Setup and Use: Cypress offers a highly intuitive setup with minimal configuration. It is perfect for teams wanting to get started quickly.
  2. Real-Time Test Runner: Cypress provides an interactive test runner with time travel debugging, letting you see step-by-step actions and easily debug.
  3. Automatic Waiting: Built-in automatic waits for DOM elements to appear, reducing the need for manual wait commands.
  4. Focus on Frontend Testing: Optimized for testing frontend applications with great support for frameworks like Vue, React, and Angular.
  5. Built-In Assertions: Cypress provides built-in commands and assertions tailored for frontend testing, which reduces reliance on additional libraries.
  6. Extensive Documentation and Community: Cypress has been around longer, providing more comprehensive resources and community-driven plugins.

Disadvantages

  1. Limited Browser Support: Cypress mainly supports Chrome, Edge, and Firefox. It does not support Safari or WebKit out-of-the-box, limiting cross-browser testing.
  2. No Native Mobile Emulation: Cypress does not offer native mobile browser testing or mobile device emulation.
  3. Limited Multi-Tab Support: Cypress has some restrictions on handling multiple tabs or windows during testing.
  4. Not Ideal for Backend Testing: While Cypress can make API requests, it is mainly designed for frontend, UI-centric tests.

Playwright

Advantages

  1. Multi-Browser Support: Playwright supports Chrome, Edge, Firefox, and WebKit, including testing on Safari and mobile browsers.
  2. Advanced Control: Playwright provides granular control over browser contexts, making it ideal for more complex scenarios like handling multiple tabs, downloads, and network events.
  3. Mobile Emulation: Native support for mobile device emulation and testing on real mobile browsers.
  4. Cross-Platform and Multi-Context: Can run tests in parallel across different browser environments, making it suitable for more diverse test scenarios.

Disadvantages

  1. Steeper Learning Curve: Playwright offers more flexibility but requires more configuration and setup compared to Cypress.
  2. No Interactive Test Runner: Unlike Cypress, Playwright does not have a built-in interactive GUI for running and debugging tests in real-time.
  3. Manual Wait Handling: Playwright requires more explicit wait commands in test scripts for certain actions, which can make tests more prone to timing issues.

Why Cypress Was Chosen for This Project

Cypress was chosen for testing for several key reasons:

  1. Focus on Frontend Testing: The primary goal of this project is to test the UI and user workflows (e.g., registration, login, purchasing), where Cypress excels. Its UI-centric design makes it an ideal fit for this type of testing.

  2. Ease of Setup and Debugging: Cypress provides a quicker setup and more intuitive debugging experience with its real-time test runner. This is essential for rapid iterations and easier identification of issues, especially during the 5-day testing phase.

  3. Automatic Waiting: Since the website has dynamic content and user interactions, Cypress’ automatic waiting features reduce the need to manage timeouts and manual waits, improving test reliability.

  4. Simplified Assertions and DOM Interaction: Cypress’ built-in commands and assertions make it easy to write tests that interact with the DOM and verify UI states without requiring external libraries.

  5. Large Community and Ecosystem: Cypress has extensive documentation, plugins, and a large community, making it easier to find support and resources for any testing-related questions or problems.

While Playwright is a powerful tool with broader browser support and advanced control features, the simplicity, ease of debugging, and frontend focus of Cypress made it the best fit for testing the user-centric features of the given exercise.
