Overview of this book

Testing web applications during a sprint poses a challenge for frontend web app developers, which can be overcome by harnessing the power of new, open source cross-browser test automation frameworks. This book will introduce you to a range of leading, powerful frameworks, such as Selenium, Cypress, Puppeteer, and Playwright, and serve as a guide to leveraging their test coverage capability. You’ll learn essential concepts of web testing and get an overview of the different web automation frameworks in order to integrate them into your frontend development workflow. Throughout the book, you'll explore the unique features of top open source test automation frameworks, as well as their trade-offs, and learn how to set up each of them to create tests that don't break with changes in the app. By the end of this book, you'll not only be able to choose the framework that best suits your project needs but also create your initial JavaScript-based test automation suite. This will enable fast feedback upon code changes and increase test automation reliability. As the open source market for these frameworks evolves, this guide will help you to continuously validate your project needs and adapt to the changes.

Guidelines for picking a web development framework

When picking a web development framework, frontend developers must consider the following:

  • Features and differentiating abilities of the framework against the user stories at hand
  • Rapid development abilities with fewer coding requirements
  • Vast community support (open source benefits)
  • Simplified debugging
  • Learning curve
  • Consistent performance
  • Reusability of application components
  • Built-in security features of the framework
  • Misc: Built-in dev tools (DOM snapshots), plugin-friendly, app layout design, support for the TypeScript language, accessibility support

The previously mentioned development frameworks vary by their age, features, community, and suitability for the application types that are being built. It is nice to see how these frameworks have trended throughout the years based on Stack Overflow questions (https://insights.stackoverflow.com/trends?tags=angular%2Creactjs%2Cjquery...
