By: Eran Kinsbruner

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.

The key pillars of a web application testing plan and strategy

In the first part of the book, we covered both the leading frontend test automation frameworks available for web developers, as well as the leading web application development frameworks. We learned that each development or testing framework comes with pros and cons. Knowing this upfront is an advantage, but this alone does not make up the main element within a testing strategy. These frameworks are the tools and, most likely, the enablers to drive a solid test plan from A to Z.

How and which tool to use needs to be driven by the testing plan and strategy itself, and to build such a plan, software leaders must rely on the core fundamentals of the testing pyramid matched to the product business requirements.

Let's start with the types of testing that any web application needs to undergo prior to being released to production. In Chapter 1, Cross-Browser Testing Methodologies, we covered the main web application...
