While few people question the value of test automation, comprehensive automated testing through the UI (the browser for web applications) is still uncommon in most software projects. Attempts often fail for three familiar reasons:

Difficult to learn — test scripts become complex and the tools are hard to master
Hard to maintain — UI tests break easily when the application changes
Long feedback loop — automated suites take too long to run

Success requires overcoming all three challenges.

This book shows a practical, battle-tested approach to implementing reliable UI test automation for web applications. You will learn:

Develop high-quality Playwright (Python) tests efficiently
Apply maintainable test design principles
Functional Testing Refactoring
Setting up a continuous testing server to run large suites of automated UI tests efficiently
Proven strategies for team collaboration and successful test-automation adoption across projects and organizations
