Scalable Test Automation with Playwright: Build frameworks that scale and move beyond quick starts to enterprise-grade automation

Modern web automation requires more than just scripting; it demands a transition from basic interaction to enterprise-grade engineering. Playwright has emerged as a premier tool for this shift, offering robust support for both UI and API testing. However, scaling these capabilities for complex environments requires the application of rigorous software engineering principles to ensure frameworks remain resilient, efficient, and adaptable to evolving business needs.

This book bridges the gap between basic automation and sophisticated architectural design. You will explore foundational patterns like Page Object Model, Factory, and Singleton, alongside core principles such as SOLID and DRY. The book provides a step-by-step guide to building modular, tool-agnostic frameworks, covering critical topics like CI/CD integration, test data management, and observability. It even addresses high-level challenges, such as migrating between tools like Playwright and Puppeteer.

By the end of this book, you will gain the competency to design and scale automation frameworks suited for enterprise environments. You will move beyond the role of a scripter to become a test architect, capable of leading the development of future-proof, maintainable, and highly scalable testing solutions.

What you will learn

● Master POM, Factory, Singleton, and Template Method for scalable frameworks.

● Apply SOLID and DRY principles to architect decoupled automation codebases.

● Execute seamless Playwright to Puppeteer migrations via advanced class abstraction.

● Orchestrate dynamic test data using Faker libraries and environment-specific configurations.

● Detailed explanations, practical code examples, and a real-world testing tool migration exercise.

● Integrate GitHub Actions and GitHub Pages for automated gates and reporting.

● Set a practical footprint in the AI testing landscape.
