In the software development domain, test automation has emerged as the cornerstone of delivering reliable applications. This comprehensive guide provides a systematic roadmap for designing and implementing test automation frameworks that transcend tool-specific limitations, ensuring they adapt and endure. You will learn to apply core software architectural principles—including modularity, loose coupling, and layering—to your test code. The book offers practical guidance on managing test data, orchestrating parallel test executions, and integrating seamlessly with CI/CD pipelines using quality gates. Furthermore, it details how to expand your framework's capabilities to include non-functional testing, such as security, performance, and resilience.
