TESTING IN THE SERVERLESS ERA: NAVIGATING THE CHALLENGES OF MODERN CLOUD ARCHITECTURE

This comprehensive article examines the evolving landscape of serverless computing, particularly focusing on testing challenges and quality assurance strategies. The article explores how the serverless paradigm transforms cloud computing while presenting unique testing challenges for Software Development Engineers in Test (SDETs). Through analysis of multiple studies and real-world implementations, this article investigates key areas, including dynamic environment management, event-driven complexity, asynchronous operations, and CI/CD integration. The article reveals critical metrics across various platforms, showing that serverless architectures offer significant cost reduction and operational efficiency benefits. However, they also introduce complex testing scenarios with considerable cold start variations across different runtimes. It presents empirical data on function execution success rates, resource utilization patterns, and recovery metrics, providing a framework for understanding and addressing the unique quality assurance requirements in serverless environments. The findings demonstrate that organizations must adapt their testing strategies to address environment consistency, event handling, and performance optimization challenges while leveraging the benefits of automated scaling and resource management. This article contributes to the growing knowledge of serverless computing by offering practical insights and methodologies for implementing effective testing strategies in modern cloud architectures.
