Testing Distributed Systems with Pifpaf

Testing distributed systems often becomes a headache when you have to manually start, stop, and clean up external databases, message queues, and other background processes. This text-only course teaches you how to streamline your development and testing workflows using pifpaf, a powerful tool designed to manage temporary external services automatically. You will transition from writing fragile, custom shell scripts to using clean, declarative service management. What you'll learn: Understand core distributed systems testing concepts and service lifecycles; Configure and launch temporary external daemons like databases and message brokers; Write clean Python-based test suites that interface seamlessly with pifpaf; Implement modern testing practices including virtual environments and automated pytest integration; Troubleshoot and debug service startup failures and environment variable configurations. This course begins with foundational concepts of distributed architecture and local service dependency management, before guiding you through step-by-step practical implementation scenarios. Designed specifically for beginner to intermediate backend developers and QA engineers, this course requires only basic command-line familiarity and introductory Python knowledge.
