During April 2025, Sunlisten Guo developed a Docker-based local testing environment for the AutoMQ/automq repository, focusing on streamlining local development and testing workflows. Leveraging Docker, Docker Compose, and shell scripting, Sunlisten created an integrated setup featuring LocalStack, AWS CLI, controller, and broker services. The solution included automated environment preparation and startup scripts, enabling developers to quickly provision and orchestrate services for end-to-end local testing. This approach improved onboarding efficiency and reduced setup time, allowing for more repeatable and reliable feature validation. The work demonstrated depth in CI/CD and local development practices, though the focus remained on feature delivery.
