During June 2025, Stéphane Decisy focused on improving the reliability of UI test automation for the PrestaShop/autoupgrade repository. He addressed recurring memory-related failures by increasing the Docker memory limit to 1024M before executing upgrade simulations, which stabilized test runs and reduced flakiness in the continuous integration pipeline. Stéphane utilized his expertise in CI/CD, Docker, and PHP configuration, applying shell scripting to automate resource adjustments and enforce consistent test environments. This targeted bug fix enhanced the predictability of release readiness and improved feedback loops for upgrade workflows, demonstrating a thoughtful approach to infrastructure tuning and test automation reliability.
