During July 2025, Enric Balletbo i Serra modernized the FIT signature testing documentation for the flipperdevices/u-boot repository, focusing on transitioning the workflow from a legacy shell script to a pytest-based approach. He updated reStructuredText documentation to guide developers in using pytest with sandbox configuration, clarifying explicit test commands and setup steps to improve reproducibility and onboarding. By removing references to the older vboot_test.sh script, Enric streamlined the testing process and reduced maintenance overhead. His work demonstrated skills in technical documentation and testing, delivering clearer guidance for contributors and supporting a more maintainable, Python-driven testing infrastructure for the project.
