@Meltem Demirkus Brandlmaier are you using a CI/CD pipeline for your code commits? Ideally, what you would setup is pipeline that would run various unit tests and other linting, debugging as you commit your PRs and merge requests. This way your code is tested at the time of commit. And, the benefit is, you keep up the velocity with development while the heavy lifting with testing is handled automatically. You can have your AI agent build you a pipeline that will call various tools for unit tests and pass or fail them based on your criteria.

@Richard Hancox Most of the big ones that we use in the home lab will detect the certificate expiration automatically. Traefik does this I know and probably Nginx as well. Also, make sure you are running the latest and greatest versions of your reverse proxy as they will likely build even better detection in aligned with current and upcoming defaults. I think the bigger ones are certbot schedules that ones may have setup via a scheduled task or CRON job will be more relevant to any changes.
