Fearless Dependency Upgrades

International PHP Conference – Spring Edition, Berlin

All software has dependencies: programming language, framework, and libraries. New versions for these dependencies with security fixes, bug fixes, or new features are regularly released. A new version is not always fully compatible with its predecessor. Teams that can rely on their test automation to answer the question of whether the new version of a dependency is problematic or not are in a good position.

This presentation shows best practices for upgrading dependencies without fear in projects that have high test coverage as well as approaches for projects without test automation.
