”Automated Add on Extension Testing” by Spencer Magnusson, for Blender Conference 2025
Add-on extensions grow bigger and more diverse with every Blender update. From running operators to drawing the user interface, from installation to backwards compatibility, there is much to test before releasing add-ons and their updates. This presentation will give add-on developers the tools to dramatically simplify testing and releasing workflows.
