Explore a conference talk from Arch Conf 2020 that delves into generating test data for libalpm using Python. Learn about the pytest-pacman project, which creates local pacman and sync databases for testing pyalpm (the official Python libalpm bindings) without relying on pacman or internet data fetching. Discover the structure of pacman's local and sync databases, gain insights into writing a simple pytest plugin, and understand how pyalpm consumers can utilize this plugin. Access the project on GitLab and enhance your knowledge of Python-based testing for Arch Linux package management.
