Ada refactored the testing infrastructure for the linebender/vello repository, focusing on improving how snapshot and generated images are managed during test runs. She reorganized test directories and separated reference snapshots from generated outputs, segmenting them by CPU and GPU to streamline visual comparisons. This restructuring, implemented in Rust and leveraging her skills in file system operations and testing, enhanced the maintainability and reliability of the test suite. By laying the groundwork for Kompari integration, Ada enabled more efficient visual regression testing and simplified onboarding for new contributors. Her work addressed test complexity and improved continuous integration workflows within the project.
