Worked on the containers/podman-py repository to enhance image build reliability and test coverage using Python and Docker. Developed default image build parameters and introduced integration tests to validate caching behavior, improving podman-remote compatibility and build determinism. Strengthened unit tests by addressing parameter defaults and correcting mock URL usage, which increased CI reliability. Focused on stabilizing integration tests by removing intermediary and external images, resolving deprecation warnings, and ensuring consistent image removal across test runs. Emphasized backend development and integration testing to reduce flakiness, accelerate feedback loops, and maintain a robust, maintainable test suite for continuous integration environments.
