Worked on the PRQL/prql repository to enhance integration testing and improve CI workflows over a one-month period. Focused on updating the integration test snapshot format for greater consistency and readability, which aids in maintaining reliable test results. Introduced Docker Hub login steps within the CI pipeline to streamline container management, leveraging Docker and YAML for configuration. Enhanced error handling in Rust-based integration tests, enabling faster debugging and reducing investigation time for developers. These changes collectively improved test reliability and maintainability, supporting quicker release cycles and contributing to a more efficient development process for the PRQL project’s ongoing evolution.
