Worked on the intel/dml-language-server repository, focusing on a comprehensive refactor of the test suite to enhance reliability and maintainability. The approach involved reorganizing the test folder structure, moving test-related modules into a dedicated tests directory, and consolidating common testing utilities across various rules. By standardizing the test layout and centralizing utilities, the work improved code structure and test organization, making it easier for new contributors to onboard and for existing developers to maintain consistency. Implemented in Rust, these changes also contributed to a more reliable continuous integration process by clarifying test boundaries and streamlining the feedback loop for development.
