Selanne contributed to the ConvertX repository by building and refining a robust testing infrastructure for file conversion and processing tools. Over three months, Selanne expanded unit test coverage for modules handling image and document conversion, focusing on tools like LibreOffice, ffmpeg, and pandoc. Using TypeScript and Node.js, Selanne centralized test helpers, improved type definitions, and enhanced async test reliability, which reduced test flakiness and improved maintainability. The work included updating ESLint configurations and reorganizing test layouts to streamline onboarding and CI stability. This approach enabled safer feature delivery, faster iteration, and higher confidence in converter accuracy across the codebase.
