Worked on enhancing the nf-core/modules repository by improving the robustness and reliability of the Verifybamid2 module. Focused on strengthening input suffix validation for reference files, which helps prevent misconfiguration and ensures data integrity in genomic workflows. Expanded test coverage to include empty input scenarios and updated test snapshots, reducing the risk of regressions and increasing confidence in future releases. Collaborated closely with other contributors to refine code quality and maintainability. Utilized Nextflow and bioinformatics testing practices throughout the process, demonstrating a disciplined approach to edge-case handling and test traceability within the context of genomic data processing modules.
