Worked on the nf-core/methylseq repository to enhance pipeline testing by introducing a dedicated test case for the bwameth aligner’s mem2 indexing mode. Developed and integrated the 'bwameth_mem2' test within the bwameth_variants.nf.test suite, utilizing Nextflow and the nf-core test framework to ensure comprehensive validation of the mem2 functionality. This addition expanded test coverage for the bwameth variant path, reducing the risk of regressions related to mem2 support. Demonstrated skills in bioinformatics, pipeline testing, and Git version control while maintaining clear commit documentation. The work improved confidence in the pipeline’s reliability for mem2-related features.
