Worked on the ProteoWizard/pwiz repository to enhance test suite reliability by developing the DiskSpaceTest feature, which checks available disk space before running automated tests. This addition aimed to reduce flaky failures caused by insufficient environment resources, with the disk space threshold refined from 20GB to 15GB for greater flexibility. Output readability was improved by displaying bytes and percentages, making diagnostics clearer for developers. The feature was temporarily disabled during ongoing refactoring to maintain CI stability. The work involved C#, CI/CD pipelines, and unit testing, reflecting a focus on robust software testing practices and careful integration with existing continuous integration workflows.
