Nagarajan Pu developed comprehensive unit tests for the addToBlockBloomBothCases function in the siglens/siglens repository, focusing on validating bloom filter behavior for single words, multi-word phrases, and words containing spaces. Using Go and unit testing frameworks, Nagarajan designed scenarios to verify both addition and presence checks, ensuring the bloom filter logic handled diverse input cases reliably. This work increased test coverage and reduced the risk of regressions, supporting safer and faster deployments through improved CI validation. Although no bugs were fixed during this period, the depth of testing contributed to code quality, maintainability, and the overall reliability of the project.
