Worked on the apache/hbase repository to refactor tests for the TableSnapshotInputFormat component, focusing on improving test clarity and maintainability. The approach involved updating assertions from Assert to assert for better readability and modifying snapshot name handling to derive directly from the test method name, ensuring alignment with evolving project requirements under HBASE-29968 Addendum. Leveraged Java, Hadoop, and JUnit-style unit testing to streamline the test suite, which reduced the risk of regressions in snapshot-related functionality and provided faster feedback in continuous integration. The work emphasized codebase consistency and adaptability to ongoing specification changes, without addressing major bug fixes.
