Flaky-claw
Worked on stabilizing the TiDB test suite in the pingcap/tidb repository, focusing on reducing flakiness and improving CI determinism for backend Go systems. Over two months, addressed reliability issues in server, session, and TiFlash-related test infrastructure by refining session management, assertion strategies, and memory control. Enhanced test harnesses to better handle garbage collection, CRR simulations, and partition timing, resulting in more deterministic test outcomes and faster PR validation. Leveraged Go’s concurrency and debugging capabilities to deliver robust test coverage, enabling more reliable nightly builds and increasing developer productivity by minimizing intermittent failures and CI noise across core components.
