Worked on the pingcap/tidb repository over three months, focusing on improving the reliability and maintainability of backend test suites. Developed and standardized a brief explain format for planner-related tests, omitting non-functional plan IDs to enhance readability and reduce test flakiness. Applied these changes across integration, planner, and MPP test suites, using Go and SQL to streamline test output and accelerate pull request validation. Addressed a bug in MPP test enforcement by normalizing output, which improved CI stability and feedback speed. The work emphasized robust database development, effective use of testing frameworks, and careful management of database test infrastructure.
