Cristi Corcoveanu focused on improving test reliability for the mx-chain-go repository, addressing flaky behavior in the RequestHandlerStub component. By introducing a WaitGroup to synchronize asynchronous code, Cristi ensured more deterministic test outcomes and reduced CI feedback times. The work involved cleaning up test logs by removing unnecessary debug print statements and reverting superfluous imports and formatting changes to maintain core stub behavior. Utilizing Go and leveraging skills in concurrency, unit testing, and debugging, Cristi’s contributions targeted the stabilization of critical test infrastructure. This effort enhanced the reliability of releases by minimizing test flakiness and streamlining the continuous integration process.
