Worked on enhancing test reliability and continuous integration stability for the percona/percona-server-mongodb repository, focusing on network interface integration tests. Developed and integrated an ExpectedCounters struct in C++ to enable more flexible and readable counter comparisons within test assertions. Refactored existing assertion methods to utilize this new struct, which, along with increased timeouts, aimed to reduce test flakiness and improve overall test reliability. The work leveraged skills in C++, integration testing, and network programming, with an emphasis on test automation. No bugs were fixed during this period, but the feature contributed to more robust and maintainable automated testing workflows.
