Developed a comprehensive server testing suite for the bitcoin-sv/arc repository, focusing on the Blocktx server’s core methods to enhance backend reliability. Leveraging Go and gRPC, the work introduced targeted tests for CurrentBlockHeight, Health, and ClearBlocks, utilizing mocks to isolate server logic and ensure accurate validation of interactions with message queues and storage components. The Health tests specifically addressed message queue connection status and timestamp handling, improving observability and runtime monitoring. This effort established robust quality gates, enabling earlier detection of regressions and reducing production risk, while laying a scalable foundation for future test expansion and ongoing backend development.
