Developed a comprehensive unit test suite for the gofr-dev/gofr repository, focusing on the gRPC observability interceptors to enhance test coverage and reliability. The work involved designing and implementing tests in Go that validated interceptor behavior across successful executions, error scenarios, and multiple stream types. By emphasizing observability and robust unit testing practices, the contribution improved the reliability of the grpc package and reduced the risk of regressions. No major bug fixes were addressed during this period, as the primary focus was on quality assurance and preparing the codebase for future continuous integration workflows using Go and gRPC technologies.
