Worked on enhancing the reliability and test coverage of critical macros in the Esri/abseil-cpp repository, focusing on ABSL_RAW_DCHECK and ABSL_RAW_DLOG. Developed and released comprehensive tests in C++ to verify correct compilation, runtime behavior, and expected termination in debug builds. The approach included covering both success and failure paths, as well as debug logging scenarios, to ensure robust macro guarantees. Emphasized thorough testing and suite reliability, enabling earlier detection of regressions and safer releases. Utilized C++ development and testing skills to strengthen release quality and reduce risk for downstream users relying on these foundational macro utilities.
