Automates C++ test creation, debugging, and coverage analysis using GoogleTest and CMake/CTest workflows.
This skill provides a comprehensive environment for managing the C++ testing lifecycle within Claude Code. It streamlines the implementation of GoogleTest and GoogleMock for C++17/20 projects, configures CMake/CTest for automated test discovery, and guides developers through a robust TDD loop. Beyond basic unit testing, it includes specialized patterns for diagnosing flaky tests, implementing memory and thread sanitizers (ASan/TSan), and generating detailed code coverage reports via gcov or llvm-cov to ensure production-grade software reliability.
