Modern C++ testing workflow using GoogleTest/GoogleMock with CMake/CTest integration. Agent-focused testing workflow for modern C++ (C++17/20) using GoogleTest/GoogleMock with CMake/CTest. Follow the RED → GREEN → REFACTOR loop: Prefer target-level settings instead of global flags. GCC + gcov + lcov: Clang + llvm-cov: Only use if the project already supports LLVM/libFuzzer or a property-testing library. Minimal libFuzzer harness (pseudocode: replace ParseConfig): - Covers unit and integration test design with TDD red-green-refactor loop, fixtures, mocks, and fakes for dependency isolation - Includes CMake/CTest configuration with automatic test discovery via gtest_discover_tests() and filtering strategies - Provides coverage setup for GCC (gcov/lcov) and Clang (llvm-cov), plus sanitizer configuration (ASan, UBSan, TSan) for memory and race detection - Documents flaky test prevention patterns, debugging workflows, and common pitfalls like global state, sleep-based synchronization, and over-mocking - Writing new C++ tests or fixing existing tests - Designing unit/integration test coverage for C++ components - Adding test coverage, CI gating, or regression protection - Configuring CMake/CTest workflows for consistent execution - Investigating test failures or flaky behavior - Enabling sanitizers for memory/race diagnostics - Implementing new product features without test changes...
