cpp-testing

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): - 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 - Large-scale refactors unrelated to test coverage or failures - Performance tuning without test regressions to validate - Non-C++ projects or non-test tasks - TDD loop : red → green → refactor (tests first, minimal fix, then cleanups). - Isolation : prefer dependency injection and fakes over global state. - Test layout : tests/unit , tests/integration , tests/testdata . - Mocks vs fakes : mock for interactions, fake for stateful behavior. - CTest discovery : use gtest_discover_tests() for stable test discovery.
