C++ Testing (Agent Skill)

Agent-focused testing workflow for modern C++ (C++17/20) using GoogleTest/GoogleMock with CMake/CTest.

When to Use

• 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

When NOT to Use

• 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
