- license:
- MIT
- compatibility:
- C11 baseline. Tools: CMake/CTest or Make. Debugging: gdb/lldb (Linux/macOS), MinGW gdb + objdump (Windows), MSVC dumpbin + WinDbg (Windows). Optional: sanitizers (Clang/GCC), fuzzing (libFuzzer/AFL where supported).

C Testing
Pragmatic workflow for reliable C tests and bug-finding.
When to activate
- Adding unit tests for C functions
- Building a small test harness around a module
- Debugging failing tests or memory corruption
- Enabling sanitizers or fuzzing to reproduce crashes
Core rules
- Keep unit tests deterministic and isolated.
- Avoid real network/time in unit tests.
- Run ASan/UBSan in CI for memory and UB signal.
