snitch

Snitch guarantees no heap allocations from the framework itself, enabling precise tracking of test code memory usage, as emphasized in the README's comparison with Catch2.

Compiles template-heavy tests significantly faster than Catch2 and doctest, with benchmarks showing up to 50% reduction in build times for real-world test suites.

Supports constexpr and consteval testing with dedicated macros like CONSTEXPR_CHECK, leveraging C++20 features for compile-time validation.

Works with CMake, Meson, and vcpkg, and can be used as a regular library or header-only, providing adaptability for different project setups.
