Mix Tests and Production Code With Doctest...
summary
doctest is a single-header C++ test framework that actually ships a tiny interface and a separate implementation block so including it everywhere costs ~20 ms vs ~500 ms for Catch and you can remove all tests from release binaries with a compile-time flag. it auto-registers tests by initializing a global dummy that calls regTest, supports subcases and templated test cases, user-registered exception translators and lazy stringification, and its author reports 50,000 asserts compiling in under 10s in the fastest mode; CI covers ~300–400 builds.
