"unit"_test: Implementing a Macro-free Unit Testing Framework from Scratch in C++20
summary
Claim: a working macro-free C++20 framework is implemented from scratch that makes the shown snippet compile and run. It uses C++20 features — modules concepts source_location plus new lambda and UDL tricks — to provide tests, suites, sections, BDD, matchers and a parallel runner as a single header single module delivery. Benchmarks show faster compile and run vs. common frameworks; results include cross‑compiler support (works on four compilers, MSVC 2019 with caveats) and published code on GitHub.
