Repository of the month
catchorg/Catch2 — A modern, C++-native, test framework for unit-tests, TDD and BDD - using C++14, C++17 and later (C++11 support is in v2.x branch, and C++03 on the Catch1.x branch) Catch2 is a C++ testing framework designed for unit tests, TDD, and BDD. It simplifies writing tests by allowing natural syntax for test cases and assertions, eliminating the need for valid identifiers in test names. It also supports micro-benchmarking with explicit tags. Distinctively, it transitioned from a single-header library to a multi-header, compiled implementation in version 3.
