• Catch

  57 18,820 8.9 C++

  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)

  

  The code uses catch2 to test for correctness and performance. Catch2 is a unit testing framework for C++, but it also provides basic micro-benchmarking features. Unfortunately, it doesn't provide any way to visualise the results, so I created a script and submitted PR adding plotting capabilities to Catch.

• range-v3

  20 4,148 6.1 C++

  Range library for C++14/17/20, basis for C++20's std::ranges

  rangesv3 - Uses ranges-v3 - range library for C++14/17/20. Pretty close to the implementation using std::ranges, but a bit more complex, because it distinguishes between actions and views. This method uses the reverse action with views and to_vector, which might allocate an extra vector.

• flux

  7 537 9.3 C++

  A C++20 library for sequence-orientated programming (by tcbrindle)

  fluxranges - Uses flux, a C++20 library for sequence-oriented programming. Quite noisy compared to other range implementations.
