quick

quick aims to be a small header only library to help black box testing in C++. It borrows the idea from Golang's testing/quick package

Idea

Create a predicate where you want to test your struct/class/function/member function and return true on success. quick will randomly generate input data to this predicate and launch it predefined number of iterations or will keep running for predefined time duration.

Note

quick is in very alpha state not even remotely close to being ready for production

Example usage:

#include <iostream>
#include <string>

#include "quick.hpp"

using namespace std::chrono_literals;

std::string prefix(const std::string& s, int n)
{
  static int counter = 0;
  ++counter;
  return s.substr(0, n);
}

int main()
{
    auto f1 = [](const std::string& s, int n){
      const std::string ret = prefix(s, n);
      return ret == s.substr(0, n);
    };
    quick::check(f1, 200ms, "Prefix always has N length - 200ms");

    auto f2 = [](const std::string& s, int n){
      const std::string ret = prefix(s, n);
      return ret == s.substr(0, n);
    };
    quick::check(f2, 100, "Prefix always has N length - 100 iterations");
}
