The record

What it does: RapidCheck is a C++ framework for property-based testing that generates random test data to find counterexamples to properties.
Shrinking: When a property fails, RapidCheck tries to find the smallest failing test case and displays it as a counterexample.
Property checks: Properties are implemented as callables passed to rc::check, and RapidCheck repeatedly calls them with generated inputs.
Generators: RapidCheck includes generators for common types and combinators for building custom generators.
STL support: Built-in arbitrary-value generation supports types including vectors, maps, sets, tuples, pairs, strings and chrono types.
Integrations: The README lists integrations with Boost Test, Google Test and Google Mock.
Catch integration: RapidCheck also documents basic integration with the Catch test library.
Build requirements: RapidCheck uses CMake and requires a C++11-compliant compiler; the README lists Clang 3.5, GCC 4.9 and Visual Studio 2015 as CI compiler versions.
Test defaults: A property passes by default after 100 successful tests, and the number is configurable.
Limitations: The user guide says it is a work in progress, and the API has not stabilized and may change at any time.
License: The project is distributed under a BSD 2-Clause license.
Purpose: RapidCheck is a C++ framework for property-based testing inspired by QuickCheck and similar frameworks.
Test generation: It generates random test data to search for inputs that falsify a property.
Counterexamples: When it finds a failing case, RapidCheck tries to shrink it to a smaller counterexample.
