Facts

What it does
RapidCheck is a C++ framework for property-based testing that generates random test data to find counterexamples to properties.github.com · 30 Sept 2026
Shrinking
When a property fails, RapidCheck tries to find the smallest failing test case and displays it as a counterexample.github.com · 30 Sept 2026
Property checks
Properties are implemented as callables passed to rc::check, and RapidCheck repeatedly calls them with generated inputs.github.com · 30 Sept 2026
Generators
RapidCheck includes generators for common types and combinators for building custom generators.github.com · 30 Sept 2026
STL support
Built-in arbitrary-value generation supports types including vectors, maps, sets, tuples, pairs, strings and chrono types.github.com · 30 Sept 2026
Integrations
The README lists integrations with Boost Test, Google Test and Google Mock.github.com · 30 Sept 2026
Catch integration
RapidCheck also documents basic integration with the Catch test library.github.com · 30 Sept 2026
