# Antithesis C++ SDK This library provides methods for C++ programs to configure the [Antithesis](https://antithesis.com) platform. It contains three kinds of functionality: * Assertion macros that allow you to define test properties about your software or workload. * Randomness functions for requesting both structured and unstructured randomness from the Antithesis platform. * Lifecycle functions that inform the Antithesis environment that particular test phases or milestones have been reached. For general usage guidance see the [Antithesis C++ SDK Documentation](https://antithesis.com/docs/using_antithesis/sdk/cpp/overview/)
