Catch2 is a comprehensive framework for C++ software validation, providing an environment for unit testing, integration verification, and performance analysis. It enables developers to define and execute automated test suites and micro-benchmarks directly within their applications. The framework is distinguished by its header-only distribution, which allows for integration into existing build systems without requiring complex external dependencies. It utilizes a hierarchical section-based execution model that supports behavior-driven testing, allowing for shared setup and teardown logic acros

CppUTest unit testing and mocking framework for C/C++

Hippomocks

C++ Benchmark Authoring Library/Framework

C++ mocking made easy. A simple yet very expressive, headers only library for c++ mocking.

Fortio is a performance testing tool written in Go that generates constant request rates to measure latency histograms and response percentiles. It functions as a network performance benchmarker for analyzing system performance across HTTP and gRPC endpoints, and includes a specialized HTTP echo server for mirroring requests. The project distinguishes itself through a web-based HTTP load testing API used for triggering asynchronous tests and visualizing result data through graphs. It also provides server behavior simulation, allowing the echo server to inject artificial delays and vary respon

This project is a performance measurement framework and microbenchmarking library designed for C++ and Python. It provides a toolset for measuring the execution time of small code fragments using high-resolution timers, calculating statistical aggregates, and analyzing asymptotic complexity. The framework distinguishes itself through specialized capabilities for multithreaded performance testing, using synchronized execution to measure parallel throughput. It includes mechanisms to prevent compiler optimizations from removing benchmarked code and supports complex parameterization via Cartesia

This project is a comprehensive C++ unit testing framework designed to verify code logic and identify regressions through a suite of assertion macros, test fixtures, and execution runners. It automates the discovery and registration of test cases during static initialization, allowing developers to define isolated test environments that ensure repeatable and predictable conditions for every execution. The framework distinguishes itself through a sophisticated mock object library that enables the simulation of components and the enforcement of strict interaction requirements. By intercepting v

Microcks is a platform for turning your API and microservices assets - OpenAPI specs, AsyncAPI specs, gRPC protobuf, GraphQL schema, Postman collections, SoapUI projects - into live mocks in seconds.

doctest is a unit testing framework and assertion library for C++ delivered as a single-header library. It provides a test runner with a command line interface to execute tests, filter test suites, and generate execution reports. The framework supports in-source unit testing and allows for the complete removal of testing logic from compiled binaries via preprocessor stripping to eliminate performance overhead in production environments. It also enables cross-binary test registry sharing, allowing one executable to utilize the test runner of another. Capabilities include parameterized testing

Microbenchmarking for Modern C++

A C++ library for debugging purposes that can print any variable, even user-defined types.
