🧪 single header unit testing framework for C and C++

Unity is a lightweight unit testing framework for C, providing the assertion library, test runner, and reporting mechanisms required to verify code correctness. It functions as core testing infrastructure for organizing and executing unit tests in C environments. The framework is designed for system-level and embedded software validation, with specific capabilities for verifying firmware and hardware drivers. It focuses on memory integrity and pointer validity, allowing for the validation of pointer states and the inspection of raw memory blocks. The toolset covers a broad range of compariso

microprofile is an embeddable profiler

C++ Benchmark Authoring Library/Framework

Simple, fast, accurate single-header microbenchmarking functionality for C++11/14/17/20

Schemathesis is a property-based testing tool and fuzzer for schema-based APIs. It analyzes OpenAPI and JSON Schema specifications to automatically generate test cases that identify crashes, schema violations, and validation bypasses. The project functions as a contract validator and security scanner, verifying that a live server strictly adheres to its defined specifications. The framework distinguishes itself through stateful API testing, which chains multiple related requests together to uncover bugs that only emerge during complex, multi-step user workflows. It also utilizes response-driv

Continuous Regression Testing for Engineering Teams

json-server is a development toolset used to simulate a full REST API from a JSON file. It functions as a customizable mock API server that allows for the simulation of CRUD operations and resource relationships without the need to write backend code. The project enables rapid prototyping by generating a fake backend that persists data changes back to a local JSON file. It distinguishes itself by providing a static asset file server to deliver local documents, images, and stylesheets alongside the mock API endpoints. The server includes capabilities for data querying, such as parameter-based

A unit testing framework for C

DebugView++, collects, views, filters your application logs, and highlights information that is important to you!

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

backward-cpp is a C++ stack trace library and debugging utility designed to capture, resolve, and print detailed execution traces and crash reports. It functions as a crash reporter and call stack printer that translates raw memory addresses into human-readable function names, filenames, and line numbers. The project provides automated crash reporting by registering system handlers for fatal errors, such as segmentation faults, to automatically generate execution traces upon program failure. It distinguishes itself by extracting source file fragments from disk to display specific lines of cod

gRPC benchmarking and load testing tool.

The reference C++ unit testing framework (TDD, xUnit, C++03/11/14/17)

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

Lightweight C++20 testing framework.

A C++ micro-benchmarking framework

A testing micro framework for creating function test doubles

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

Rest-assured is a Java-based REST API testing framework and HTTP client library designed for automating web service tests. It provides a fluent domain-specific language and assertion library to send HTTP requests and validate response metadata, including status codes, headers, cookies, and bodies. The framework is distinguished by a method-chaining DSL that creates readable specifications for API interactions. It features a filter-based request interception pipeline, object-mapping serialization for converting Java objects to JSON or XML, and a path-based parsing system to isolate specific fi

sds is a C dynamic string library that provides a memory management wrapper for heap-allocated strings. It implements binary-safe storage by tracking string lengths explicitly, allowing the library to handle null characters within data. The library distinguishes itself through a memory architecture that uses interchangeable function pointers for allocation and freeing, enabling the integration of custom memory managers. It utilizes header-stored length tracking to provide constant-time length retrieval and maintains null-terminated buffer padding to ensure compatibility with standard C string
