Open-source alternatives to Hippomocks

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

Continuous Regression Testing for Engineering Teams

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

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

A unit testing framework for C

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

A testing micro framework for creating function test doubles

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

Automated API Testing and Quality Assurance

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 C++ micro-benchmarking framework

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

C++ Benchmark Authoring Library/Framework

gRPC benchmarking and load testing tool.

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

microprofile is an embeddable profiler

Lightweight C++20 testing framework.

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

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

The XCTest Project, A Swift core library for providing unit test support

Runs a load test on the selected URL. Fast and easy to use. Can be integrated in your own workflow using the API.

Apache JMeter is a Java-based performance testing tool and multi-protocol traffic simulator used to analyze the stability and scalability of servers and networks. It functions as a distributed load testing framework that coordinates remote worker nodes from a single controller to generate high volumes of concurrent traffic. The project is distinguished by its ability to simulate traffic across diverse backend systems, including HTTP, JDBC, LDAP, JMS, FTP, and TCP. It provides a headless command-line interface for automated execution and a reporting system that transforms raw sample logs into
