5 best C++ Functional testing libraries in 2025

Functional testing is a type of software testing, which verifies that each function of the software application operates in conformance with the requirement specification. C++ libraries are basically a collection of functions that can be reused repeatedly in programs. Most of the libraries use object-oriented programming principles and some of them are written in C language. In this kit, we'll list some of the best C++ libraries that can be used for testing purpose: oovaide - C and Java automated analysis, class, component and sequence UML diagramming IDE tool, test coverage, complexity, duplicate code, analysis statistics; cpp-project-template - A simple template for C++ projects: CMake, Unit tests, Continous Integration all set up and ready to go.
