Typemock Isolator++ For C/C++ Examples

Welcome to the official example repository for Typemock Isolator++, the most advanced mocking framework for C/C++.

This repository contains real-world and minimal examples that demonstrate how to write unit tests for hard-to-test C++ code, including global functions, constructors, legacy code, and inline and virtual methods, using Typemock’s native C++ engine.

🚀 About Typemock Isolator++

Typemock Isolator++ is a powerful mocking framework for C++ that enables complete isolation and mocking of any function, including those traditionally considered unmockable.

It allows you to:

• Mock global and static functions
• Control constructor behavior
• Intercept inline and virtual methods
• Test legacy code without modifying it
• Mock code in static libraries and external binaries
