CppUTest

Automatically detects leaks using platform-specific mechanisms (e.g., MS debug heap) or overridden new/delete operators, crucial for embedded systems where resource management is critical, as detailed in the README's memory leak section.

Allows custom functionality via TestPlugin classes, enabling checks for system stability and resource cleanup beyond standard tests, evidenced by the example main with plugin installation.

Provides comprehensive macros like CHECK_EQUAL and DOUBLES_EQUAL for various data types, reducing boilerplate and simplifying test writing, as listed in the assertion macros section.

Supports Unix, Windows, and MacOS with multiple build systems (Make, CMake, vcpkg, Conan), making integration straightforward for diverse environments, shown in the getting started and Conan/CMake examples.
