CppUnit is a port of JUnit to C++, and was originally authored by Michael Feathers and Jerome Lacoste. Its basic architecture and usage closely follow the xUnit model. The implementation details differ from JUnit as a result of design choices by CppUnit’s developers and language differences between Java and C++. CppUnit’s implementation makes full use of advanced C++ language features, including templates, abstract classes, nested classes, and the Standard Template Library (STL) It also makes extensive use of C macros, which some consider inelegant and error-prone, but are definitely useful here. CppUnit is designed to be thread-safe.
