In addition to the Template Unit Test Framework (TUT) and Google Test (gtest), Grail42 Core now includes an adapter to normalize the use and output of CppUTest. Since the point of the three adapters is to normalize the API and output of these C++ unit testing frameworks, the examples of usage and output provided on this post are relevant to CppUTest as well as TUT and gtest.
My next task is to add a template project to Grail42 Templates that starts each of the unit test frameworks on a separate thread while capturing their output and then serializes the output to stdout. That template will enable creating a number of 3 threaded unit tests to used in the process of creating a new C++ unit testing framework that is thread safe.
