Bitesize Modern C++ : static_assert Posted on June 4, 2015 by Glennan Carnie C's assert library is a useful tool for catching invalid invariants (conditions that must hold true in order for your system to operate as specified) in your program. With catch break behavior enabled control-C will allow the currently running test to complete, and the test run will then end and report all the results so far. If it is false, the assertion fails: the program is halted, debug information is printed to USART2, and the status LED begins to throb (it’s noticeably different from blinking). Each unit test employs the use of C++ assert() to test the function results. Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. /* * Simple example of a CUnit unit test.

I take it you mean that a function written in C++ or C is exiting with a failed assertion. In this trivial example, the test will always pass. By testing the parts of a program first, and then testing the sum of its parts, integration testing becomes much easier; unit testing provides a sort of living documentation for the system. Test output is in XML or text format for automatic testing and GUI based for supervised tests. Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. The delete and new operators in C++ are much better than the malloc and free functions of C. The Boost Python Library is a framework for interfacing Python and C++.
