Testing C/C++ source code

Unit Testing C Code

This is something I've been wondering now that we have to use C/C++ as base language for some of our university projects :

In Java there's JUnit,

In PHP there's PHPUnit

etc.

How are unit testing done in C/C++? This is probably a silly question, but I don't think I ever read exactly how applications (source code) are unit tested--if there's even such a thing in C/C++--other than "check if the code compiles".

Answer 1

Boost has an excellent unit test library.

Answer 2

cppunit is what we use.

Answer 3

There are quite a few frameworks but to name a few:

• http://code.google.com/p/googletest/
• http://cpptest.sourceforge.net/

Some people will just role their own using #ifdefs and a single test.c or test.cpp file:

#ifdef TEST_1
int main(int argc, char** argv) { /*test code for 1*/ }
#endif

#ifdef TEST_2
int main(int argc, char** argv) { /*test code for 2*/ }
#endif

At compile time a you can generate the test by defining TEST_x (where x is a number) this generates executables for each test. Maybe not ideal but very simple.

Answer 4

I've used CxxTest and CppUnit and found CxxTest to be easier to use (it automates generating some of the skeleton code - on the downside it needs Python installed) and lightweight (no libraries, entirely header based).

Answer 5

We use cunit:

http://cunit.sourceforge.net/

It allows one to logically (or functionally) group tests, produce test output in XML format for automated publishing of results, etc.

Answer 6

anther one is UnitTest++. Header-only, lightweight and simple operation, yet does everything needed.
