Code coverage tools for C

Question

I am using CuTest for unit testing and would like to get information about code coverage. Are there any code coverage tools available for C?

Thanks

Answer 1

If you're using gcc, there is gcov. Compile your code with the -ftest-coverage -fprofile-arcs options, and without optomization. Then invoke gcov for each source source file. This will generate a .gcov file which contains the source code with the number of times each was executed.

Answer 2

GCC provides coverage functionality.

Answer 3

Our Test Coverage tools handles not only C in general but a variety of C dialects including GCC2/3/4, MS C in its many dialects, etc., as well as a number of other languages.

For C, it is often important that the tool be able to operate in embedded contexts with extermely low overhead. These tools do.
