Tools for program testing?

[Choy Kho Yee]

Hi, to the experienced developers out there, I would like to know if
there are any tools that help in testing/debugging a program?
To be specific, what I need to know is which lines of the code have
been tested and which have not.

AFAIK, gdb is the standard tool for debugging and I am using it.
I heard that gprof is good for profiling where we can find which
functions have been called. Any other related tools recommendations?

Thanks.
