The fundamental rule for testing functions requires that every function be tested in an already fully tested and debugged program. How can this be accomplished?

a) Impossible! The main function must have all the functions it calls attached to get it to compile and run properly. b) The main function is tested with stub functions replacing each` function. c) Write drivers for the stub functions to test them. d) Add each non-stub function in turn for testing. e) Write drivers for the function implementations one at a time to test them independently.
