I previously asked for suggestions on teaching testing in C++. Based
on some of the replies I received I decided that best way to proceed
would be to teach the students how they might write their own unit
test framework, and then in a lab session see if I can get them to
write their own. To give them an example I've created the following
UTF class (with a simple test program following). I would welcome and
suggestions on how anybody here feels this could be improved:

A fool with a tool is still a fool. The challenge in testing is not test
management, but designing test cases to cover the possible failures in
the code under test. That's something that most developers don't do
well, because their focus is on getting the code to run.

Unless the test are written first!

You can't do coverage analysis or any other form of white-box testing on
code that hasn't been written. There is a big difference between a
tester's minset and a develper's mindset, and it's very hard for one
person to do both.
