Traditional testing philosophy says things like
Test all subroutines
Test all branches of all conditions
Test the boundary conditions of all inputs
...
This is just big and scary and too much.
We're lazy, and we think we can still be effective with much
less work.
XP Testing
XP says to write your tests before you write your code.
It's hard enough to get people to write tests at all.
Changing their coding philosophy at the same time is worse.
If you can do Test First, excellent.
If you're not already testing, this is a chance to start some new
habits...
