So, now I want to do a little quiz about
identifying testable features. Let's consider
this simple problem called printSum.
We won't see the implementation because we are doing black-box
testing. And all we need to know is that printSum takes
two integers, a and b, and prints the sum of
these two numbers. So what I want to ask, is
how many independently testable features do we have here? Do
we have one, two, three features? Or more than three features?
