The Power of TestCase-Design II

In Part 2 of the Power of TestCase-Design, we take a closer look at the character of equivalence classes and how it influences combinations. We learn about invalid equivalence classes and straight throughs (also known as happy paths), and how combining invalids with straight throughs allows you to maintain maximum probability while getting to the position where they are handled by the application. We also consider boundary values, an often overlooked aspect of testing, which like invalids, are not appropriate to test specific values of other attributes.
