Pairwise Testing: An Easy Guide to Orthogonal Arrays & All-Pairs Combinations

One of the testing challenges we face is how to handle the large numbers of test cases we sometimes need to create and execute. We can't test everything, but pairwise testing using orthogonal arrays or an all-pairs algorithm can help generate pair combinations that reduce the number of test cases we run while still finding a large percentage of bugs.

Navigating the Installation

If you've ever popped a CD into a drive and run an install for software you're about to test, then you might be performing installation testing indirectly. If not properly installed, an application could give false results for all other testing. A better strategy is to test the install process directly, which will give you greater confidence in the quality of your software.

Know What's at Stake

Everyone knows the importance of well-defined functional requirements. We want our products to work, don't we? But how many of us are paying as much attention to defining our non-functional requirements? In this historically focused feature, we learn from past mistakes the potentially disastrous results of inadequately tested NFRs.

The Case of the Missing IF

Grandma cooked her roast a certain way, and now you're repeating the process without knowing why you have to trim the ends off an uncooked roast even though the pan is adequately sized. Relic processes in many organzations fall trap to this mindset since the reason behind the action lost its meaning long ago. Lee Copeland calls these "IF ..., THEN ..." processes. When the organization loses sight of the IF responsible for the action, then you're left with what Lee describes as "a process without a context; a rule without a reason."

What Goes Up Must Come Down

Writing requirements purely top-down or only bottom-up is risky to say the least. The devil's in the details, and those details are likely to be missed when working from a single direction. What if you could tackle your requirements from both directions by incorporating use cases and user centered design? Learn how balancing your approach to writing requirements can result in more detailed, pragmatic documentation.
