In our inaugural One Key Idea session, we looked at how use pairwise testing to examine combinations of inputs, configuration values, types of data, and the like. This is a great technique when the interaction between these factors is unpredictable. However, in some cases, specific business rules govern these interactions. How can we model these business rules and use that model to develop a reasonable set of tests? Simple: decision tables. In this One Key Idea session, Rex will explain the basics of this fundamental technique. In twenty minutes or less, you’ll learn how to create and use these straightforward, table-based representations of business logic in your daily work.
