Service- and Component-based Development: Using Select Perspective™ and UML

Test case specification from an interaction diagram

White-box tests are prepared by using the interaction diagrams as abstract program scripts. Each interaction diagram shows how the classes, component interfaces, and other items of interest interact to provide the behavior described in the use case courses. Given the interaction diagram and a set of pre- and post-conditions to constrain the test, the precise pattern of interaction that should occur can be predicted and documented. When the code is executed, the pattern of code execution can be confirmed against the script provided.
