Model-Based Testing to Help You Enhance Your Agile Testing Process
0 likes699 views
This document discusses how model-based testing can help enhance an agile testing process. It provides an overview of agile principles and popular agile methods like Scrum and XP. It also discusses challenges in testing during each iteration and how model-based testing involves generating test cases from a behavioral model of the system. The document demonstrates modeling the behavior of a FOREX trading application and generating tests to cover new requirements introduced in an iteration. It argues that model-based testing fits well with agile values by facilitating collaboration, responding faster to changes, and increasing test coverage.
