Design Driven Testing for Systems

Written by 
Design Driven Testing (DDT) for software was first outlined in the book Use Case Driven Object Modeling with UML: Theory and Practice (by Doug Rosenberg and Matt Stephens), and then described in detail in Design Driven Testing: Test Smarter, Not Harder by the same authors.

DDT is a highly methodical approach to testing, allowing you to know when you’ve finished – i.e. when you’ve written enough tests to cover the design and the requirements. It helps you to “zoom in” and write algorithmic tests to cover intensive or mission‐critical sections of code, and to know when it’s safe to “zoom out” and write fewer tests for boilerplate or less critical code.
In this Article, Doug extends the concept of DDT for hardware/software systems, allowing SysML‐based designs to be tested in a highly rigorous, systematic way. It’s still Design Driven Testing, but now the design elements that need to be tested include all of the “four pillars of SysML”, whereas DDT for software focuses on testing behavior.

ICONIX (Chief Executive Officer)
 
Doug Rosenberg founded ICONIX in his living room in 1984 and began training companies in object-oriented analysis and design around 1990. ICONIX specializes in JumpStart training for UML and SysML, and offers both onsite and open-enrollment courses.
 
Doug developed a Unified Booch/Rumbaugh/Jacobson approach to modeling in 1993, several years before the advent of UML, and began writing books around 1995. Design Driven Testing is his 6th book on software engineering. He’s also authored numerous multimedia tutorials (including Enterprise Architect for Power Users) and several eBooks, including Embedded Systems Development with SysML.
 
Doug has spent the last few years doing "deep dive" consulting into cutting-edge technology including cross-platform mobile app development, REST APIs, and NoSQL databases, and gaining first-hand experience on some "hardcore agile" projects of varying sizes.  He's also been working with dozens of graduate students at the University of Southern California Center for Systems and Software Engineering (USC CSSE), managing Directed Research projects and developing/piloting the Resilient Agile process.
