Optimizing test design using tools: saving time, increasing detection probability, reducing number of testsMartedì 20 Giugno

Many test engineers study and get certified, but rarely use the test design techniques that they have been taught. I found it strange, but then realized that testers like to use tools, and if techniques were implemented via tools, they would have used them more.

Pairwise and Classification Trees are very good and efficient techniques for test design, prioritization of tests, and for saving time and money on performing the right tests first.

In this workshop, I shall present the techniques, and the tools (mostly freeware) one may  exercise in projects right after the training.

Hands-on exercises will be performed throughout the workshop to exercise participants in using the techniques via the tools. We shall install the tools at the beginning of the day, as an exercise as well.

Workshop objectives

The objectives of this workshop is to give the participants a practical overview of

  • What is Pairwise and Orthogonal Arrays?
  • How to analyze parameters for optimization?
  • How to use the freeware ‘allpairs’ tool by James Bach, in your projects
  • How to use the freeware ‘PICT’ tool by Microsoft (for pairwise), in your projects
  • What is Classification Trees?
  • How to use the classification Trees/Testona Editor tool in your projects?

The course emphasizes the implementation of the techniques using the freeware tools that will be provided. Through presentation, discussion, debate, brainstorming, questioning, and hands-on exercises - we shall learn how to implement those techniques in our projects.


Testers, testing team leaders and test managers, that would like to know these very efficient techniques for optimizing test design and their practical implementation, using proven tools (open source, free, commercial).


Participants should have basic testing knowledge about testing life cycle, testing techniques and methods, test measurements.

Note: Class participants should have laptops/PC, with Windows 7/8/10, internet and email access and Office 2010 and up. Tools shall be provided and installed during the workshop as an install exercise at the beginning of the day.
