Smarter Test Design with Classification Trees and Pairwise Techniques

In many teams, the total number of possible combinations of inputs, outputs, browsers, and devices for the software we need to test has grown to an alarming number. As testers, we need to choose the most important tests first, but how do we do that without understanding the potential scope in the first place? In this tutorial, Julie Gardiner will share two powerful testing techniques that can help us be more efficient and effective with our testing. Classification trees are a structured, visual approach to identifying test objects and documenting test ideas and data in a way that allows anyone to understand and quickly build test cases. Pairwise is a powerful test technique that can give you a lot of fast feedback from a limited number of tests. Julie will look at the fundamentals of classification trees & pairwise and discuss how they can be applied in both traditional and agile environments to give a reduced, but impactful, set of tests. Using examples and through exercises, she will show attendees how to apply these techniques, how they can complement other testing techniques/approaches, and tools to help you apply them in the real world.

NOTE 
Laptops are encouraged, but most exercises can be done without one. There is also an opportunity to apply techniques in the Test Lab.
