Tutorial Overview

This one-day workshop introduces participants to an essential “grab-bag” of advanced test case design techniques. 

The course commences with a brief discussion of black-box and glass-box test models followed by a discussion of practical test coverage criteria for both models.

The course then moves on to an in-depth discussion of various black-box testing techniques.  This is followed by a demonstration of how the techniques can be applied to both the conventional and “model-based” approaches to testing.

The second-half of the course covers glass-box testing techniques and shows how these may be applied to both conventional testing and the static analysis of program code.

The course concludes with a brief discussion of how the techniques learnt during the course can be used with automated test tools.
