ABSTRACT
When it was first introduced, the All Pairs testing possibility was extremely popular. According to James Bach, more than 40 journal articles and conference papers have been written about the technique (Bach and Schroeder, 2003). It continues to be discussed in recent books on software testing, it is in the ISTQB Advanced Level syllabus, and the practitioner conferences continue to offer tutorials on All Pairs testing. It is tempting to say that more has been written about All Pairs testing than is known. In this chapter, as the title implies, we take a closer look at the All Pairs testing technique, answering these questions:
■ What is the All Pairs technique?
■ Why is it so popular?
■ When does it work well?
■ When is it not appropriate?
