Functional Test Generation for Extreme Programming

Test generation and the engineering, including maintenance, of the set of test cases are a key part of the Extreme Programming approach. Since so much depends on the viability of these test sets it is therefore important that methods for constructing them make use of the best available techniques. Total testing provides a mechanism whereby test sets are created which can detect ALL possible faults in an implementation, provided that a number of key conditions are satisfied. This paper describes how total testing can be used in Extreme Programming and illustrates the concepts with a simple case study. The methods proposed here are being used in a number of industrial projects and some interim conclusions from these are presented.
