Introduction • How effective are branch testing and all-uses data flow testing ? – structural (white-box) testing techniques • path selection techniques • This paper tries to answer this question by reporting an experiment with eight versions of a real-world C program, each containing a naturally occurring (and different) fault. – antenna configuration program developed for the European Space Agency – each version had over 10,000 lines of code 09/ 10/2006 Dr Andy Brooks 3 1. Introduction • In statement testing, a test set is considered adequate if it causes the execution of every statement. • In branch testing (decision coverage), a test set is considered adequate if it causes every edge in the control flow graph to be executed. 09/ 10/2006 Dr Andy Brooks 4 1. Introduction • In all-uses data flow testing, each test requirement is: – “a definition-use association (dua) i.e., a triple (d,u,v), where v is a variable, d is a program point where v is defined, and u is a program point where v is used” – “to cover such a requirement a test case must execute a path that goes from
