Abstract :
Data-flow testing is a well-known technique, and it has proved to be better than the commercially-used branch testing. The problem with data-flow testing is that, apart from scalar variables, only approximate information is available. This paper presents an algorithm that precisely determines the definition-use pairs for arrays within a large domain. There are numerous methods addressing the array data-flow problem; however, these methods are only used in the optimization or parallelization of programs. Data-flow testing, however, requires at least one real solution of the problem for which the necessary program path is executed. Contrary to former precise methods, we avoid negation in formulae, which seems to be the biggest problem in all previous methods
