【Abstract】 To solve the key problem of how to calculate the effective subset of the control flow paths of the tested program, this paper proposes an algorithm for working out the subset of the whole control flow paths of the program with the help of the LCC compiler in software coverage testing.The control flow paths in the subset are based on the strategy that the loop statements in the program execute less than twice.Adjoining matrix is introduced by the algorithm to work out the subset of the control flow paths with the help of customized stack structure.The correctness of the algorithm is verified on a sample program, which indicates that the subset of the whole control flow paths of the tested program can be calculated efficiently and accurately with this method.更多还原
