Abstract

The invention discloses a multi-path coverage test data coevolution generation method for a message-passing parallel program, and aims to efficiently generate test data covering multiple target pathsfor the message-passing parallel program. The method comprises the following specific steps of (1) constructing corresponding populations for the target paths in each scheduling sequence respectively,wherein individuals in the populations are coded program inputs; (2) designing population performance and individual performance evaluation indexes; (3) solving the populations by using a genetic algorithm, and migrating the individuals to the populations with good performance through individual migration in the process; and (4) stopping evolution of the populations corresponding to the covered target paths according to evolution results of all generations, and stopping an algorithm until the test data covering all the target paths is generated or maximum evolution generations are reached.

Description

technical field [0001] The patent belongs to the field of software testing, and specifically relates to a co-evolutionary generation method for multi-path coverage test data of a message passing parallel program, which can be used in software testing to generate test data covering multiple target paths. Background technique [0002] Software testing is an important part of the software engineering field, and choosing an excellent testing method can effectively guarantee software quality. Among many software testing methods, a commonly used method is to generate high-quality test data and use the test data to execute the program, in this way to find defects or errors in the program running process. However, there are two difficulties in adopting this method: one is that it takes a lot of time to generate effective test data; the other is that the quality of test data is difficult to be guaranteed. If a suitable method can be adopted to generate high-quality test data at a sm...
