Abstract

Aimed at a problem that error locating efficiency in software test is low, the invention discloses a software error locating method based on variable slice and association rules. The method comprises: aimed at a Java program statement, performing variable slice, using all variable slice line number information as a transactional database; then using association analysis to obtain an association rule set, according to high-to-low sort order of confidence coefficient and support degree, generating an examination statement priority order; finally, according to a principle that the closer to the top the priority order of the statement is, the more prior the statement is examined, locating the specific position of the error. The method locates software errors combined with the variable slice technology and an association rule algorithm, so that efficiency of software error location is improved, and software test cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of software testing, and specifically relates to the problem of software error location. It provides a software error location method based on variable slices and association rules, which mainly solves the problem of low efficiency in error location, so as to improve error location efficiency and reduce testing cost purposes. Background technique [0002] With the continuous popularization and deepening of software applications in various industries, software quality has gradually become one of the core forces of industry competition. How to ensure software quality has become the focus of developers and testers, and software error location is one of the most expensive and time-consuming activities in the debugging process, and it is also a key task to ensure software quality, improve debugging efficiency, and reduce testing costs . [0003] At present, software error localization has become a research hots...
