Abstract

The invention discloses a method for generating mutation test data based on multi-population co-evolution. The purpose is to gradually reduce the number of variants that are difficult to kill when using multi-population co-evolution genetic algorithm to generate test data according to the information provided by population evolution. Search domains to improve the efficiency of generating mutation test data. First, determine the hard-to-kill variant based on the accessibility difficulty of the mutant statement and the number of input variables involved in the program; then, establish a mathematical model for the generation of mutation test data based on path coverage constraints; finally, for the hard-to-kill variant Based on the information provided by population evolution, the multi-population co-evolutionary genetic algorithm is used to determine the timing and strategy of reducing the search domain, dynamically reduce the search domain, and quickly and accurately generate mutation test data.

Description

technical field [0001] The invention relates to the field of computer software testing, and designs a method for generating mutation test data based on multi-population co-evolution. The difference between this method and the original method is that, for the hard-to-kill variants, when the multi-population co-evolutionary genetic algorithm is used to generate test data, according to the information provided by population evolution, the search domain is gradually reduced to improve the generation of mutant test data. s efficiency. Background technique [0002] Software testing is an important means to ensure software quality. Through testing, not only can detect possible defects in software, but also improve the reliability of software. Mutation testing is a defect-oriented testing technique. Mutation testing is often used to evaluate the quality of test data sets, and is also used to assist in generating test data. [0003] Difficult-to-kill variants are those that cannot...
