Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] The dirty data propagation path discovery method based on the complex network of the present invention mainly includes three parts: a path analyzer, a predicate inserter, and a test data generator. First, the path analyzer analyzes the code of the input source program to obtain the path table of the source code program. At the same time, the predicate inserter performs predicate instrumentation on the input source code, and the code and path list after instrumentation are output to the test data automatic generator at the same time. The test data generator mainly uses the hierarchical genetic algorithm and Huffman coding. For the fitness function, first, the hierarchical genetic algorithm stratifies the initial population, and performs genetic operations such as mutation, crossover, and selection within and between layers. The construction of the fitn...

Abstract

The invention provides a test case generation method based on a hierarchic genetic algorithm. The method can be used for effectively preventing and controlling inbreeding, so that the problems of premature convergence and local convergence are effectively solved. The method includes the steps that a program source code is inputted into a path analyzer, and the path analyzer carries out path analysis on the inputted program source code, then obtains a corresponding path list and outputs the path list to a test data generator; a predicate instrumenter carries out predicate instrumentation on the inputted source code and outputs the instrumented code to the test data generator; the test data generator firstly carries out hierarchy on an initial population through the hierarchic genetic algorithm, compares passing paths of individuals in hierarchies with objective paths of the individuals in the hierarchies through the utilization of the instrumented source code to obtain the matching values between the passing paths and the objective paths, and finally the test data generator gives test cases to the paths.

Description

technical field [0001] The invention relates to a method for generating test cases based on a layered genetic algorithm, belonging to the technical field of software testing. Background technique [0002] With the rapid development of computer technology and science, as the soul of computer, software plays a pivotal role, and the failure of software may cause huge economic losses and even endanger life safety. People are more and more aware of the importance of software testing, and the proportion of software testing phase in the entire software development cycle is increasing day by day. Existing software testing technologies are generally divided into static testing and dynamic testing from the perspective of whether the software under test needs to be executed. Static testing is the process of finding possible bugs in the program code or evaluating the program code without executing the program code. Dynamic testing checks the program's dynamic behavior and running resu...
