Research And Application Of Automatic Test Case Generation Method For Data Oriented Standard

The compliance test of the software standard is the degree of conformity between the testing software and the standard.As the industry standard is changing constantly,the work of software standard compliance testing is becoming more and more important.The design and generation of test cases is the core part of the software standard conformity test.In order to avoid the formation of the traditional manual method of low coverage,low test efficiency,large amount of redundant test cases,this test case automatic generation method for data standards,In this paper,the method of automatic generation of test cases for data class standard is put forward,and further analysis and research are carried out,which reduces the influence of manual intervention,enhances the test efficiency and realizes the aim of improving the quality of test cases.This paper takes data class standard as the breakthrough point,explores the data class standard structure composition and commonality,test case automatic generation technology,test case validity evaluation method,and builds standard compliance test platform based on research results.First of all,the paper analyzes the standard of data in automobile,textile,press and publication industry,and studies the common structure so that machine language can deal with the standard.Then,for the standard generic structure of data class,a test case generation method is proposed,based on the priority ranking technique,the APPD weight allocation technique is proposed as the evaluation method of test case effectiveness,and the optimal test case set is constructed based on the evaluation of validity.Finally,the test Case Library Management system is established and the research results are applied in the system.In this paper,boundary value method is applied to deal with test case generation of non associated data elements in data class standard.The causality diagram method and decision table method are combined to effectively cover test case generation of related data elements in data class standard.By assigning weights to each test case and adjusting weights dynamically according to the test results,a test suite with higher coverage and better detection effect is constructed.The test case database management system is designed and implemented,which is applied to the CNONIX standard compliance test of the press and publication industry,which reduces the labor cost and improves the detection efficiency.
