Research on Software Automatic Test Method Based on Cause-effect Diagram

This thesis introduces white-box test,black-box test and software test automation technique in the methods of software test.The quality between white-box test and black-box test is analyzed in the test of user access management system.And test cases are designed based on the cause-effect diagram method of black-box test.At the same time,the automatic test script based on shell script language of Linux operation system is practically applied to the user access management system,which indicates a novel way how to carry out automatic test based on the cause-effect diagram.
