A Tool for Test Case Impact Analysis of Database Schema Changes Using Use Cases

Test cases are a key factor of software testing, which is an important part of software engineering. The value of test cases is related to attribute in database schema. Database schema is a significant component of software, and is increasingly complex. If database schema is changed, it has an effect on test cases. This is hard to identify impact on test cases from database schema changes. This cause brings various problems such as wasted time, cost, and effort to find impacted test cases. Moreover, it needs to redesign for the generation of new test cases. In this paper, we present a tool for supporting our approach to analyze impact of test cases when database schema is changed, besides this tool is based on black-box testing by using use case description, and the tool could generate new test cases to replace the unusable test cases.
