An Improved Test Case Generation Method based on Test Requirements for Testing Software Component

With the rapid development of computer science and technology, the scale of software is becoming much bigger, and the advantages of components also makes it deeply used in component-based software engineering. However, once some security risks appear in the components, then, the whole software system would suffer irreversible problems or even fatal collapse. In recent years, various testing methods have been proposed to ensure the component security, but these traditional component testing methods did not consider whether the process of software testing satisfies the testing requirements, which causes the generated test cases cannot effectively detect potential faults in components. To solve this problem, this paper proposes an improved test case generation method based on testing requirements, namely TGTR, to generate effectively test cases for better detecting the software faults. We first construct test requirement meta model through selecting some features of the system under test; And then, we convert the state diagram model of the system under test to marker migration system based on the designed migration path generation algorithm; Finally, we generate the improved test cases through reachable path. Experimental results on three components show that the method optimizes the migration path compared to traditional test methods, resulting in fewer test cases while achieving similar detection efficiencies and taking less time.
