The Research And Implementation Of Automated Test Case Construction Techniques For Lottery Game Terminal System

With the rapid development of the IT industry,the rapid development of hardware in quality and quantity has left a deep impression on people.Relatively speaking,software also developed rapidly in terms of quantity,but the quality of software has always been a headache.With the expansion of software scale,the assurance of quality has become an extremely difficult task.Therefore,effective testing of software becomes the most important and most effective method for ensuring software quality.Software testing is an important means of ensuring software quality and is an important part of the software development process.How software testing work is done directly determines the quality of software products.A large number of statistical data indicate that the cost and workload invested in the software testing phase often account for 40% to 50% or more of the total cost of software development and total workload.With the expansion of the scope of software applications,the improvement of software complexity,and the continuous development of software design technologies,the scale of software development is getting larger and larger,and the problems of processing are becoming more and more complicated..With the ever-increasing scale of issuance of welfare lottery,problems in the development and testing of lottery game terminal systems have gradually emerged and magnified.A single lottery terminal system has a large number of games,complex systems,and high reliability and security requirements.Its structure and functions are very complex.If test cases rely too much on manual input,the efficiency is not only very low,but the use cases are not standardized.Norms will make the test quality can not be guaranteed.In this case,it is very important to introduce the automated test generation technology into the lottery game terminal system.This subject will use AJOffutt's test case generation algorithm based on state description.According to the characteristics of the domestic lottery terminal game system,it improves and improves it,and proposes an automatic generation method for test cases of lottery game terminal system based on UML state diagram.The three-layer design method from UML to XML Schema models the lottery game terminal system.Finally,the automatic test case generation tool is designed and implemented.This use case automatic generation algorithm and tool for the lottery game terminal system will effectively improve the efficiency and reliability of the game testing in the domestic lottery industry,and is of great significance to the future development of the national lottery business.e.
