The Test Sequences Generation Method Based On UML Collaboration Figure

Computer industry development impells informationization to depth development, with the help of software service industry plan in the "Eleventh Five-Year Plan" software productions will be more widely used in social economic life and will make a deeply influence for more and more people. The quality of the software productions will also become the common focus. However, a lot of programming language, the difference of operating systems and hardware platforms, unceasingly expands of software productions these all make the quality guarantee for the software become a very hard work. Software testing as a key step in software quality assurance can determine success or failure of software products.This paper, taking this as a background, based on UML with the new features of object-oriented program, looking for a scientific generation method to get the test sequences.UML collaboration diagram describe the structure relation and interactive behavior of objects which work together in system, this paper proposes a method to generate integration testing sequence which based on UML collaboration diagram, through analysing the different types of information flow processing method, summed up a series of path covered criteria, and make the polymorphism expansion for the limitations of the test sequences generation algorithm - IRCFG algorithm, Using the improved algorithm to describe the collaboration of objects in the graph generate the test sequence, finally design the integration test sequences generation tool and do some analyzing about the testing sequences which producted by the advanced IRCFG algorithm.This study is a deep practice process of automatic software test, in this study we make a beneficial attempt to improve the software testing efficiency and guarantee the software quality.
