Research and Application of Data-driven Testing Based on LoadRunner and Design Method of Orthogonal Test

In order to realize the automation and get twice the result with half the effort in functional testing of software,mathematic definitions of test logic,test data(set) and test case(set) are introduced,and the relationships among these definitions are also given.And then an automatic testing technology of software is presented,which is a data-driven testing technology based on LoadRunner and design method of orthogonal test.Firstly,a test logic is generated by means of software testing tool LoadRunner.Secondly,comparatively fewer logic,high-quality and typical test data are generated based on the design method of orthogonal test.Finally,by means of software testing tool LoadRunner a test case set of this test logic is executed automatically,and correspondingly its test results are analyzed.At the same time,an application example of the automatic test technology of software is given.Experimental results show that this technology can reduce the number of test cases and improve test efficiency.
