The Design And Realization Of Test Data Generation And Management Subsystem Of Supporting Platform Of EJB

The software test cost is a big portion of the total software cost. Improving the efficiency of test and decreasing the cost of cost have special significance for decreasing the cost of software. Test data generation is a process that takes a mass of resources. It is becoming an important problem that how to decrease effort tests have to pay in the test data generating process. Mean while, better organization of test data and efficient reuse of existing test data can also heavily improve the efficiency of software testing.EJB technique is a business component technique which is widely used in recent years. So it is very important to ensure their quality. Software testing is one of the most important techniques used to assure the quality of EJB component at present.In order to carry out test automation about EJB component more effective, we developed an EJB test platform. This thesis is mainly about test data generation and organization subsystems of the test platform. In this thesis, we design a method that uses template to generate mass test datum. There are two kinds of templates: test data template and test sequence template. We propose their definition and provide algorithm to instantiate them. The user just need to write template, then our system will automatically generate test data or test sequences that satisfy the template.In this thesis, we also provide a method to organize test data. In thesis, data associated with testing are well managed. We use XML document to store these data, and operations on them such as create, modify, delete and query. The system implement data reuse with object data as the minimum unit of reuse, and the system also provides analysis for single or more test results, and gives guidelines to testers.
