Automated Generator for Complex and Realistic Test Data

Some type of tests especially functional tests and stress test requires a large amount of realistic test data. We are proposing a tool that uses random number generators in order to create such data. The tool is designed to be able to set simple attributes of any Java object and in many cases also to create complex structures when objects are connected via references. Random values are created according to the rules that are added to the class definition in form of annotation to each attribute. Using this tool simplifies creating of tests, as the tester do not need a detailed knowledge of data structure. The specification of expected values is delegated to the designer of data model and becomes the part of the model. Furthermore, as the data objects are created at runtime, using reflection, the tests do not have to be changed when data carrying objects are modified.
