The research and implementation of automatic unit test recording framework

There is no information exchange between system test and unit test in existing automated testing techniques, unit tests usually ignore the requirements of users, but the system test has shortcomings like inefficient and hard to explore the error. Base on this problems the paper designs an automated testing framework. The framework record unit test from system test. In the process of the research and implementation of the framework, the issue compares a variety of automatic test data generation methods. and makes a improvement of orthogonal design method. we discuss the realization of the unit test recording, and apply the data flow analysis and symbolic analysis techniques to the process of unit test recording.
