Path coverage testing is almost impossible to achieve because of the large number of paths. The function calling path coverage analysis method can guaranty adequate test coverage rate effectively on the precondition of unit testing completion. Based on function calling relations, the methods of dynamic generation function calling path is proposed. For cycle and recursive calling, design instrumentation rules and probe function, complete source code instrumentation, ensure the stub point flow can trace to the function calling relations. The function calling path generation algorithms were designed to split the stub point flow to the dynamic function calling path. Experimental results show that the dynamic function calling path generation method based instrumentation can extract the function calling paths which are executed by test cases and gain the coverage of information automatically.

Automatic test case generation has been a hotspot and a difficult problem in the software testing, Accurately and efficiently generate test cases can improve the efficiency of software testing. Java programs have many characteristics such as encapsulation, inheritance, polymorphism and so on, it is convenient for software design and development, but to bring automated testing some difficulties. This article on the Java program of automatic test case generation method is studied and presents a framework for automatic generation of test cases. With this framework, test case suite will be generated quickly and accurately. Experimental results show that automatic Java test case generation framework can quickly and accurately generate test cases , reduce labor costs and improve efficiency.

There are some issues in the manual test ofUOF/OOXML Translator, such as the low efficiency, difficult measurement of test case coverage and project delay. This paper brings about the automated testing process model based on the manualVmodel ofUOF/OOXML Translator, and proposes the implementation scheme of automated testing process through analyzing test case automatic generation, test case management, automatic contrast of function points and defects management. The experiments have shown that this model can effectively manage test cases and defects, and even replace manual testing partly. Besides, this model can improve testing efficiency and reduce test workload, preventing the defects occurring in the late project stage.

The existence of the polymorphism brings many changes on the executable paths of the object-oriented program, which makes it difficult to test the internal communication of the system and the interaction between the objects. This paper analyzes the structure feature of the Java program and builds an inheritance tree using the technique of reflection in Java, which guarantees the accuracy of the analysis data. This paper proposes an algorithm to determine the uniqueness based on the full analysis of the Java polymorphic calling states and the Liskov substitution principle. And the algorithm uses the asynchronous mode of high concurrency to increase the efficiency. The result shows the algorithm can determine the uniqueness of polymorphism efficiently and accurately. It can play an important role in the Java program comprehension and the system maintenance.
