导航地球站软件接口测试用例设计

Test case design for software interface of GNSS Earth station

以导航地球站软件测试为背景,介绍了导航地球站工作单元结构及软件接口情况,概括了因果分析、等价类划分和边界值分析等3种测试用例设计方法。分析了接口报文包头信息和数据体中控制类信息、状态上报类信息的特点,阐述了各传输模式下测试用例设计方式。最后以某卫星导航地球站的部分接口测试为实例对测试用例设计方法进行了验证。

With a view to the software test, the structure and interface of GNSS earth station are introduced and three kinds of test case design methods including causal analysis, equivalence partition and boundary analysis are generalized. The characteristics of interface message including head information, control information and statement reports are analyzed, and the test case design methods for various transmission modes are expounded. The test case design methods have been verified through the test for a part of the interfaces of a navigation station.
