Design Of Automatic Test System Based On WCDMA Testing Items

With the complication and diversification of the measured object and the electronic equipment,and complicated system testing,it is required that the test software can control a plurality of communication equipments,instruments and equipments in the testing process,and more tedious test operations need to be performed.The demand for test systems in modern society is also increasing,which means that test software needs to have higher validity and reliability.Therefore,traditional test system software can not meet modern test requirements.Therefore,it is particularly important to develop efficient automated test system software.This article is based on the "standard for WCDMA measurement in the 3GPP protocol".First,we introduce the background of the research and the development status of the test system.Then,based on the test requirements of the system,the indepth study of the test tasks to be completed by the software of the test system is carried out.Based on this,the design of the software is proposed.With the software design as the core,the design of each functional module in the software is introduced in detail.achieve.The main work is as follows.1.From the software requirements,elaborate the software design ideas and module division.Based on program calls and module design ideas,the whole system software is designed based on the object-oriented idea,and the overall framework design of the software is given on this basis.2.According to the composition of the measured object,summarize the functional operations that must be implemented in the items such as measurement items,instruments and equipment,and provide the corresponding interface.Define a series of functions in the interface.The class that inherits the interface must implement these functions.3.Summarize the commonality of different test cases,and give some abstract classes of the corresponding class.According to the workflow of the software,the main test parameters of the system are summarized in detail,and the specific test flow is given.4.Detailed design of software function modules.Designing the information interaction between the user interface and the test class enables the user to know the specific conditions of the test;designing message passing and event-driven mechanisms to construct work coordination and data interaction modes among the various modules.This article uses the C# programming language to complete the design of the system software under the Visual studio 2010 development environment.The experimental results prove that the software can realize the automatic testing of the measured object and save the test result.The automation degree is high and it has certain engineering significance.
