Design And Implementation Of Automated 5G Basestation Test System

The 5th generation mobile networks has been commercialized in worldwide,comparing with the 4G technology it has been improved with low latency,high speed and large capability.In the development process of base station product,testers play very important role who need to work coordinately with people of design,production and delivery.With the acceleration of commercial use,base station research and development cycle is shortened,and the test time is compressed accordingly.As a tool to improve efficiency,the automated test system takes on an increasing proportion of tasks in the test work.This topic carries out research on the development mode of automatic test system,and selects the keyword driven test Framework based on Robot Framework as the platform to design and realize the automatic 5G base station integrated test system.The main research work of this paper is as follows:1)This paper studies and analyzes the classification and design ideas of the automated test framework,combines the base station product test requirements,selected the keyword-driven test framework to design the automated test system,providing theoretical basis for the design and implementation.2)Analyze and expound the theory of continuous integration,combines automatic test workflow,selects the Robot Framework,a keyword driven robot Framework with some data-driven characteristics,and introduce the language architecture and usage method.3)Introduce the base station hardware and software environment,analyzes the test scenario,and present the detailed test case description and relevant requirements of the test system.4)Design and implement the interface function of all subsystems,adapt different connection methods to implement the base station control interface of BTSSM,InfoModel,Syslog and related test environment instruments.Encapsulate the control operation as a function named after the keyword and mplement control flow according to test cases.Extend the stress test scenario,optimize automatic exception handling and automatic test task trigger.Finally,the test system has been put into the actual test work,realized complete requirements coverage,undertaked the main part of continuous integration test work,executed a lot of test work instead of manual work,and met the design expectations,with the advantages of easy deployment,easy operation,easy maintenance,etc.
