Function Test Design And Implementation For The Civil Aviation Atmosphere Information Transmission System

With the development of the times,the size of software is increasing,so is the softwarecomplexity,the quality of software has been more and more attention.The level of software testingtechnology has improved rapidly since then.Software testing is a very important part of softwareengineering,also is part of the software development process, which has a huge impact on thequality of software products and the length of the software development cycle.Functional testing isthe third stage of software testing,and it plays a vital role in software quality assurance andrelease effect,while different software systems have different features,Doing the functional testsfor the characteristics of the current software systems is the best way to ensure the system hascompleted the user requested features,and find out the flaws as much as possible in the system,effectively improve software quality eventually.In this paper,the civil aviation atmosphere information processing and transmission prototypesystem is analyzed.Functional testing and regression testing for problems found for the systemwill be finished.The test based on the full analysis of the civil aviation atmosphere informationtransmission system requirements specification,combined with the structural characteristics ofaviation atmosphere information transmission system.The civil aviation atmosphere informationtransmission system was divided into several functional modules, and each is selected differenttest case design methodsAccording to the functional requirements and development result of themodule,then design reasonable and rigorous test cases while reducing tester’s workload and workpressure, found problems in the system by executing these test cases.After developer modify the code,design regression test cases and do regression testing for the problems found infunctionaltesting stage,to confirm that the problems found have been modified and produce no problem.
