LXI数据采集器软件测试方法

Software testing methods of data collector based on LXI

LXI数据采集器目前正处于蓬勃发展的阶段,符合测试系统发展的趋势,为了保障LXI数据采集器的正常使用、判断LXI数据采集器与LXI协议是否一致并测试系统的其他性能指标是否满足技术要求,本文提出了一种黑盒测试方法,开发一套软件系统,通过截取并分析局域网中与LXI采集器有关的数据包,对LXI采集器进行网络发现的测试、数据通信及其可靠性的测试、同步测试及触发功能测试等。实践证明,该测试系统能够对LXI数据采集器进行有效测试,可靠性高、可维护性高、便于升级、通用性强。

LXI data collector is now in the stage of booming and conforms to the trend of the development of the test system,in order to ensure the normal use of LXI data collector,judge if LXI data collector is in accordance with LXI protocol and the other performance index meets the technical requirements,this paper puts forward a method of black box testing,developed a set of software system,by capturing and analyzing data packets associated with LXI collector in the LAN,to test the network discovery of LXI collector,data communication and the reliability,synchronization and trigger function,etc.The practice has proved that the test system can effectively test the LXI data collector,has high reliability,high maintainability,strong commonality and easy to upgrade.
