摘　　要：在传统的交换设备软件测试中,由于机框式设备的存在,相关板卡热拔插的可靠性和稳定性测试是整个系统测试中的一个重要测试环节,而如何快速有效地测试设备上的各种板卡的插入、拔出成为了当前测试的难点和挑战。因此,提出一种基于软件模拟的板卡插拔方法,支持用户终端下发命令模拟板卡的模拟拔出和模拟插回,用于验证硬件拔插后的软件功能是否正常;通过脚本控制可以模拟插拔支持反复执行,用于验证硬件在一定数量级次数的拔插后软件功能是否正常;模拟插拔支持短时间的快速执行与恢复,用于提前暴露软件功能上的时序问题。结果表明,该方法可以提升测试效率,节约人工和物料成本,并提高相关测试环节的覆盖度和测试精度。In the traditional software testing in switch,due to the existence of rack type equipment,the reliability and stability testing of related board hot plugging also belong to an important test in the whole system testing,how to effectively test the insertion and extraction of various boards and cards on the equipment has also become a challenge in the current test.This paper proposes a method of board card plugging based on software simulation,which supports the user terminal to issue commands to simulate the simulated pulling out and plugging back of the board card,which is used to verify whether the software function is normal after the hardware is plugged in,and can simulate the plugging and plugging support repeated execution through script control,which is used to verify whether the software function is normal after the hardware is plugged in a certain order of magnitude.Analog plug-in supports fast execution and recovery in a short time,which is used to expose the timing problems of software functions in advance.The results show that this method can improve testing efficiency,save labor and material costs,and improve the coverage and testing accuracy of relevant testing links.
