The Design And Implementation Of Edge Test System Of IoT Testing Cloud Platform

With the continuous expansion of the scale of the Internet of Things,more and more communication devices are involved in the Internet of Things,and the requirements for communication stability of communication devices are also higher and higher,which leads to increasing requirements for equipment testing.To solve this problem,a test cloud platform has emerged.The test cloud platform is based on related technologies of cloud computing,and can dynamically assign test tasks to the test system located at the edge of the cloud according to requirements,so as to improve the test efficiency.Edge of the test system is the bottom part of the cloud platform interoperability test,was a key part of the complete test task,its test efficiency will inevitably affect the test efficiency of the entire cloud platforms,but too much manual intervention is the current test system,test automation degree is low and high coupling system function,system function is not convenient to extend the pain points,etc.Based on the above background,this paper studies the edge test system in the test cloud of the Internet of Things.The main research contents of this paper are as follows:1)Based on the characteristics of the device interop test environment,the architecture of the test system is designed as an agent-based distributed system architecture,which reduces the coupling degree between system functions,facilitates the function expansion of the system,realizes the system test automation and improves the test efficiency of the test system.2)Based on the message-oriented middleware technology,the message model of communication between the agents within the test system is designed to shield the differences between different platforms and complete the system's adaptation to multiple platforms.3)Design the test case generation method based on process decomposition,change the original test case customization mode,and realize the test case can be edited autonomously.4)Design and implement the test system.The test system is divided into three modules from the function,and for the function of the three modules for demand analysis,and then based on the demand analysis of the module for the outline design and detailed design,and then to achieve the function of each module,finally complete the system function test,verify the design of the test system function in line with expectations.
