Rapid and parallel communication protocol test method applicable to large system

Abstract

The invention relates to a rapid and parallel communication protocol test method applicable to a large system. The rapid and parallel communication protocol test method applicable to the large systemcomprises the steps of: dividing the large system into multiple sub-systems and devices, and setting a single sub-system or single device as a basic communication unit; specifying a communication protocol used by each basic communication unit, wherein each command of each basic communication unit corresponds to a sub-file; traversing a file, reading the name of the basic communication unit, and constructing a link graph of the large system according to the device linked to the basic communication unit in the specification protocol; comparing a protocol realized by a program with a protocol described by a document, and comparing a communication protocol specified according to a program code and a communication protocol specified according to document description; and, on the basis of a document description protocol, performing communication protocol consistency comparison on a protocol linked to the basic communication unit, if there is any inconsistency, prompting, and displaying auxiliary information on the link graph of the system.

Description

technical field [0001] The invention relates to a communication protocol testing method, which is a fast parallel testing method for communication protocols suitable for large systems. Background technique [0002] There are multiple subsystems and equipment in a complex large system, and the correct information exchange is performed between each subsystem and equipment through the interface communication protocol. If there is a deviation in the understanding and implementation of the same protocol between the subsystems and equipment, Or using different versions of the communication protocol will cause communication errors and the system cannot work normally. In the process of system testing, it often happens that each subsystem or a single device passes the test, but in the working environment of a large system, the system cannot work normally after the software is connected. [0003] After analysis, most of these problems are caused by uncoordinated software interfaces. ...

AI Technical Summary

Problems solved by technology

At present, the review of communication protocols between multiple subsystems in the system and between equipment and equipment is mostly carried out by manual repeated checks. The heavy workload and fatigue of the personnel will easily lead to incomplete testing, especially when some software interfaces in large systems are changed. After that, the impact domain analysis of the whole system may not be sufficient

[0004] If the system involves a total of N devices, assuming that each device communicates with each other, the interface review during system testing needs to review 2*(N-1)! Whether the interface link is correct or not, each tester must communicate with N-1 testers. If the change of testers is considered, it will cause a huge workload, low efficiency, and inevitable duplication of work
