A Fast Parallel Testing Method for Communication Protocols Suitable for Large System

Abstract

The present invention relates to a communication protocol rapid parallel testing method applicable to large systems, comprising: dividing a large system into multiple subsystems and equipment, setting a single subsystem or a single equipment as a basic communication unit; The communication protocol used by the communication unit is standardized; each command of each basic communication unit corresponds to a sub-file; traverse the file, read the name of the basic communication unit, and according to the equipment linked by the basic communication unit in the standardized protocol , build a link diagram of the large system; compare the protocol implemented by the program with the protocol described in the document, and compare the standardized communication protocol implemented based on the program code with the standardized communication protocol based on the document description; take the document description protocol as the The basis is to compare the consistency of the communication protocol with the protocol linked with the basic communication unit. If there is any inconsistency, it will be prompted, and the auxiliary information will be displayed on the link diagram 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
