Protocol test device and method for realizing protocol test

Abstract

Core of the invention is that based on condition of protocol test, levels of units not related to protocol, and units related to protocol are divided. The units not related to protocol executes operation processes, which are not related to specific content of protocol and are suitable to test any protocol. The units related to protocol is in charge of operation processes for specific testing protocol. Further, the invention marks off corresponding general procedure module for protocol test from units related to protocol as a common part in use for testing each protocol repeatedly. Advantages are: ensuring reusability of protocol related layer furthest, avoiding rehandling development procedure for testing set. The invention possesses high generality, reusability and extensibility.

Description

technical field [0001] The invention relates to the technical field of network communication testing, in particular to a device for layered protocol testing and a method for implementing the protocol testing. Background technique [0002] Network protocol is a very important concept in the field of modern communication, and it is a set of specifications for network communication. The correctness of the protocol implementation is the basic guarantee for the normal operation of the communication network. The protocol test is an important means to ensure the correctness of the protocol and the interoperability of network products. Any protocol product should pass the corresponding protocol test before being put into use. [0003] The protocol test can be divided into two stages, the first stage is the construction of the test set, and the second stage is the execution of the test set. The test set is usually an abstract operation process described by a formal language, so it...

AI Technical Summary

Problems solved by technology

[0017] 1. The development cost of constructing the test execution environment is very high. No matter whether the translation method or the interpretation execution method is adopted, complete support for TTCN syntax and semantics is required;

[0018] 2. The code execution efficiency is not high;

[0019] 3. There are still difficulties in supporting some testing methods, such as distributed testing, etc.

[0025] However, the test method based on scripting language also has disadvantages such as poor versatility and poor reusability of the test framework structure.

Because the entire execution environment is designed for a certain protocol, when the test of other protocols is to be completed, all content needs to be restructured; usually a test command completes a specific protocol function, although different protocols are in There are common parts in these functions, but due to the specificity of test commands and their tightly coupled implementation, it is difficult to reuse the functions of the common parts, so a lot of repetitive work needs to be done when developing test sets for multiple protocols, so Reduced efficiency in developing protocol testing tools
