Boundary value testing method in industrial software site test based on user historical data

Abstract

The invention discloses a boundary value testing method in an industrial software site test based on user historical data, and belongs to the field of the software testing. A severe loss can be brought to the user site production by the site test of the industrial software, and a production accident is easily caused by just legal data and just illegal data near a boundary value. Recent illegal data and recent legal data near the boundary value are found out through the excavation to the historical data of the user production site, and production state information caused by the data is analyzedaccording to the corresponding historical process data, the related data is evaluated whether to be used as the input data of the boundary value testing, and the corresponding treating process data of abandonware in the historical data is used as the comparison evidence output by the tested new software site test. The method is capable of getting the boundary value testing data on the basis of the specific user production historical data processing. The boundary value testing data is closer to the practical situation of a user. The testing efficiency and sufficiency are improved under the precondition of effectively preventing an accident risk.

Description

technical field [0001] The invention belongs to the technical field of industrial software testing, and in particular relates to a boundary value testing method in field testing of industrial software based on user historical data. Background technique [0002] The technology related to industrial software is constantly developing, and the online software of industrial devices is also being updated. Many old process industrial production devices still need to run normally for a long time, and the online software systems of these devices may also need to be updated. However, there are also phenomena where the trial operation of new software systems fails on-site in industrial production facilities. For example, petrochemical production is high-temperature and high-pressure, flammable and explosive, and the risks are too high. When users find bugs in the new software, they immediately stop the trial operation and dare not continue to take risks. In fact, before these failed on...

Problems solved by technology

[0005] The invention provides a boundary value testing method in field testing of industrial software based on user historical data, which is used to solve practical problems in the field implementation process of the existing boundary value testing method, and overcomes various shortcomings of commonly used field passive testing, For example, it is difficult to actively control the test target and process, without designing test cases, the test efficiency is generally low, and the coverage rate is low, which prevents technical problems such as production accidents caused by just legal data and just illegal data near the boundary value in active testing
