Embodiment Construction

[0053] The present invention will be further described below in conjunction with the accompanying drawings.

[0054] like figure 2 As shown, this tool is an automated testing tool developed based on matlab, matlab is the abbreviation of matrixlaboratory, matlab is mainly used to process entire matrices and arrays, while most other programming languages ​​process values ​​one by one, matrix refers to the linear algebra that is usually used for The two-dimensional array of operations, matlab is a commercial mathematical software produced by mathworks company in the United States. It is used for algorithm development, data visualization, data analysis and numerical computing. Advanced technical computing language and interactive environment, mainly including matlab and Simulink. Matlabu has a rich algorithm toolbox, so it is suitable for engineering calculation, control design, signal processing and communication, graphics processing, signal detection, financial modeling design ...

Abstract

The invention relates to a Simulink model-oriented automatic test tool and method, and the tool comprises a first setting module which is used for setting the comparison precision of a simulation step length and a test result; the third selection module is used for selecting an MIL simulation mode or an SIL simulation mode; the fourth selection module is used for selecting to execute a single test case or multiple test cases; the calculation module is used for calculating the coverage degree of the test; the second setting module is used for setting only comparison of expected time point data or comparison of each simulation step length; the automatic testing module is used for executing automatic testing on the to-be-tested Simulink model based on the test case; the generation module is used for generating a test result based on the current test case; according to the method, the to-be-tested model and the test case can be rapidly loaded by a tester, then one-key automatic testing is completed, the tool is provided with personalized configuration, a user can select required configuration on a front-end interface according to own needs, then personalized testing is carried out, and the application range is wide.

Description

technical field [0001] The invention belongs to the technical field of software testing, and in particular relates to an automatic testing tool and an automatic testing method oriented to a Simulink model. Background technique [0002] Due to the rapid development of new energy vehicle battery management technology, the complexity of software is getting higher and higher. In the process of software development and software iteration, the requirements change frequently, and the workload of software testing is increasing. In automotive electronics and related projects developed based on Simulink models, when the software is modified as the requirements change, the software unit model needs to be tested. Traditional unit testing requires testers to manually perform one by one according to the model and detailed software design documents. Test, the test efficiency is relatively low, the time consuming is long, and there are many repetitive operations. At the same time, there are...
