Embodiment Construction

[0015] This patent uses data perturbation to implement the calculation accuracy test of the underlying software and hardware of intelligent transportation, mainly using the precision perturbation method library and the construction technology of precision risk indicators.

[0016] (1) Design of accuracy perturbation method library

[0017] In the present invention, we design the precision perturbation method library D from five angles of precision outliers, operation rules, scaling, precision truncation, and data disturbance. Accuracy anomaly disturbance introduces accuracy-related abnormal data types and abnormal ranges and other related data content. The operation law adds interference to the data accuracy operation process and operation method. Scale scaling is conditionally enlarged and reduced for the data scale in the field of intelligent transportation. Divided into various forms of precision interference such as partial and overall scaling, precision truncation cuts hi...

Abstract

According to the invention, the metamorphic test technology is adopted to test the correctness of the intelligent traffic model, a metamorphic relationship applied to the intelligent traffic model isdesigned, the correctness of program functions is judged from multiple aspects, and an original case and a derivative case generated based on the metamorphic relationship are used for testing the intelligent traffic model, and checking whether the outputs of the original and derivative cases meet the corresponding metamorphic relationship or not to obtain a test result. According to the method, the correctness of the intelligent traffic model can be reasonably measured and evaluated by adopting a new software testing method.

Description

technical field [0001] The invention belongs to the field of software and hardware testing, and in particular relates to the testing of the operation accuracy of the underlying software and hardware of intelligent transportation. By designing a series of perturbation method libraries for processing, selecting a perturbation method and setting perturbation parameters for specific software and hardware scenarios, an accuracy test sample set is generated, and a conditional specification is used to generate an accuracy evaluation threshold for accuracy analysis. Background technique [0002] Perturbation-based data-driven testing is an important method to ensure the reliability of scientific computing software. There is currently a detection method for numerical and code stability, which consists of two perturbation strategies: numerical perturbation and expression perturbation. Among them, the numerical perturbation is mainly to replace the non-precision key byte or intermedia...
