Problems solved by technology

[0003] Embedded software is closely integrated with hardware when implementing design functions. When testing, testers are limited by hardware interfaces, and often cannot fully inject fault data according to the failure mode of the design, especially for some types of closed-loop calculations. type software, it is more difficult to construct relevant fault data

Abstract

The invention discloses an embedded software fault injection method and device, and relates to the field of embedded software testing.The method comprises the steps that an embedded software digital operation platform is built, and a data interface suite is built; creating a corresponding relationship between a communication protocol of an interface and a physical quantity in the data interface suite, and decomposing data in the communication protocol to the corresponding physical quantity; a data DLL and a control DLL are created, and the data DLL is used for storing normal external excitation of the embedded software and outputting physical quantity associated to the data interface suite and embedded software of a closed-loop solution type; and controlling the DLL to obtain normal external excitation or standard resolving data from the data interface suite, and superposing error data or replacing the normal external excitation or standard resolving data with error data based on test requirements to realize test fault injection. According to the method, the effectiveness of embedded software testing work can be guaranteed.

Description

technical field [0001] The invention relates to the field of embedded software testing, in particular to an embedded software fault injection method and device. Background technique [0002] Effective software testing is an important means to improve software quality. As a method to accelerate system failure, fault injection technology can accurately obtain parameters such as system test coverage and error latency, and has been widely used in software testing. . By monitoring and analyzing the process of accelerating the failure and failure of the system after injecting the fault, the period for obtaining the test results of the reliability and fault-tolerant characteristics of the software under test can be greatly shortened. Therefore, fault injection technology plays an important role in improving software quality, reducing software harm, and improving software development process. [0003] Because embedded software is closely integrated with hardware when implementing ...
