Embodiment Construction

[0022] In order to facilitate those of ordinary skill in the art to understand and implement the method proposed by the present invention, the present invention will be further described in detail and in-depth through specific embodiments below.

[0023] Mounting point management software (SMS) is a typical airborne embedded software, and its input and output are realized through serial port communication. Therefore, specific embodiments of the present invention will be described for the test of SMS software.

[0024] Such as figure 1 As shown, the system structure adopted for testing SMS software using the defect injection and control method of the present invention, a defect management module 3 and a communication scheduling module 4 are set in the target machine 2 where the SMS software 5 to be tested is located. The defect management module 3 manages the defect configuration, and schedules the serial port and network information when the software under test is running. Th...

Abstract

The invention provides a reliability test defect injection and control method of embedded software, which comprises the following steps of: arranging a defect management module and a communication scheduling module in a target machine of the tested embedded software, enabling a researcher to carry out defect injection and control on the tested embedded software through a test platform, carrying out defect tracking control and software function execution on a synchronous basis in parallel, adopting different channels for the defect tracking control and the software function execution and generating no conflict among data. The reliability test defect injection and control method of the embedded software has the beneficial effects that software defects can be user-defined according to the actual demands of subject research and test; the software defects of the tested embedded software can be set according to the demands of the researcher; and after the software failure occurs, defect numbers which cause the failure are reported, so that a plenty of time required by debugging and troubleshooting is saved, thereby the efficiency of software failure subject research can be improved, the controllability of the software failure is improved, and the more targeted research on the software reliability is realized.

Description

technical field [0001] The invention relates to the field of software testing, in particular to a technology for conducting software reliability testing research on embedded software. Background technique [0002] With the increasingly widespread use of computers, people have higher and higher requirements for software quality. As the most important content of software quality—software reliability, it is naturally valued by people. How to test software reliability is one of the basic problems in software reliability engineering. At present, the main method of quantitatively testing software reliability is to model the software reliability (failure) data collected during the testing process in the software testing stage to estimate the actual level of software reliability, so as to judge when the software is The test can be stopped and delivered to the user for acceptance. [0003] Software reliability assessment is mainly based on software reliability model. The software ...
