Abstract

The invention belongs to embedded type software test methods and particularly relates to a method for building an AD / DA interface fault model on the basis of an NI platform. The method comprises a first step of setting different fault injection data parameters and fault injection files according to the cross-linking environment of tested software and the fault injection requirements; a second step of jointly configuring the fault injection data parameters and the fault injection files to a fault injection tool; and a third step of performing connection to carry out a test according to the cross-linking environment of the tested software and the AD / DA fault injection tool cross-linking requirements. The method has the advantages that AD / DA faults can be simulated so as to improve test sufficiency, and the quality standard of embedded type software dynamic testing with respect to AD / DA use case execution sufficiency is improved finally.

Description

technical field [0001] The invention belongs to a method for testing embedded software, and in particular relates to a method for measuring the adequacy of the test in the test. The method is applied to the AD / DA interface test of the embedded software, thereby ensuring the test of the embedded software interface. sufficiency. Background technique [0002] In recent years, with the rapid improvement of digitization and intelligence, the proportion of embedded software in military weapons and equipment is increasing, and software quality has also become a key factor affecting the quality of models. In the process of weapon equipment development, finalization, delivery and acceptance, dynamic testing is a key link to verify software functions, find software problems, and improve software quality. core work. However, since the test environment focuses on verifying the normal functions of the software, it cannot verify the software's handling of various common faults and excep...
