Embodiment Construction

[0034] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0035] Under the background of the development of IMA and high-security partitioned airborne operating systems, the architecture of airborne software has undergone major changes. The degree of integration, complexity, and software scale of partitioned application software has increased sharply, as well as high-standard quality requirements, which make software testing work exist. Many difficulties.

[0036] At present, the testing work of IMA's multi-partition large-scale and complex integrated system airborne software is mainly based on independent software configuration ite...

Abstract

The embodiment of the invention discloses a method for testing multi-partition airborne software, which comprises the following steps of: performing type division on partition application software according to the application field and task characteristics of the partition application software; according to the types of the partition application software, testing the partition application softwareby adopting a test mode corresponding to the types, and testing the partition operating system of each partition, wherein a test excitation path and a test output path are formulated for test modes adopted by different types of partition application software, and the test object comprises each layer and partition application software through which the path passes. According to the embodiment of the invention, the test problem of multi-application type software of multi-partition large-scale complex integrated system airborne software is solved, the test requirements of different application type software on IMA and high-security partition airborne operation can be met, and the method is suitable for unit component configuration items and system tests and has good generalization performance.

Description

technical field [0001] This application relates to but not limited to the technical field of airborne software testing, especially a method for testing multi-partitioned airborne software. Background technique [0002] The Integrated Modular Avionics (IMA) of avionics systems makes it an inevitable development trend for a set of airborne computer physical platforms to undertake multiple application fields, multiple systems, and different types of tasks. In order to solve the fault isolation and information security problems brought about by IMA, the existing high-security airborne operating systems have adopted partition mechanisms to provide inter-partition isolation and inter-partition communication capabilities. Typical partition operating systems, such as Wind River VxWorksAE653 and my country's independent Property right Tianmai system AcoreOS 653. [0003] Compared with the traditional Federated Avionics Architectures (FAA, Federated Avionics Architectures), each aviat...
