Embodiment

[0094] Take the electromechanical core processor (EMP) of the electromechanical management system (EMS) of a certain type of aircraft as an example. The EMP airborne software is a multi-partition airborne application software based on the Wind River VxWorks AE653 operating system. Mainly completed: 1. Data acquisition and status monitoring of electromechanical control systems; 2. Comprehensive processing of electromechanical control system failure alarms; 3 Executing part of electromechanical control system control and management functions; 4 Management of data transmission between electromechanical control systems; 5 .Using virtual instrument technology to display configuration information, current status, parameters, prompts and alarm information of each electromechanical control system on the display of the avionics system; 6. Maintenance and management functions such as storage and display of electromechanical control system fault data and BIT .

Abstract

The invention belongs to the field of airborne software testing. The invention provides a multi-partition multi-version airborne application software test case reuse method. According to the technical scheme, the method comprises the following steps: (1) establishing a test case reuse model according to test requirements, a test basic version, a to-be-tested version and a change influence domain; (2) extracting common test requirements of different software versions in the same partition according to the test case reuse model established in the step (1), and establishing a test case library; (3) extracting common test requirements of different partitions according to the test case reuse model established in the step (1), and establishing a test case library; and (4) executing the step (1) and the step (3) on updated version software, and updating the test case library. The invention is suitable for reusing the test cases among multiple versions of the multi-partition airborne application software and meeting the test requirement that different partitions share the same test.

Description

technical field [0001] The invention belongs to the field of airborne software testing. 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 aviation functional module must have an exclusive set of computing resources and communication interfaces,...
