Automatic closed loop test system of real-time embedded software

Abstract

The invention relates to an automatic closed loop test system of real-time embedded software. The system comprises an upper computer, a lower computer connected with the upper computer, and a real-time embedded system to be tested which is connected with the lower computer. The upper computer comprises a test configuration module, a test program generation module and a data communication module; the lower computer comprises a task scheduling module, a test execution engine and an I / O interface support program module; and the test execution engine further comprises a preprocessing module, an on-line processing module and a feedback processing module. In the system, the test execution engine is embedded into a test platform, a test drive module is integrated with the test execution engine ofthe system so that execution described by the test can drive automatic real-time running of the test.

Description

technical field [0001] This system belongs to the field of real-time embedded software automation testing. Background technique [0002] With the development of science and technology, real-time embedded software has been used more and more in important fields such as aerospace, weapons, ships, automobiles, medical equipment, electric power, communications, etc., and realizes more and more important functions. As a logical product of human beings, software must have design and development flaws. According to statistics, in real-time embedded devices, failures caused by software account for 70-80% of the total failures, and the subsequent accidents have caused huge losses, such as: the crash of the ESA Ariane rocket, North America A major power outage, and a software failure on the American Mars rover Spirit. Therefore, how to improve the reliability of real-time embedded software has become an urgent problem to be solved. [0003] Real-time embedded software is closely re...

AI Technical Summary

Problems solved by technology

[0003] Real-time embedded software is closely related to hardware, and usually has high real-time requirements, which makes conventional testing methods unable to meet the requirements of embedded software testing. Automated testing can ensure the efficiency and timing stability of real-time embedded software testing , reliable, has become a hot spot in the field of real-time embedded software testing

Although software test automation technology has been developed for many years and has achieved many research results, there are few automated closed-loop testing methods for real-time embedded software.
