Automatic embedded software block box testing system and method

Abstract

The invention relates to the field of computers, and discloses an automatic embedded software block box testing system and method. The testing system comprises an upper computer and a lower computer. The upper computer is used for automatically generating a testing script and establishing a simulation model of a system cross-linked with a tested system, the simulation model and the tested system are connected through the lower computer, and after a testing order is received, the testing script corresponding to the testing order is called to the lower computer. The lower computer is used for testing the tested system according to the testing script and sending testing data of the tested system to the upper computer. The testing system can automatically generate the testing script, testing efficiency is improved, the tested system is brought into a real system environment, the tested system is connected with the system cross-linked with the tested system, the integral function testing is carried out on the tested system based on a closed loop testing method, and the testing result is real and accurate.

Description

technical field [0001] The invention relates to the field of computers, in particular to an embedded software black-box automatic testing system and testing method. Background technique [0002] Since the embedded system itself has the following characteristics, such as high real-time performance, insufficient memory, few I / O channels, expensive development tools, and closely related to hardware, etc., the testing of embedded systems is different from the testing strategy of general commercial software. There is a big difference. In particular, a single embedded system needs to be cross-linked with other subsystems through various field buses (such as CAN, 1553B, 429, etc.) or I (Input, input) / O (Output, output) interfaces to form a large system that actually works. The traditional test method for embedded system is to use open-loop test and manual test method to test. The open-loop test regards the embedded system under test as an isolated subsystem. The system under tes...

AI Technical Summary

Problems solved by technology

If the embedded system under test is a subsystem in a large system, it cannot be tested as a whole by open-loop testing, and the test results obtained by such a test method are inaccurate

[0003] In addition, manual testing requires testers to be very familiar with relevant scripting languages, and using scripting languages ​​to manually write relevant use case scripts greatly reduces testing efficiency, and cannot meet the real-time performance, security and reliability required by embedded software

Testers also need to manually write test reports based on test results, which also reduces work efficiency to a certain extent
