Vehicle-mounted controller software testing system and method based on behavior driving scripts

Abstract

The invention relates to a vehicle-mounted controller software testing system and method based on behavior driving scripts. The vehicle-mounted controller software testing system comprises a behaviordriving script parsing module M1 for parsing testing scripts based on behavior driving and generating machine instruction inputs identified by the testing system, a test execution module M2 for usingmachine instructions produced by the behavior driving script parsing module M1 as inputs, simulating messages and data of peripheral interfaces of tested vehicle-mounted controller software in real time, providing stimulation feedback for the tested vehicle-mounted controller software and monitoring the running state of the testing system in real time, a testing result recording and analyzing module M3 for recording output data produced in the running process of the tested vehicle-mounted controller software and running data of the testing system, judging script sentences according to resultsgiven by the behavior driving script parsing module M1 and judging whether testing is passed or not. Compared with the prior art, the vehicle-mounted controller software testing system has the advantages of being easy to read and master, friendly in man-machine interaction and the like.

Description

technical field [0001] The invention relates to a rail transit on-board controller software testing system and method, in particular to a behavior-driven script-based on-board controller software testing system and method. Background technique [0002] With the rapid development of my country's rail transit industry, the functional requirements of on-board controller software are becoming increasingly complex, and the testing of this type of highly reliable embedded software is an important means to verify software functions and confirm that the software has sufficient security protection capabilities. The test results It is also an important basis for safety assessment of such software. High-reliability embedded software requires test cases to have 100% coverage of software requirements, covering all possible normal and abnormal scenarios. Therefore, the workload of testing is huge, and it is difficult to fully cover it only by manual means, and the cost is considerable. ...
