Method and system for testing vehicle-mounted software of train

Abstract

The invention relates to a method for testing vehicle-mounted software of a train. The method is characterized by comprising the following steps of: peeling off a bottom layer hardware driver of the vehicle-mounted software and upper layer logic operation, and establishing the bottom layer hardware driver based on a target operating system; transplanting the upper layer logic operation to a platform of the target operating system, and constructing software to be tested together with the driver based on the operating system; calling and running a test example; acquiring associated equipment running data by the upper logic operation from a peripheral equipment simulator and / or real peripheral equipment through the bottom layer driver, acquiring corresponding train state simulation data through a train simulation operating platform, and generating an execution result; and judging a quality characteristic of the software to be tested according to the execution result. The invention also discloses a system for testing the vehicle-mounted software of the train. The test process is high in efficiency and standard; and the test result is accurate.

Description

technical field [0001] The invention relates to the field of software testing, in particular to a testing method and testing system for train vehicle safety control software. Background technique [0002] Software testing is a very important link to ensure software quality, so it is necessary to introduce various testing tools to improve the efficiency of software testing. For the testing of PC-based software, there are many theories, methods and tools, which are gradually becoming mature. However, in the field of software testing based on embedded platforms, because it must be oriented to a specific hardware platform, there are few effective theories and methods. Or costly. As the train control system responsible for the safety of trains, a small flaw in the safety control software on the train may threaten the safety of the train and cause huge losses of personnel and property. Therefore, it is very important to test the safety control software on the train. And from th...

AI Technical Summary

Problems solved by technology

Therefore, the vehicle-mounted software is characterized by complex control logic and a large number of test cases, which are continuously accumulated, and the time to complete a test increases geometrically.

If the vehicle software undergoes a major change, it is often necessary to mobilize more than a dozen people to conduct repeated tests, and the test method that relies on "human sea tactics" seriously affects the test efficiency

[0005] During the test, due to mainly relying on manual testing, human short-term memory is limited, and there are individual differences, resulting in different timing and sequence of giving simulated data, resulting in different test results. Using the same test case, even if problems are found , it is difficult to completely repeat the last test process, which will affect the test effect
