Test scene generating method for railway signal computer interlocking system

Abstract

The invention discloses a test scene generating method for a railway signal computer interlocking system. The method comprises the following steps that firstly, format definition is conducted on scripts for describing test scenes, wherein a three-layer XML element structure is adopted as the format of an XML file of the test scenes; secondly, all test scenes of a station yard to be tested are automatically generated, wherein elements in a second layer are used for defining names and numbers of the test scenes and types of devices to be tested, setting is conducted on test commands of elements in a third layer according to the types of the devices to be tested and correlative device types to form test commands, and the test commands are arranged in series. By means of the method, the test scenes can be precisely described, all test cases can be automatically generated according to a device comparison table of the station yard to be tested, the test efficiency can be improved, and omission and errors caused by manual testing can be effectively reduced.

Description

technical field [0001] The invention relates to a computer interlocking system, in particular to a test scene generation method for a railway signal computer interlocking system. Background technique [0002] Safety is the eternal theme of railway transportation production, and the computer interlocking system is the key system to ensure the safety of railway station trains and locomotives, so in order to ensure the safety of the system, it must be tested efficiently and fully. [0003] Due to the complexity of the interlocking system business logic relationship, manual testing has disadvantages such as insufficient testing, low testing efficiency, and high labor intensity. Automated testing can replace manual operations to achieve standardized, programmed, and simplified testing, thereby improving Improve work efficiency, shorten test time, and eliminate errors caused by manual operation. [0004] Existing research on automation testing of interlocking systems mostly focus...

AI Technical Summary

Problems solved by technology

[0006] Since the test scenario is completely dependent on the experience of the tester, whether the test cases meet the requirements of the scenario, whether the number of test cases is complete, etc., can only rely on the tester's test operation; at the same time, the test experience cannot be promoted in different stations under test ; All the testing process, the judgment of the test results, the statistics of the test results, etc., can only be done manually

In this case, the whole test process, the test period is long, the test content and results are prone to omissions and mistakes, and the test experience cannot be promoted in different tested stations.
