Automatic detection method of testing scripts for rail transit vehicle-mounted controller software

Abstract

The present invention relates to an automatic detection method of testing scripts for rail transit vehicle-mounted controller software, comprising the following steps of (S101) loading the testing scripts and primarily inspecting the testing scripts; (S102) analyzing the testing scripts primarily inspected in the step (S101); (S103) modeling demands of the vehicle-mounted controller software, using periodic data obtained by analytic expansion in the step (S102) as an input, and simulating a demand model; and (S104) comparing results, and comparing and analyzing the model simulation output obtained in the step (S103) and an expected result designed by the test scripts in the step (S101) so as to inspect correctness of the test scripts. Compared with the prior art, the automatic detection method has the advantages that the blank of verification and detection automation of the test scripts for the rail transit vehicle-mounted controller software is filled in, and substantial detection of correctness of contents of the test scripts by computers can be truly achieved.

Description

technical field [0001] The invention relates to a test script detection method, in particular to an automatic test script detection method for rail transit vehicle controller software. Background technique [0002] With the rapid development of my country's rail transit industry, on-board controller software is being updated more and more frequently, and its functions are becoming more and more complex. At the same time, the pressure on related software testing work is also increasing. Script-based automated testing has the characteristics of good reproducibility and high reusability, and is especially suitable for regression testing. It is an effective means to reduce the pressure of test execution and improve test efficiency. However, the quality and correctness of test scripts is the core of script-based automated testing, which will directly affect the quality and reliability of testing. At present, the quality of test scripts is mainly guaranteed by means of manual in...

Problems solved by technology

Because of the particularity of the vehicle controller software test, the execution of the script is not compiled, and it is directly interpreted and executed. Therefore, the detection of the test script is currently done manually

[0004] This method of manual detection of test scripts has the following disadvantages: (1) Due to manual detection, there may be cases where the inspection is not in place or omissions occur, resulting in incomplete inspection of test scripts, resulting in security risks

(2) The characteristics of the on-board controller software test have resulted in a large number of test scripts and a large number of script file contents. Manual testing will inevitably affect work efficiency and will take a lot of time, resulting in increased cost of change implementation
