Keyword drive-based automatic test method of urban rail drive control units

Abstract

The invention discloses a keyword drive-based automatic test method of urban rail drive control units. The method comprises the following steps: determining a keyword set of a tested object; compiling a test script according to the keyword set; establishing a keyword drive-based automatic test frame and constructing a top layer test data table, a middle layer test data table, a bottom layer test data table and a keyword support library for the automatic test frame; inputting the test script into the automatic test frame, successively calling drives of the layers to inquire the contents in the test data tables on the basis of a test drive engine of the automatic test frame in allusion to each objective keyword in the test script; and calling bottom layer functions of the keyword support library to output a script bottom layer execution sequence file and directly and interactively carrying out test with the tested object. The keyword drive-based automatic test method of urban rail drive control units has the advantages of reducing the skill requirement for the test personnel, being high in test script reusability and good in maintainability and portability, shortening the test script development and maintenance time and reducing the test script development and maintenance cost.

Description

technical field [0001] The present invention relates to the software testing technology of the drive control unit (DriveControlUnit, referred to as DCU, a controller on the traction converter used in the field of rail transit) of urban rail, in particular to a key-based driven urban rail drive control unit Automated testing methods. Background technique [0002] As one of the key equipment of urban rail vehicles, the transmission control unit (DCU) is known as the "heart" of urban rail vehicles. When implementing precise control on the traction converter, the logic control function of the DCU is very important. It undertakes the important functions of traction system management and communication, and directly affects the function, safety and efficiency of the traction converter. Therefore, software testing of the logic control software of the DCU has also become an important means to ensure the quality of the software and improve the reliability of the DCU. [0003] With t...

AI Technical Summary

Problems solved by technology

At present, DCU testing by manual testing is becoming more and more challenging, due to the following disadvantages: low efficiency of manual testing, low efficiency of regression testing, heavy workload of writing test cases, long testing cycle and insufficient testing

However, this technical solution has disadvantages in terms of script development and maintenance: First, testers can only use the script development environment that comes with the test tool to develop scripts, and testers need to have certain programming skills to complete script development. The developed test scripts There is no separation of test data and test business logic in the test, resulting in the need to change the test script once the test needs to be changed, the script maintenance workload is heavy, and the maintainability is poor; Poor usability, test scripts between similar projects cannot be directly borrowed or maintained, the difficulty of maintenance and transformation is comparable to that of redeveloping a set of test scripts, poor maintainability
