Referring to fig. 3, the method includes:
in step 301, a configuration file of automated test software is read.
In this step, the configuration file of the automated test software may be read by the computer terminal device. And installing automatic test software on the computer terminal equipment. The configuration file of the automatic test software comprises a test script Excel file with a fixed format, which is automatically generated by the automatic test software, and the test script Excel file is set or modified according to a demand function or a communication protocol.
For example, when a tester performs software testing, an initial test script Excel file with a fixed format can be automatically generated through automatic test software of computer terminal equipment, and setting, modification, perfection and the like are performed according to a required function or a communication protocol. The test script Excel file may include information such as an MVB communication port, and the test script information may include: port number, word offset, bit offset, signal name, preconditions, operating steps, expected results, actual results, conclusions, etc. The whole configuration file is written according to the preposition condition, the test function and other pages. At the beginning of the execution of the automatic test, the automatic test software will automatically read the configuration file to obtain all the test functions and script information.
In step 302, the function under test is selected.
In this step, the function under test selected by the tester is acquired.
In step 303, the automated test script in the configuration file is executed.
In this step, the automated test script in the configuration file is executed, that is, a new use case in the configuration file is executed.
In step 304, the generated test data is sent to the display under test.
The automatic test software constructs all port data character strings with specified length during running, firstly analyzes an automatic test script after the execution of the automatic test is started, writes data into the specified port position, sends the character strings, namely the test data to the protocol conversion module, converts the character strings into MVB protocol data by the protocol conversion module and then sends the MVB protocol data to the display to be tested, and the display to be tested responds according to the received test data.
In step 305, an interface image of the display under test responding to the test data is obtained and stored.
In this step, the interface of the display under test can be mapped to the computer terminal device by the screen splitter. Referring to fig. 5, fig. 5 is a schematic display diagram of a train display under test in a train display software testing method according to an embodiment of the invention. In fig. 5, a train number is shown, and the function menu at the bottom of the interface includes: event logging, setup, maintenance, homepage, etc., and also display speed and dc voltage on the interface.
Then, the camera equipment collects an interface image of the display to be tested responding to the test data according to the mapped interface and sends the interface image to the computer terminal equipment, and the computer terminal equipment receives and stores the interface image of the display to be tested responding to the test data sent by the camera equipment.
In step 306, the acquired interface image is matched with a preset image template.
In the step, the computer terminal equipment compares and matches the acquired interface image with the corresponding image template in the background, and judges whether the acquired interface image is consistent with the expected result.
The step can match the acquired interface image with a preset image template in a color template matching mode.
The invention relates to an automatic image identification and comparison part of automatic test software, namely a function of matching an acquired interface image with a preset image template, which can be realized by a LabVIEW (program development environment) machine vision development system. The invention can adopt a color template matching mode to complete the detection of the interface change of the display, for example, the icon, the character and the like of the interface change due to the change of the execution of the use case. The color template matching mode is mainly based on the color and space distribution characteristics of a target image, such as shape and size, and combines the color matching and gray level image pattern matching technology to quickly locate the color pattern in the image. Referring to fig. 6, a schematic diagram of a structure of a template matching program in a train display software testing method according to an embodiment of the present invention is shown. Firstly, reading an icon template image of a display into a memory, and learning information such as color, shape and the like of the icon template image; then reading the target image to be detected into an internal memory, matching the target image with the icon template image, and performing secondary verification according to the returned matching information and the position information to further ensure the matching accuracy; and finally, judging whether the detection result is successfully matched.
In step 307, it is determined whether the acquired interface image matches a preset image template, if not, step 308 is performed, and if so, step 309 is performed.
In step 308, a determination is made that the script did not execute, and step 310 is entered.
In this step, if the obtained interface image is unsuccessfully matched with the preset image template, the current script execution does not pass, that is, the present case does not pass.
In step 309, the script execution is determined to pass, and step 310 is entered.
In this step, if the obtained interface image is successfully matched with the preset image template, the current script is executed and passed, that is, the present case is passed.
In step 310, the test result and the test procedure data are saved, and the process proceeds to step 311.
In this step, the test results and test procedure data are saved.
In step 311, it is determined whether all the automation test scripts have been executed, if not, the process returns to step 303, and if yes, the process proceeds to step 312.
This step determines whether the execution of all the selected automation test scripts is completed, and if not, returns to step 303 to continue executing a new automation test script.
In step 312, the test ends.
And finishing the execution of the selected automatic test scripts and generating a test report if the execution of the automatic test scripts is finished.
After all tests are executed, the invention can automatically issue the test report and export and store the test result and the test process data by one key. The execution condition and the final result statistics of each test script are recorded in detail in the test report, so that the test personnel can conveniently perform test analysis and recording.
The invention further introduces the internal data flow of the test script execution independently. Fig. 4 is a schematic diagram of internal data flow of test software in a train display software test method according to an embodiment of the invention. As shown in fig. 4, the process of the internal data flow includes:
in step 401, test script editing is performed or a test script is imported.
In step 402, test script compilation or inspection is performed.
In step 403, the test script is automatically executed. In this step, data interaction with the protocol conversion module is involved.
In step 404, test result statistics and test reports are generated.
Fig. 7 is a schematic diagram of a test result displayed in a train monitor software testing method according to an embodiment of the invention. As shown in FIG. 7, the interface for the test results in the figure includes serial number, vehicle number, list number, input information, output information, test results, and notes.
For example, the train numbered 95 in the figure shows that the test result is OK (success); the train display device with the serial number 101 is failed, and the train display device with the serial number 102 gives an alarm. Equipment failures and equipment warnings may be displayed in different colors to alert test personnel.
From the embodiment of fig. 3 of the present invention, it can be found that:
1) the data input of the prior art method is inflexible, and brings inconvenience to test execution operators. The test execution operator must be familiar with the principle of the accompanying software, the protocol, the variable name and the like to correctly execute the use case, otherwise, errors can be caused; the scheme of the invention adopts the automatic execution of the automatic test script, does not need manual intervention, and has simple and convenient operation.

3) The prior art method has low testing efficiency. The method needs to spend several minutes for executing a simple case, and the test time for completing the whole software is very long, so the test efficiency is very low; the scheme of the invention adopts the automatic test script to automatically execute, the whole test process does not need other operations, the software automatically executes the test script, the execution time of each case is adjustable, the fastest execution of one case only needs a few seconds, the test time is greatly reduced, and the operation of testers is also reduced, so the test efficiency is high.
4) The prior art methods are not reusable. The method is completely manually operated, and the whole process is not recorded and stored, so that the reproduction of the process of finding problems and the reutilization of subsequent tests are not facilitated; the scheme of the invention saves the test process data, the format of the test script file is fixed, and the script case information is detailedly split and recorded, so that the problem reproduction and the repeated utilization of the subsequent test can be conveniently carried out, and the reusability is realized.
5) The test result of the prior art method can not be automatically identified and stored, and the output result can only be manually observed and recorded; the scheme of the invention combines the artificial intelligence technology to diagnose the display image and the fault, can be repeatedly executed, can store the test result data and has reusability.
