For another example, when the test piece 30 is traction control system software and the test is intended to test the logic function of application software, since the traction control system generally does not communicate with other on-board devices directly, but communicates indirectly through a network, the device simulation model 11 may select only the network control system simulation model 118, and the environment simulation model 12 may select the grid simulation model 121.
In an embodiment, the test management unit 14 in the upper computer 10 is configured to determine a test scheme according to different test pieces and test purposes, where the test scheme includes at least two test cases and a test sequence of each test case, import a network communication protocol corresponding to a test case from a pre-stored network communication protocol according to the test scheme, schedule the device simulation model 11 and/or the environment simulation model 12 corresponding to the test case, control the test execution unit 15 to execute a test, and receive a test result of the test execution unit 15. The test sequence is the execution sequence of the test cases and is determined by the execution sequence of the actual running of the train. For example, for testing of network control system software, a power grid simulation model and a traction control system simulation model may be selected, and test cases of related functions and sequences such as train initial operation, pantograph control, contactor control and the like are designed. The method includes the steps that a test case is realized based on a network communication protocol, signals defined in the network communication protocol are variable names in the test case, for example, for a traction instruction to apply the test case, corresponding signals in the network communication protocol need to be extracted, then values are assigned to the signals, and the signal values are transmitted, so that a traction instruction applying function is realized.
The test management unit 14 is also used for triggering an alarm when an abnormality occurs; and is also used for counting, evaluating and forming a test report according to the test result fed back by the test execution unit 15. The statistical results may include the following: and scheduling XX use cases in total, passing XX use cases, not executing XX use cases and the like. The test management unit 14 further calculates a test case passing rate, compares the predefined reference test case passing rate with the calculated actual test case passing rate, and if the actual test case passing rate is greater than the predefined reference test case passing rate, evaluates that the test passes. The report content of the finally generated test report may include: the method comprises the following steps of testing objects, testing time, total number statistics of test cases, case statistics of passing tests, case statistics of failing tests, test evaluation conclusion and the like.
The test execution unit 15 is configured to invoke a test case interface based on the trigger control of the test management unit 14, run the device simulation model 11 and the environment simulation model 12 scheduled by the test management unit 14 according to the test scheme determined by the test management unit 14, sequentially execute the test cases by using a modeling method such as a state diagram or a method of embedding a python script, test the test piece 30, obtain the running data of the test piece 30, monitor for test anomalies, generate a test log, and feed back the test log and the running data of the test piece 30 as test results to the test management unit 14.
The data interaction between the test execution unit 15 and the device simulation model 11, the environment simulation model 12 and the tested piece 30 is divided into two cases, in one case, the test execution unit 15 sends the instruction and the data parameter of the device simulation model 11 and/or the environment simulation model 12 to the tested piece 30 through the corresponding protocol interface in the communication conversion unit 21 in real time, so that the tested piece 30 runs based on the received instruction and parameter, and the tested piece 30 feeds back the running data to the test execution unit 15 through the communication conversion unit 21. For example, the data of the door system simulation model 114 is transmitted to the door system device as the test piece 30 through the RS485 interface of the communication conversion unit 21. In another case, for example, the test purpose is to obtain the status data of the test piece 30, such as a speed value, a rotation speed value, etc., the test execution unit 15 obtains the status data of the test piece 30 directly through the communication conversion unit 21.
The test execution unit 15 executes the test on each test case, judges the test result, when the test result is consistent with the expected result, judges the test to be passed, and when the test result is inconsistent with the expected result, judges the test result to be abnormal, executes an abnormal alarm to remind a tester to analyze whether the abnormality is true, continue the next test, or stop the test. And after the test is finished, a test log is generated based on the execution process and the test result of each test case, so that a tester can analyze the test process based on the test result.
As shown in fig. 4, which is another schematic structural diagram of the test system of the vehicle-mounted application software according to the embodiment of the present invention, in this embodiment, the upper computer 10 may further include an image recognition unit 13, configured to capture an image of the test operation in real time, and perform one or more of primitive recognition, character recognition, and color recognition on the captured image.
In the testing process, the image recognition unit 13 captures an image of a test run displayed by a human-computer display interface unit, such as a display, in real time and analyzes the image, the analyzing process includes performing primitive recognition, character recognition and color recognition on the captured image, the analysis result may include primitives, characters and colors of the image, for example, the analysis result may be running data, and then sends the analysis result to the test execution unit 15, the test execution unit 15 compares the recognition result of the image recognition unit 13 with an expected result of the test design (for example, compares the running data with preset reference running data), if the analysis result is consistent with the expected result, the test is determined to be passed, and if the analysis result is inconsistent with the expected result, the test result is determined to be not passed. Without the image recognition unit 13, the test execution unit 15 may directly acquire the operation data of the test and compare the acquired operation data with the reference operation data.
In one embodiment, the test management unit 14 also schedules the image recognition unit 13, and the test execution unit 15 determines whether the test result passes according to the recognition result of the image recognition unit 13.
Specifically, the communication conversion unit 21 of the input/output module 20 is configured to perform conversion between the in-vehicle network and the test object network when the test execution unit 15 communicates with the test object 30. The communication conversion unit 21 supports communication conversion between the ethernet and the vehicle-mounted network, and includes MVB, WTB, TRDP, RS232, RS485, RS422, CAN, Lonworks, and current loop.
The power supply unit 22 is connected with the test device 30 and the communication conversion unit 21 through power output connectors, and is used for supplying power to the test device 30, and can provide multiple groups of adjustable power supplies including DC5V, DC12V, DC24V, DC110V and the like.
By selecting different equipment simulation models, environment simulation models and image recognition units, the designed test cases are different from the executed test cases, and the test of single system software and the combined test of multiple system software can be realized. For example: the test of the network control system software, because of including all networking devices related to the network control logic, needs to choose the simulation model of all networking devices; for the joint test of the network and the traction transmission control system software, because the transmission control system belongs to a real object to be tested, a traction control system simulation unit does not need to be selected; for debugging of the network equipment of the whole train, all the network equipment are the object to be tested, so that a network equipment simulation model does not need to be selected.
The test system of the vehicle-mounted application software provided by the invention can realize ground combined debugging of a train network and matched electronic equipment and ground interface test of other matched electronic equipment controlled by the network system and the network by designing a test scheme through the upper computer and testing a test piece through the input and output module so as to meet the requirements of train trial-manufacture research and batch production delivery test.
As shown in fig. 5, a flowchart of a method for testing vehicle application software according to an embodiment of the present invention is provided, where the method is executed by the system for testing vehicle application software according to the embodiment shown in fig. 4, and the method may include the following steps:
In this embodiment, the test sequence of the test case is determined based on the actual sequence of train operation.
In this embodiment, as described with reference to fig. 1, the test piece 30 is first connected to the communication conversion unit 21 through the communication signal connector, so as to connect the test piece 30 to the upper computer 10. For example, when the tested device 30 is network control system software, the central control unit of the network control system needs to be connected to the communication conversion unit 21 through an MVB (multifunction vehicle Bus) communication signal connector, so as to connect the tested device 30 (the central control unit of the network control system) to the upper computer 10. And the test piece 30 is connected to the power supply providing unit 22, and the power supply output is adjusted to meet the input power supply requirement of the test piece 30, if the test piece 30 is the traction system equipment software of the vehicle, and the traction system equipment software needs the DC110V power supply, the traction system equipment software is connected with the output end of the DC110V power supply of the power supply providing unit 22, so as to provide the DC110V power supply for the traction system equipment software.
In this step, the test management unit 14 of the upper computer 10 specifically determines the test scenario based on the test piece and the test purpose.
And 102, controlling the test piece to execute the test case according to the test sequence.
Specifically, in this step, a network communication protocol corresponding to the test case is imported from a pre-stored network communication protocol according to the test scheme, a device simulation model, an environment simulation model and an image recognition unit corresponding to the test case are scheduled, and the test execution unit 15 is controlled to execute the test. The test execution unit 15 calls the test case interface, controls the device simulation model and the environment simulation model to perform data communication with the test piece according to the test scheme, executes the test case based on the test sequence, obtains the operation data of the test piece 30, and generates a test log according to the operation data of the data communication.
And 103, generating a test log based on the test data of the data communication.
Referring to the description in the above embodiment, the device simulation model 11 and the environment simulation model 12 to be scheduled are not necessarily the same according to different test cases.
In this step, the test execution unit 15 executes the test cases according to the test sequence by using a state diagram modeling method or a method of embedding a python script.
In an embodiment, the test execution unit 15 triggers test execution to send the instructions and data parameters in the device simulation model 11 and the environment simulation model 12 to the test piece 30 through corresponding protocol interfaces in the communication conversion unit 21 in real time, for example, the data of the door system simulation model 114 is sent to the door system device software as the test piece 30 through an RS485 interface. After the test piece 30 receives the instruction and the data parameters sent by the upper computer 10, the test piece 30 performs testing according to the corresponding functional logic requirements, and outputs the operation data to the communication conversion unit 21, the man-machine interface display unit captures and displays the communication data and the operation data, the test execution unit 15 compares the actual operation data with the pre-stored reference data to obtain the conclusion whether the test is passed or not, and records the test execution result to form a test log so as to analyze the test process and locate problems.
