At present, a manual testing mode needs a lot of vehicle control equipment hardware support, pressure testing cannot be achieved, and the problems of low testing efficiency, high testing cost, poor reliability of testing results and the like exist.
To facilitate understanding of the embodiment, a car machine testing method disclosed in the embodiment of the present invention is first described in detail, where the method is applied to a car machine testing system, the car machine testing system is in communication connection with a car networking terminal of a car machine to be tested, and a graphical User Interface is provided through the car networking terminal, where the graphical User Interface is also UI (User Interface Design), and the graphical User Interface may provide multiple virtual controls, and the virtual controls may be menu controls or function controls, and the car machine testing method provided in the embodiment of the present invention may be applied to any vehicle equipped with a car networking terminal, and refer to a flowchart of the car machine testing method shown in fig. 1, where the method mainly includes the following steps S102 to S108:
and S102, acquiring test configuration parameters corresponding to the vehicle machine to be tested. The test configuration parameters at least include test item description parameters and expected feedback values, the test item description parameters may include a test item name corresponding to at least one vehicle machine function, a control identifier, an interface identifier where the control is located, and a control operation type, the control operation type may include clicking, moving, and the like, and the expected feedback values are used for representing object states expected to be fed back by the vehicle machine to be tested. In an embodiment, a parameter configuration table may be provided for a tester, the tester may fill test configuration parameters in the parameter configuration table, and the in-vehicle test system may further provide an upload channel for the tester, so as to obtain the parameter configuration table uploaded by the tester, and read the test configuration parameters in the parameter configuration table.
And step S104, according to the test item description parameters, executing simulation trigger operation aiming at the target operation position in the graphical user interface so as to trigger the vehicle machine to be tested to execute the vehicle machine function corresponding to the target operation position. And the target operation position can display a function control corresponding to the car machine function. In an implementation manner, a target interface corresponding to an interface identifier where a control is located may be provided through a graphical user interface, a function control corresponding to the control identifier is displayed on the target interface, and if the control operation type corresponding to the function control is a click, it may be determined that the simulated trigger operation is a click operation, and an automatic click program is used to click a target operation position where the function control is located, so as to trigger the vehicle machine to be tested to execute a corresponding vehicle machine function.
And S106, when the function execution of the car machine is finished, analyzing a feedback signal generated by the car machine to be tested to obtain a test feedback value. The feedback signal may be a Controller Area Network (CAN) signal, the CAN signal at least includes a CAN message, and the test feedback value is used to represent an object state fed back by the vehicle device under test. In an implementation mode, the CAN signal generated by the vehicle machine to be tested CAN be monitored and collected in real time, and the CAN message is analyzed by using a preset communication protocol to obtain a test feedback value.
And S108, determining a test result corresponding to the vehicle machine to be tested based on the expected feedback value and the test feedback value. The test result may include test success or test failure, and may also include a reason for the test failure, an execution performance level, a stress performance level, and the like, and the test result may be provided to a tester in a report form. In an embodiment, whether the expected feedback value is consistent with the test feedback value or not can be compared, and if not, the test failure of the vehicle machine to be tested is determined. In addition, a time condition can be set, for example, timing is started from the execution of the simulation trigger operation on the target operation position, and the timing is stopped when the feedback signal is acquired, and if the timing duration is longer than the preset duration, even if the expected feedback value is consistent with the test feedback value, the test failure of the vehicle machine to be tested can be determined.
According to the car machine testing method provided by the embodiment of the invention, the simulation trigger operation can be executed according to the test item description parameters aiming at the target operation position in the graphical user interface, the feedback signal generated by the car machine to be tested is analyzed to obtain the test feedback value, and the test result is obtained on the basis of the expected feedback value and the test feedback value.
In an embodiment, the vehicle testing method is applied to a vehicle testing system, and for convenience of understanding, referring to a schematic structural diagram of the vehicle testing system shown in fig. 2, the vehicle testing system includes a testing cloud platform, an automatic testing platform and a vehicle monitoring platform, both the automatic testing platform and the vehicle monitoring platform are in communication connection with the testing cloud platform, and the automatic testing platform and the vehicle monitoring platform are also in communication connection with a vehicle networking terminal. The test cloud platform is used for acquiring test configuration parameters corresponding to the vehicle machine to be tested and determining a test result corresponding to the vehicle machine to be tested based on the expected feedback value and the test feedback value; the automatic test platform is used for executing simulation trigger operation aiming at a target operation position in the graphical user interface; the vehicle monitoring platform is used for acquiring and analyzing a feedback signal generated by the vehicle machine to be tested to obtain a test feedback value.
On the basis, when the vehicle testing system executes the step of obtaining the test configuration parameters corresponding to the vehicle to be tested, the parameter configuration table can be provided through the testing cloud platform, the parameter configuration table can be provided by software developers, the testers can conveniently and quickly fill the test configuration parameters on the testing cloud platform, and the test configuration parameters are sent to the automatic testing platform through the testing cloud platform after being filled. Illustratively, the test configuration parameters include a test item name corresponding to at least one test item (which may be understood as a car machine function), a control identifier (i.e., an Identity Document (ID), a button/ID), an interface identifier where the control is located (i.e., an object package name, an interface name, a package name/. avidity), a control operation type (i.e., move/click), an expected feedback value (i.e., an object state), and a test number of each test item, as shown in table 1 below:
TABLE 1
| Name of test item | button/id | Package name/. availability | move/click | Object state | Number of tests |
| Air conditioner on | B1 | A1 | click | Is opened | 10 |
| Air conditioner temperature regulation | B2 | A2 | move | 26℃ | 10 |
After receiving the test configuration parameters, the automated testing platform will execute a simulation trigger operation for the target operation position in the graphical user interface according to the test item description parameters, and in an embodiment, the automated testing platform may execute step S104 according to the following (1) to (3):
(1) and triggering the graphical user interface to provide a target interface corresponding to the interface identification where the control is located. Taking table 1 as an example, the automated testing platform may trigger a graphical user interface of the car networking terminal to provide a target interface corresponding to an interface identifier a1 where a control is located, where a virtual control displayed on the target interface at least includes an air conditioner on-off control.
(2) And determining a target operation position from the target interface according to the control identification and the preset mapping relation. The preset mapping relation comprises a mapping relation between the control identification and the operation position. Continuing with table 1 as an example, a target operation position corresponding to the control identifier B1 may be searched in the preset mapping relationship, an air conditioner on-off control is displayed at the target operation position of the target interface, and the target operation position may be represented by coordinates (x, y).
(3) And executing the simulation trigger operation corresponding to the control operation type aiming at the target operation position. Continuing with table 1 as an example, the automatic test platform may use an automation program to click the target operation position to trigger the vehicle under test to control the air conditioner to be turned on.
Considering that the execution of the analog trigger operation may fail, in order to facilitate a tester to know the reason for the execution failure, the operation execution result of the analog trigger operation may be monitored, and the reason for the execution failure of the analog trigger operation may be determined when the operation execution result is the execution failure. The reason for the failure of execution may include that there is no corresponding virtual control in the target interface, the virtual control is inoperable, the automation program crashes, an execution timeout, or others. For example, when the control identifier is not matched with the interface identifier where the control is located, a situation that there is no corresponding virtual control in the target interface may occur; when the virtual control is in a locked state, such as when the air conditioner is not turned on, the air conditioner temperature adjusting control is in a locked state, and the situation that the virtual control is not operable occurs.
Please refer to fig. 2, when the simulation trigger operation is successfully executed, the car machine to be tested executes the car machine function, and generates a CAN signal when the car machine function is completely executed, the vehicle monitoring platform CAN collect the CAN signal of the car networking terminal through the CAN bus, analyze the CAN message according to the preset communication protocol to obtain a test feedback value, and send the test feedback value to the cloud testing platform, and the cloud testing platform determines whether the car machine test is successful.
When the cloud test platform judges whether the vehicle machine test is successful, whether the expected feedback value is consistent with the test feedback value can be judged; if so, determining that the test result corresponding to the vehicle machine to be tested is successful; and if not, determining that the test result corresponding to the vehicle machine to be tested is test failure. For example, when the expected feedback value is "air conditioner on", if the analyzed test feedback value is also "air conditioner on", it may be determined that the test is successful, and if the analyzed test feedback value is also "air conditioner off", it may be determined that the test is failed.
In addition, the testing cloud platform can also judge whether the vehicle machine test is successful or not based on the function execution duration (namely, the timing duration). For exemplary purposes, see steps 1 through 3 below:
step 1, judging whether a feedback signal generated by a vehicle machine to be tested is collected within a preset time length. If yes, executing step 2; if not, step 3 is executed. In an embodiment, whether a feedback signal generated by a vehicle machine to be tested is collected within a preset time period can be judged according to the following steps 1.1 to 1.2:
and 1.1, recording the operation execution time of the simulation trigger operation and the acquisition time of the feedback signal. In one embodiment, the operation execution time t1 of the simulation trigger operation may be recorded by the automated testing platform and sent to the testing cloud platform, and the collection time t2 of the CAN signal is collected by the vehicle monitoring platform and returned to the testing cloud platform.
And step 1.2, calculating the time difference between the operation execution time and the acquisition time to obtain the function execution duration required by the vehicle machine to be tested to execute the vehicle machine function. In one embodiment, the cloud test platform may calculate the time difference t 0-t 2-t1, which is the time duration of the function execution, t 0. If the function execution time period t0 is less than or equal to the preset time period, determining that the feedback signal is acquired within the preset time period; otherwise, it is determined that the feedback signal is not acquired within the preset time.
And 2, determining that the test result corresponding to the vehicle machine to be tested is successful. For example, assuming that the preset time duration is 10 seconds, if the function execution time duration is less than or equal to 10 seconds, the test result is determined to be successful.
And step 3, determining that the test result corresponding to the vehicle machine to be tested is test failure. For example, assuming that the preset time duration is 10 seconds, if the function execution time duration exceeds 10 seconds, the test result is determined to be successful.
For convenience of understanding, an embodiment of the present invention further provides an application example of a car machine testing method, and referring to a flow diagram of another car machine testing method shown in fig. 3, the method mainly includes the following steps S302 to S318:
step S302, test configuration parameters are obtained through the test cloud platform.
And step S304, simulating and triggering a target operation position in a graphical user interface of the Internet of vehicles terminal through the automatic test platform.
And step S306, checking whether the click operation is successfully executed through the automatic test platform. If yes, go to step S308; if not, step S316 is performed.
And step S308, collecting the CAN signal through the vehicle monitoring platform, and judging whether the function execution time is overtime or not through the test cloud platform. If yes, go to step S316; if not, step S310 is performed.
And step S310, analyzing the CAN message through the vehicle monitoring platform to obtain a test feedback value.
Step S312, determining whether the test feedback value is consistent with the expected feedback value through the test cloud platform. If yes, go to step S314; if not, step S316 is performed.
Step S314, determining that the test is successful.
Step S316, it is determined that the test failed.
And step S318, generating a test report through the test cloud platform and storing a test log. In practical application, by generating the test report and storing the test log, the tester can conveniently check and analyze the problems of the vehicle machine to be tested, so that the problem solving efficiency of the tester is improved.
In an embodiment, the function execution duration may also be used to evaluate the execution performance and the pressure performance of the car machine to be tested, and embodiments of the present invention respectively provide an implementation manner for evaluating the execution performance and the pressure performance, which is as follows:
in a first mode, the execution performance is evaluated: (1) calculating the duration and the value of the function execution duration of each vehicle machine function executed by the vehicle machine to be tested; (2) and determining a target execution performance grade corresponding to the vehicle machine to be tested from preset execution performance grades according to the duration and the value. In specific implementation, a software performance standard may be configured in advance, and the software performance standard may embody the performance of the single function executed by the vehicle machine to be tested, for example, the software performance standard specifies that the function execution duration of a certain vehicle machine function is in a range of 0 to 3s corresponding to an excellent level, the function execution duration is in a range of 3s to 5s corresponding to a qualified level, and the function execution duration is greater than 5s corresponding to an unqualified level.
In one embodiment, the automatic test platform is used for continuously testing a plurality of vehicle machine functions, counting the function execution time of each vehicle machine function, and evaluating the execution performance of the vehicle machine integrated service to be tested according to the time length and the value of the function execution time length. For example, assuming that two functions of "air conditioner on" and "air conditioner temperature adjustment" are continuously executed, the corresponding relationship between the total time consumption of the two functions and the execution performance level is pre-configured according to the software performance standard, and the target execution performance level corresponding to the time duration and the value is found out based on the corresponding relationship, and the target execution performance level can embody the execution performance of the integrated service of the vehicle machine to be tested.
Mode two, the pressure performance was evaluated: (1) for each car machine function, determining the execution overtime times according to the preset time length and the function execution time length of the car machine to be tested for executing the car machine function each time; (2) and determining a target pressure performance grade corresponding to the vehicle machine to be tested from the preset pressure performance grades according to the execution overtime times. The pressure performance can represent the stability of the hardware of the vehicle to be tested, and the execution overtime times, namely the times that the function execution duration is greater than the preset time, are obtained. In an embodiment, the test configuration parameters further include the number of times of testing each car machine function, and the target pressure performance level corresponding to the car machine to be tested is detected through a large number of repetitive operations. For example, whether the function execution time length for executing the vehicle machine function each time exceeds the preset time length or not can be judged, the times exceeding the preset time length are counted to obtain the execution overtime times, and the corresponding target pressure performance grade can be found based on the corresponding relation between the preset execution overtime times and the pressure performance grade.
For example, according to the design life of the car machine to be tested for m years, the number of times of use of the car machine to be tested per day n is estimated, the car machine function of the car machine to be tested is subjected to life pressure test for m times of 365 times of n times of 5 times, and the automatic test platform can analyze the reason of test failure through the buried points according to the pressure stability test, so that a tester can solve the stability problem of the car machine to be tested before mass production. Compared with a manual testing mode in the prior art, the method and the device for testing the vehicle network terminal can test the functions of a single vehicle machine for thousands of times through the automatic testing platform, and can detect the stability of the vehicle network terminal in long-time running.
In order to facilitate a tester to find a reason for a test failure, the car networking terminal provided in the embodiment of the present invention is configured with at least one processing logic corresponding to a car machine function, each processing logic is added with a test embedded point, and the test embedded point is configured to instruct the car networking terminal to generate a test log corresponding to the processing logic when execution of the processing logic is completed. For example, referring to an application scenario diagram of a car machine testing method shown in fig. 4, fig. 4 illustrates that the car machine function includes N processing logics, test embedded points are added between each processing logic, and the number of the test embedded points is N.
On the basis of fig. 4, an embodiment of the present invention further provides an implementation manner of determining a target processing logic that affects performance of a vehicle device under test, which is shown in the following (a) to (d):
and (I) judging whether a test log corresponding to each processing logic is received. If yes, executing (two); if not, (IV) is performed. With continuing reference to fig. 4, fig. 4 illustrates that the automated testing platform simulates clicking or sliding a target operation position in a graphical user interface, the car networking terminal executes processing logic corresponding to the car machine function, a test log corresponding to the corresponding processing logic is generated each time the processing logic is executed to a test burying point, and the vehicle monitoring platform receives the test log through the CAN bus, so as to determine whether the test log corresponding to each processing logic is received through the vehicle monitoring terminal. Optionally, the vehicle monitoring platform and the vehicle networking terminal may establish a communication connection through a PCAN (CAN to USB interface).
And secondly, determining the logic execution time length of each processing logic according to the test log corresponding to each processing logic. In a specific implementation, the test log records the execution start time and the execution end time of the corresponding processing logic, so that the logic execution time length to each processing logic can be determined.
And thirdly, determining target processing logic influencing the performance of the vehicle machine to be tested from the processing logic according to the logic execution duration. For example, if the logic execution duration of processing logic 1 is greater than the specified duration, then processing logic 1 may be determined as the target processing logic; or selecting one or more processing logics with longer logic execution time length as the target processing logic according to the sequence of the logic execution time lengths from large to small.
And (IV) if the test log corresponding to the processing logic is not received, determining the processing logic as the target processing logic influencing the performance of the vehicle machine to be tested. For example, if the processing logic 2 fails to execute, which results in that the test log is not successfully generated, at this time, the vehicle monitoring platform cannot acquire the test log corresponding to the processing logic 2, and at this time, the processing logic 2 may be directly determined as the target processing logic.
The target processing logic, namely the influence factors of the vehicle machine performance, can determine the processing logic influencing the execution performance in the vehicle machine function by analyzing the test logs corresponding to the test embedded points. In an optional implementation mode, a function report, a performance report, a stability report and a related log can be generated, so that testers can optimize the functions of the vehicle machine and improve the soundness of software functions conveniently, and can also optimize the performance of software and the stability of the software conveniently, and the service life of the software is prolonged.
