[0002] HIL (Hardware-in-the-Loop) testing plays a vital role in the development of automotive electronic controller systems. It can simulate controller behavior in real environments, detect potential problems in advance, and ensure system stability and performance. However, with the increase in vehicle models and controller types, the characteristics of various controllers in different vehicle models are different, requiring targeted test plans and parameter settings. However, the HIL platform resources used for HIL testing are limited, and HIL platforms from different manufacturers also have different test environments and parameter configurations. In the traditional HIL testing process, testers need to write separate test cases for each manufacturer's HIL platform based on the controller to be tested. This high degree of coupling means that if the HIL platform is replaced, the test cases need to be rewritten, which consumes a lot of testers' time and energy and is inefficient.

[0042] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0043] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0044] The main solution of the embodiment of the present application is: receiving an input test case and a HIL platform type, and obtaining parameter variables in the test case; calling a target conversion library in a preset script conversion library according to the HIL platform type, and converting the test case into a candidate test script through the target conversion library; determining a signal source address of the parameter variable based on the HIL platform type and the parameter variable, and writing the signal source address into the candidate test script to obtain a test script, wherein the signal source address is the address of the test signal generated in the HIL platform.

[0045] In the traditional HIL testing process, testers need to write separate test cases for each manufacturer's HIL platform according to the controller to be tested. This high degree of coupling means that if the HIL platform is changed, the test cases need to be rewritten, which consumes a lot of testers' time and energy and is inefficient. Therefore, how to improve the versatility of test cases in HIL testing using different HIL platforms is a problem that needs to be solved urgently.

[0046] The present application provides a solution, which calls a script conversion library corresponding to the HIL platform type according to the HIL platform type used for HIL testing, converts the same test case into a test script that can be run under the HIL platform, and adds a signal source address to the test script, thereby avoiding the need for testers to write separate test cases for different HIL platforms, and improving the versatility of test cases in HIL tests using different HIL platforms.

[0047] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, etc. The following takes an electronic device as an example to illustrate this embodiment and the following embodiments.

[0048] Based on this, the present application embodiment provides a test script generation method, referring to Figure 1 , Figure 1 This is a flowchart of the first embodiment of the test script generation method of the present application.

[0049] In this embodiment, the test script generation method includes steps S10 to S30:

[0050] Step S10, receiving a test case and a HIL platform type, and obtaining parameter variables in the test case;

[0051] It should be noted that the test case refers to the text data written by the user for HIL testing, the HIL platform type refers to the type of HIL platform configured by the user to indicate the type of HIL platform used for HIL testing, and the parameter variable refers to the field named based on a unified rule in the test case.

[0052] It is understandable that, since the test script running in the HIL platform needs to know the address of the test signal generated in the HIL platform, performing step S10 provides an effective data basis for obtaining the address of the test signal generated in the HIL platform.

[0053] In a feasible implementation manner, the parameter variable consists of a signal type, a read / write attribute, and a signal meaning, and step S10 may include steps S11-S12:

[0054] Step S11, receiving a test case and a HIL platform type, wherein the data format of the HIL platform type is a configuration file format;

[0055] It is understandable that in the traditional HIL testing process, after replacing the HIL platform used for HIL testing, the tester needs to reconfigure the test environment according to the replaced HIL platform, so step S11 is performed. After replacing the HIL platform used for HIL testing, it is only necessary to change the configuration items in the configuration file of the HIL platform type, thereby avoiding the operation of reconfiguring the complex test environment and improving the efficiency of HIL testing.

[0056] Step S12, obtaining the signal type of the parameter variable in the test case, the read-write property of the parameter variable and the signal meaning of the parameter variable.

[0057] It should be noted that the signal type defines the representation and transmission method of the parameter variable, the read / write attribute describes whether the parameter variable can be read or written, and the signal meaning describes the specific meaning and purpose of the parameter variable.

[0058] In a feasible implementation manner, the signal type includes at least any one of a hardware pin signal, a communication message signal, an A2L calibration signal, a model calculation signal and a test system environment variable, and the read-write attribute includes at least any one of a read attribute and a write attribute.

[0059] It should be noted that the hardware pin signal refers to the signal transmitted through the physical hardware interface, the communication message signal refers to the data packet transmitted through the network or bus, the A2L calibration signal refers to the signal used to calibrate and configure the electronic control unit ECU, the model calculation signal refers to the signal generated by the simulation model, the test system environment variable refers to the variable defined in the HIL test environment, the read attribute is used to describe the parameter variable can be read in the HIL test, and the write attribute is used to describe the parameter variable can be written in the HIL test.

[0060] Step S12 may include steps S121 to S123:

[0061] Step S121, obtaining any one of a hardware pin signal of the parameter variable in the test case, a communication message signal of the parameter variable, an A2L calibration signal of the parameter variable, a model calculation signal of the parameter variable, and a test system environment variable of the parameter variable;

[0062] It is understandable that since the test script needs to know the type of signal that the parameter variables used in the test need to generate when running in the HIL platform, step S121 is performed to obtain the signal type in the test case, thereby providing effective signal type information for generating the test script.

[0063] Step S122, obtaining any one of a read attribute of the parameter variable and a write attribute of the parameter variable in the test case;

[0064] It is understandable that since the test script needs to know the type of read and write operations required for the parameter variables used in the test when running in the HIL platform, step S122 is performed to provide effective read and write attribute information for generating the test script by obtaining the read and write attributes in the test case.

[0065] Step S123, obtaining the meaning of the signal in the test case.

[0066] It is understandable that since the test script needs to know the specific operations to be performed on the parameter variables used in the test when running in the HIL platform, step S123 is performed to obtain the signal meaning in the test case, thereby providing effective signal meaning information for generating the test script.

[0067] In this implementation, by obtaining the signal type, read-write properties and signal meaning of the parameter variables in the test case, an effective data basis is provided for generating the test script.

[0068] Step S20, calling a target conversion library in a preset script conversion library according to the HIL platform type, and converting the test case into a candidate test script through the target conversion library;

[0069] It should be noted that the preset script conversion library refers to a plurality of script conversion libraries that are used to convert test cases into test scripts that can be run on a variety of different HIL platforms; the target conversion library refers to a test script that is used to convert test cases into test scripts that can be run on the HIL platform specified by the received HIL platform type; and the candidate test script refers to a test script that does not contain a signal source address.

[0070] In a feasible implementation manner, the test script generation system at least includes a variable mapping dictionary, in which the mapping relationship between parameter variables and signal source addresses is recorded. Step S20 may include steps S21-S22:

[0071] Step S21, determining a target parameter variable in the variable mapping dictionary based on the HIL platform type and the parameter variable;

[0072] It should be noted that the variable mapping dictionary refers to a mapping table that records the mapping relationship between multiple parameter variables and multiple signal source addresses, and the target parameter variable refers to the data corresponding to the parameter variable in the variable mapping dictionary.

[0073] In a feasible implementation manner, the variable mapping dictionary also records the mapping relationship between parameter variables, HIL platform types and signal source addresses, and step S21 may include steps S211-S212:

[0074] Step S211, determining a candidate range of the variable mapping dictionary based on the HIL platform type;

[0075] It should be noted that the range to be selected refers to the data range in the variable mapping dictionary that is consistent with the received HIL platform type.

[0076] It can be understood that, since there are mapping relationships in the variable mapping dictionary where the same parameter variable corresponds to different HIL platform types, step S211 is performed to improve the accuracy of determining the target data corresponding to the parameter variable in the variable mapping dictionary by determining the candidate range of the variable mapping dictionary.

[0077] Step S212: determining the target parameter variable based on the parameter variable within the candidate range.

[0078] In this implementation, by determining the target parameter variable corresponding to the parameter variable in the test case within the candidate range, an effective way is provided for determining accurate mapping data.

[0079] Step S22, mapping the target parameter variable through the variable mapping dictionary to obtain the target signal source address corresponding to the target parameter variable, and using the target signal source address as the signal source address of the parameter variable.

[0080] It should be noted that the target signal source address refers to the data in the variable mapping dictionary that has a mapping relationship with the target parameter variable.

[0081] In this implementation manner, the signal source address required by the test script is obtained through the created variable mapping dictionary, thereby providing valid signal source address data for generating a complete test script.

[0082] Step S30, based on the HIL platform type and the parameter variable, determine the signal source address of the parameter variable, and write the signal source address into the candidate test script to obtain a test script, wherein the signal source address is the address of the test signal generated in the HIL platform.

[0083] It should be noted that the test script refers to a program that can be executed in the HIL platform.

[0084] In this embodiment, according to the type of HIL platform used for HIL testing, the script conversion library corresponding to the HIL platform type is called to convert the same test case into a test script that can be run under the HIL platform, and the signal source address is added to the test script, thereby avoiding the need for testers to write separate test cases for different HIL platforms, thereby improving the versatility of test cases in HIL testing using different HIL platforms.

[0085] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 , Figure 2 This is a flow chart of the second embodiment of the test script generation method of the present application. The step of converting the test case into a candidate test script by using the target conversion library in step S20 may include steps S201-S202:

[0086] Step S201, running the preset conversion code configured in the target conversion library, wherein the preset conversion code is developed based on the HIL platform type and is packaged in the form of a dynamic link library;

[0087] It is understandable that since the preset conversion code in the target conversion library needs to be highly flexible and reusable, step S201 is performed to improve the system performance of running the preset conversion code by running the preset conversion code encapsulated by the dynamic link library in the target conversion library.

[0088] Step S202: converting the test case into a candidate test script by using the preset conversion code.

[0089] In a feasible implementation, step S202 may include steps S01-S02:

[0090] Step S01, parsing the test case to obtain the test content of the test case, wherein the test content at least includes an input signal, an output signal and an execution action;

[0091] It should be noted that the test content refers to the content of the HIL test required as recorded in the test case, the input signal refers to the external input applied to the controller under test during the HIL test, the output signal refers to the response generated by the controller under test after receiving the input signal, and the execution action refers to the specific action that the HIL platform needs to perform during the HIL test.

[0092] Step S02: converting the test content into the candidate test script through the preset conversion code.

[0093] In this implementation, the test content is obtained by parsing the test case, and the test content is converted by converting the code to obtain the test script, which provides an effective way to convert the test case into a candidate test script.

[0094] In this embodiment, the test case is converted into a candidate test script through the conversion code in the script conversion library, so that the same test case can be converted into a test script that can be run in the specified HIL platform.

[0095] For example, to help understand the implementation process of the test script generation method obtained by combining this embodiment with the above-mentioned embodiment 1, please refer to Figure 3 , Figure 3 A scenario intention of a test script generation method is provided, specifically:

[0096] The received test case is input into the test script conversion unit in the script conversion tool chain. In the test script conversion unit, according to the platform configuration item, i.e., the received HIL platform type, the script conversion library corresponding to the platform configuration item is called to convert the test case to obtain a candidate test script. Based on the test case and the platform configuration item, the signal source path is determined through the variable mapping dictionary, and the signal source path is written into the candidate test script to obtain an automated test script, i.e., a test script.

[0097] Further, please refer to Table 1 below:

[0098]

[0099] Table 1

[0100] The variable mapping dictionary in Table 1 consists of three parts, namely, the variable name, i.e., the parameter variable, the Type field, i.e., the HIL platform type, and the model book path, i.e., the signal source path. The variable name in the variable mapping dictionary consists of three fields, including the signal type, the read / write attributes, and the abbreviation of the signal meaning. The signal types include hardware pin signals (HW), communication message signals (COMM), A2L calibration signals (CALI), model calculation signals (MDL), and test system environment variables (ENV). The read / write attributes include read attributes (RD) and write attributes (WT). The Type field is the abbreviation of each HIL platform. For example, the Type field corresponding to NI's VeriStand is (VS). Take serial number 1 as an example: variable number 1 in the variable mapping dictionary is HWWT_IDL_CDL_Lock_SW_WU, indicating the hardware output interface for controlling the central locking switch. The model tree path 1 corresponding to variable number 1 under the Type field (VS) in the variable mapping dictionary is Targets / Controller / Custom Devices / TB2810 / Output / DigitalOut / D05. This path 1 indicates that the parameter variable is a switch-type digital input signal for the controller to be tested, and the signal is simulated and sent by channel 5 of the digital output board TB2810 inside the HIL platform.

[0101] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the test script generation method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.
