[0026] Embodiment 1

[0027] Figure 1 A flowchart of a test case generation method is provided for the first embodiment of the present invention. This embodiment is applicable to the case of generating test cases for a hardware-in-the-loop test system according to test requirements. The method can be executed by a test case generation device, which can be implemented in the form of hardware and / or software, and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0028] S110: Determine a test signal variable list of the domain controller, and generate a variable mapping file according to the test signal variable list through a hardware-in-the-loop test system.

[0029] The vehicle's domain controller is an integrated controller used to manage and control multiple embedded electronic control units in the vehicle's electronic system. The domain controller can serve as the center of the vehicle's electronic system, and by processing and distributing data, it can coordinate and communicate between the various electronic control units to achieve comprehensive control and optimization of the vehicle system.

[0030] The test signal variable list includes an observation signal variable list and a simulation signal variable list, which can be determined based on the test requirements of the domain controller. When determining the test signal variable list based on the test requirements of the domain controller, the source of the observation signal variable list is mainly the signal variables corresponding to the control system flash file of the domain controller, and the source of the simulation signal variable list is mainly the simulation input signal variables and simulation output signal variables in the hardware-in-the-loop test system.

[0031] Among them, the Hardware in the Loop (HIL) test system can simulate the operating state of the controlled object by running a simulation model on a real-time processor, and connect with the electronic control unit under test through the I / O interface to achieve comprehensive and systematic testing of the electronic control unit, reduce development time and cost, and improve test efficiency and safety.

[0032] The variable mapping file includes a list of test signal variables, mapping addresses that can be identified by the HIL test system, and the mapping relationship between the two. The variable mapping file can be used as a signal variable definition and mapping address library file when generating test cases.

[0033] In an embodiment of the present invention, after determining the test signal variable list, that is, the observation signal variable list and the simulation signal variable list, based on the domain control controller test requirements, a variable mapping file can be generated through the hardware-in-the-loop test system according to the observation signal variable list and the simulation signal variable list, so as to ensure that the generated test cases can be directly and successfully executed by the HIL test system through the variable mapping file during the test case generation process.

[0034] Optionally, a variable mapping file is generated according to the test signal variable list by a hardware-in-the-loop test system, including: importing the test signal variables in the test signal variable list into the hardware-in-the-loop test system; linking the test signal variables to a mapping address recognizable by the hardware-in-the-loop test system, and generating a variable mapping file.

[0035] In an embodiment of the present invention, after determining the test signal variable list of the domain controller, the test signal variables in the test signal variable list can be imported into the HIL test system according to the HIL use case operating environment, and the test signal variables can be linked to the mapping address that the HIL test system can recognize, and a variable mapping file is generated. It should be noted that the test signal variables involved in the test case should all exist in the variable mapping file to avoid test case generation failure. Optionally, in order to ensure test coverage and speed up test preparation time, all analog bus transceiver signals in the HIL test system can be added to the variable mapping file for the communication interface test signal variables in the test signal variables. If the names of the analog bus transceiver signals are repeated, they can be identified by adding suffixes and the like.

[0036] S120 , generating a target test case table according to the test signal variable list, a predetermined test case template, and a test case generation rule.

[0037] Among them, the predetermined test case templates include the initialization worksheet (Init), the function worksheet (Fun), and the end worksheet (CleanUp). The initial worksheet corresponds to the test preparation part of the HIL test, such as powering on the system, enabling current output, connecting the configuration project, etc. The function worksheet corresponds to the test execution part of the HIL test, which can be a large worksheet or divided into multiple worksheets according to the signal group. The end worksheet corresponds to the test preparation part of the HIL test, such as disconnecting the configuration project connection, powering off the system, etc.

[0038] Among them, the test case generation rules are used to define the structure, name and type of the test case to be generated. Exemplarily, according to the test case generation rules, the structure of the test case to be generated can be determined as an initial part, a test step part and an end part. Accordingly, the content of the initial part comes from the initial worksheet, the content of the test step part comes from the function worksheet, and the content of the end part comes from the end worksheet.

[0039] In an embodiment of the present invention, a predetermined test case template can be filled at the signal variable level according to the test signal variable list, and at the same time, according to the test case generation rule, specific parameters in the test case template are set to obtain a target test case table for generating a target test case. By filling the test case template at the signal variable level, it is convenient to add and delete signal variables in the test case template according to test requirements, and it has strong readability.

[0040] S130: Generate a target test case according to the target test case table and the variable mapping file.

[0041] In the embodiment of the present invention, the target test case table can be automatically converted into a target test case executable by the HIL test system through a script and a variable mapping file, so as to improve the test case generation efficiency and shorten the test case preparation time.

[0042] Optionally, a target test case is generated according to the target test case table and the variable mapping file, including: traversing all signal variables in the target test case table to determine the mapping address corresponding to the signal variable in the variable mapping file; determining the test case execution part corresponding to the signal variable from the mapping address according to the execution type of the signal variable, and adding the test case execution part to the target test case table; generating an automatic test sequence file according to the target test case table after adding the test case execution part, and using the test case in the automatic test sequence file as the target test case.

[0043] In an embodiment of the present invention, a variable mapping file can be exported from a HIL test system, and the signal variables added in the target test case table can be traversed by a script to determine the mapping address corresponding to the signal variable in the variable mapping file. Afterwards, according to the execution type of the signal variable, the test case execution part that can be executed by the HIL test system corresponding to the signal variable is determined from the mapping address, and the test case execution part is added to the target test case table. Finally, an automatic test sequence file is generated according to the target test case table after adding the test case execution part, and the test case in the automatic test sequence file is used as the target test case. Through the variable mapping file, the target test case table can be converted into a target test case that can be successfully executed by the HIL test system, thereby improving the generation efficiency of the test case and shortening the test case preparation time.

[0044] Optionally, after obtaining the target test case, the target test case may be imported into the HIL test system for execution, and the predetermined test case template may be optimized according to the test result to improve the quality of the generated test case.

[0045] The technical solution of the embodiment of the present invention determines the test signal variable list of the domain control controller, and generates a variable mapping file according to the test signal variable list through a hardware-in-the-loop test system; generates a target test case table according to the test signal variable list, a predetermined test case template and a test case generation rule; generates a target test case according to the target test case table and the variable mapping file. The technical solution of the embodiment of the present invention fills the predetermined test case template at the signal variable level according to the determined test signal variable list, generates a target test case table that conforms to the test case generation rule, and realizes the conversion from the target test case table to the target test case through the variable mapping file, which can improve the test case generation efficiency and shorten the test case preparation time.

[0046] Embodiment 2

[0047] Figure 2 This is a flow chart of a test case generation method provided by the second embodiment of the present invention. The embodiment of the present invention is optimized based on the above embodiment. For solutions not described in detail in the embodiment of the present invention, please refer to the above embodiment. Figure 2 As shown, the method includes:

[0048] S210: Determine a test signal variable list of the domain controller, and generate a variable mapping file according to the test signal variable list through a hardware-in-the-loop test system.

[0049] S220: Import the test signal variable list into a predetermined test case template to generate a first test case table.

[0050] Among them, the predetermined test case template includes the initialization worksheet (Init), the function worksheet (Fun) and the end worksheet (CleanUp). The initial worksheet corresponds to the test preparation part of the HIL test, such as system power-on, enabling current output, connection configuration engineering, etc., as shown in Table 1 below:

[0051] Table 1 Initial worksheet

[0052]

[0053] The functional worksheet corresponds to the test execution part of the HIL test, as shown in Table 2 below:

[0054] Table 2 Functional worksheet

[0055]

[0056] The end worksheet corresponds to the test preparation part of the HIL test, such as disconnecting the configuration project connection and powering off the system, as shown in Table 3 below:

[0057] Table 3 End of worksheet

[0058]

[0059] In the embodiment of the present invention, the test signal variable list is imported into the predetermined test case template, that is, the predetermined test case template is filled at the signal variable level according to the test signal variable list, thereby generating a first test case table.

[0060] Optionally, the test signal variable list is imported into a predetermined test case template to generate a first test case form, including: filling in the initialization worksheet, the function worksheet and the end worksheet according to the test signal variable list, and correspondingly generating a test preparation worksheet, a test execution worksheet and a test end worksheet; generating the first test case form according to the test preparation worksheet, the test execution worksheet and the test end worksheet.

[0061] In an embodiment of the present invention, the initialization worksheet, the function worksheet and the end worksheet can be filled in respectively according to the test signal variable list, and a test preparation worksheet, a test execution worksheet and a test end worksheet are generated accordingly. Exemplarily, according to the test signal variable list, the signal variables, program names, execution types, values, waiting times, etc. in the initial worksheet can be filled in, the signal groups, signal variables, execution types, values, waiting times, etc. in the function worksheet can be filled in, and the signal variables, program names, execution types, values, waiting times, etc. in the end worksheet can be filled in, and a test preparation worksheet, a test execution worksheet and a test end worksheet can be generated accordingly. Among them, when filling in the execution type, for the analog signal variables in the test signal variables, the execution type of the analog input signal variables in the analog signal variables can be set to "write", and the execution type of the analog input signal variables can be set to "read", and for the observation signal variables in the test signal variables, the execution type of the calibrable signal variables in the observation signal variables can be set to "write", and the execution type of the observable part signal can be set to "read". Afterwards, a first test case table is generated according to the test preparation worksheet, the test execution worksheet and the test end worksheet.

[0062] Optionally, in the process of importing the test signal variable list into a predetermined test case template to generate a first test case table, it also includes: when filling in numerical items according to the test signal variable list, if the number of numerical items to be filled is greater than the number of columns corresponding to the numerical row, then starting another row under the numerical row to continue filling in the unfilled numerical items.

[0063] In the embodiment of the present invention, the numerical items can be regarded as an independent table. When filling the numerical items according to the test signal variable list, if the number of numerical items to be filled is greater than the number of columns corresponding to the numerical row, another row under the numerical row can be started to continue to fill the unfilled numerical items. Exemplarily, the numerical items in Tables 1-3 above can be regarded as an independent table, as shown in Table 4 below, where the number of columns corresponding to the numerical row contains 16 columns, namely Value0-Value15. If the number of numerical items to be filled is greater than 16, another row under the numerical row can be started to continue to fill the unfilled numerical items.

[0064] Table 4 Numerical items table

[0065]

[0066] S230: Determine the name and type of the test case to be generated according to the first test case table and the test case generation rule, and generate a second test case table based on the name and type.

[0067] In an embodiment of the present invention, the name and type of the test case to be generated can be determined according to the test case generation rules and the filled test case template, that is, the first test case table, and the second test case table can be generated based on the name and type.

[0068] Optionally, according to the first test case table and test case generation rules, the name and type of the test case to be generated are determined, including: determining the test execution worksheet in the first test case table, and determining the signal group in the test execution worksheet; determining the name and type of the test case to be generated corresponding to the signal group according to the test case generation rules.

[0069] Among them, the signal group is a collection of signal variables of a certain type. In the embodiment of the present invention, one signal group can correspond to one test case, or multiple signal groups can correspond to one test case. The specific number can be determined based on actual needs and test case generation rules.

[0070] In the example of the present invention, it is necessary to first determine the test execution worksheet in the first test case table, then determine the signal group in the test execution worksheet, and determine the name and type of the test case to be generated corresponding to the signal group according to the test case generation rule. Exemplarily, the name (TestCaseName) of the test case to be generated corresponding to the signal group can be determined according to the controller name, signal group name and test type corresponding to the signal group in the test execution worksheet. The automatic generation column (Generate) of the signal group can be set to determine the type of the test case to be generated, such as by setting the automatic generation column of the signal group row to Y, the test case generation of all signal variables under the signal group is realized; by setting the automatic generation column of the signal group row to N, the test case of all signal variables under the signal group is realized not to be generated; by setting the automatic generation column of the first signal group row in each test execution worksheet to Y, the other signal group rows remain empty, the signal variables of the entire test execution worksheet can be generated to a test case, which is called a fast test case, and is marked by fast. In addition, the generation of the use case corresponding to the signal variable in the signal group can be canceled by clearing the execution type row content corresponding to a certain signal variable row in the signal group. Afterwards, a second test case table may be generated based on the name and type. For example, the following Table 5 shows a second test case table.

[0071] Table 5 Second test case table

[0072]

[0073] S240: Use the first test case table and the second test case table as target test case tables.

[0074] In the embodiment of the present invention, after the first test case table and the second test case table are generated, the first test case table and the second test case table may be used as target test case tables for generating target test cases.

[0075] S250: Generate a target test case according to the target test case table and the variable mapping file.

[0076] The technical solution of the embodiment of the present invention determines the test signal variable list of the domain control controller, and generates a variable mapping file according to the test signal variable list through a hardware-in-the-loop test system; imports the test signal variable list into a predetermined test case template to generate a first test case table; determines the name and type of the test case to be generated according to the first test case table and the test case generation rule, and generates a second test case table based on the name and type; uses the first test case table and the second test case table as the target test case table; generates a target test case according to the target test case table and the variable mapping file. The technical solution of the embodiment of the present invention fills the predetermined test case template at the signal variable level according to the determined test signal variable list, generates a target test case table that meets the test case generation rules, and realizes the conversion of the target test case table to the target test case through the variable mapping file, which can improve the test case generation efficiency and shorten the test case preparation time.
