[0025] The present disclosure provides an automatic diagnosis test method, device, electronic device, storage medium and program product, which can improve code reuse rate, reduce maintenance cost and improve test efficiency.

[0026] Figure 1 It is a flowchart of the automatic diagnostic test method provided by the embodiment of the present disclosure. This specification provides method operation steps such as the embodiment or flowchart, but more or fewer operation steps may be included based on conventional or non-creative labor. The order of steps listed in the embodiment is only one way of executing the order of many steps and does not represent the only execution order. When the actual system or server product is executed, it can be executed in the order of the method shown in the embodiment or the accompanying drawings or in parallel (for example, in a parallel processor or multi-threaded processing environment).

[0027] S101: Reading table data for storing at least one group of test cases, each group of test cases including a plurality of diagnostic test command information, wherein the diagnostic test command information includes an addressing mode and a test step.

[0028] The table data stores at least one group of test cases, and each group of test cases contains multiple diagnostic test command information, and the diagnostic test command information includes at least an addressing mode and a test step. Among them, the test steps include two types: diagnostic commands and specific test actions, and for the case where the test step is a diagnostic command, an addressing mode for UDS is set. In the case where the test step is a specific test action, there is no need to set the addressing mode. In addition, the diagnostic test command information may also include an expected result for comparison with the reply message of the diagnostic command to automatically determine the diagnostic test result. In the case where the test step is a specific test action, there is no need to set the expected result.

[0029] Each group of test cases may be provided with a test case ID, and the test case ID may correspond one-to-one to each vehicle manufacturer, for example, so that the test case specific to the corresponding vehicle manufacturer may be read through the test case ID.

[0030] In addition, the table data includes at least one of EXCEL table data, database table data and WPS table data.

[0031] Figure 2 This is an example of the table data provided by the embodiment of the present disclosure. This embodiment uses an EXCEL file to carry test case data, and the EXCEL file stores test cases that have been pre-edited and debugged. This example includes a group of test cases E, and the test case ID of this group of test cases is the OEM_ID recorded in the first column and the first row. The second column of the table is the addressing mode, the third column is the test steps, and the fourth column is the expected result.

[0032] like Figure 2 As shown, the test case ID can be set only in the first cell of a group of test cases, thereby indicating that the group of test cases is the test case of a corresponding vehicle manufacturer.

[0033] Figure 2 In the third column of the table data example, the test steps in the second and third rows represent diagnostic commands, which are 22 01 and 22 02 respectively. There will be a diagnostic command reply after the diagnostic command is sent. Therefore, the expected result of the test is also preset in the fourth column of expected result. Figure 2 The third column and the fourth to eighth rows of the table data example represent specific test actions. When the test steps are specific test actions, the addressing mode and expected results may not be set.

[0034] S102: Parse a group of test cases in the table data and save them into an initialized preset array.

[0035] In the case where test case IDs are set for various test cases in the table data, when a group of test cases in the table data is parsed, a group of test cases can be selected based on the test column ID. For example, when performing diagnostic tests automatically using software, the test case ID can be specified in advance, so that in step S102, only a group of test cases whose test case ID is the specified test case ID is selected. After parsing the selected group of test cases, they are saved to a preset array, which is set according to the format of the table data, and can save multiple diagnostic test command information of a group of test cases line by line, and ensure that any group of test cases in the table data can be accommodated. Of course, before each test case is saved, the preset array is initialized.

[0036] S103: Utilizing the test system and based on a preset array storing a group of test cases, sequentially execute multiple diagnostic test command information of the group of test cases.

[0037] The multiple pieces of diagnostic test command information of a group of test cases are stored line by line in a preset array, so the test system can execute the multiple pieces of diagnostic test command information of the group of test cases in sequence based on the preset array.

[0038] As mentioned above, the test steps include two types: diagnostic commands and specific test actions. If the test step in a diagnostic test command message is a specific test action, the corresponding command is triggered to execute the specific test action. For example, if the test step in a diagnostic test command message is "Power Off", the power-off action is executed. If the test step in a diagnostic test command message is a diagnostic command, it further includes the following sub-steps:

[0039] (1) Generate a diagnostic command message based on the addressing mode and test steps in the diagnostic test command information, and send the diagnostic command message.

[0040] (2) Receive the diagnostic command reply message.

[0041] (3) Parsing the diagnostic command reply message to determine whether the diagnostic command reply is consistent with the expected result in the diagnostic test command information. Parsing the diagnostic command reply message may be to extract the portion of the diagnostic command reply message related to the reply result, parse it into the format shown by the expected result in the diagnostic test command information, and then compare it with the expected result to determine whether the two are consistent.

[0042] (4) If they are consistent, the result of passing the test will be written into the test report; if they are inconsistent, the result of failing the test will be written into the test report.

[0043] In the automatic diagnostic test method of this embodiment, a preset parameter can be set to determine whether the diagnostic test is UDS on CAN or UDS on DoIP. Among them, UDS on CAN refers to UDS based on the controller area network bus (CAN, Controller Area Network), and UDS on DoIP refers to UDS based on Ethernet. The automatic diagnostic test method of this embodiment further includes a step of setting a preset parameter for determining whether the diagnostic test is UDS on CAN or UDS on DoIP, which step can be performed before step S103.

[0044] When the preset parameters are set, in sub-step (1) of step S103, different frame transmission protocols are applied according to the preset parameters, and when the preset parameters indicate that the diagnostic test is UDS on DoIP, an Ethernet header needs to be added to the diagnostic command message.

[0045] In addition, when the preset parameters are set, in sub-step (3) of step S103, when the preset parameters indicate that the diagnostic test is UDS on DoIP, the Ethernet header is first removed and then parsed.

[0046] According to the present disclosure, only the table data needs to be maintained, and the rest of the code can be fixed without modification, thereby increasing the code reuse rate and reducing maintenance costs. In addition, by having a machine determine whether the diagnostic command reply is consistent with the expected result, it can reduce the misjudgment of manual judgment and improve the accuracy, and undoubtedly improve the test efficiency.
