Description

Technical Field

[0001] The present application relates to the field of data processing technology, and in particular to a method for generating a UDS diagnostic service test case and related equipment. Background Art

[0002] Vehicle diagnostics is the process of detecting and locating vehicle faults. It is a critical software function for ensuring vehicle safety and performance. The most commonly used vehicle diagnostic protocol is Unified Diagnostic Services (UDS), an application-layer protocol based on the ISO 14229 standard. It uses a "question-and-answer" model, where the diagnostic tool sends a diagnostic service request to the vehicle's Electronic Control Unit (ECU). The ECU responds accordingly and returns the response to the diagnostic tool, allowing for quick and accurate identification of vehicle faults and their causes, providing a reliable basis for development and maintenance.

[0003] Diagnostic services are both the most important and complex functions in vehicle software development. Currently, UDS diagnostic service test cases are manually written based on the diagnostic service support information provided in the diagnostic questionnaire and combined with test cases from previous projects. Due to the large number of diagnostic service service identifiers (SIDs), the testing workload is high, and the diagnostic service requirements vary from project to project. This often requires testers to spend a significant amount of time writing diagnostic service test cases, making it difficult to ensure adequate test coverage. Summary of the Invention

[0031] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0032] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically separate entities. That is, these functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0033] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, while others may be combined or partially combined. Therefore, the actual execution order may vary depending on the actual situation.

[0034] In this application, "plurality" refers to two or more. "And / or" describes the relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0035] In order to solve the problem that the existing diagnostic service test case generation process is complicated and cumbersome, and the lack of efficiency leads to insufficient coverage, the embodiments of the present application propose a UDS diagnostic service test case generation method and device, electronic device, and computer-readable storage medium, which mainly involve the UDS diagnostic service test case generation technology included in the data processing technology. These embodiments will be described in detail below.

[0036] First see Figure 1 , Figure 1 This is a flowchart of a method for generating a UDS diagnostic service test case, as illustrated by an exemplary embodiment of the present application. This method can be specifically executed by a server, which can be a standalone server or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDNs), and big data and artificial intelligence platforms, without limitation.

[0037] like Figure 1 As shown, in an exemplary embodiment, the method for generating a UDS diagnostic service test case may include steps S101 to S105, which are described in detail as follows:

[0038] Step S101: Acquire project information of a target diagnostic project.

[0039] Step S102: determining a target diagnosis service type of a target diagnosis item.

[0040] Step S103 : Selecting a configuration table that matches the target diagnostic service type from the preset configuration tables as an initial configuration table.

[0041] Step S104: obtaining a target configuration table corresponding to the target diagnosis item based on the item information and the initial configuration table.

[0042] Step S105 : obtaining a target diagnosis service test case that matches the target diagnosis project based on the target diagnosis service type, the target configuration table, and the preset test case template file.

[0043] As can be seen from the above, in the method provided in this embodiment, by obtaining the project information of the target diagnostic project; determining the target diagnostic service type of the target diagnostic project; selecting a configuration table that matches the target diagnostic service type from the preset configuration table as the initial configuration table; based on the project information and the initial configuration table, obtaining the target configuration table corresponding to the target diagnostic project; based on the target diagnostic service type, the target configuration table and the preset test case template file, obtaining the target diagnostic service test case that matches the target diagnostic project. In this way, the application itself realizes the automatic generation of diagnostic service test cases, saving the time of manually writing test cases. It only needs to obtain the project information of the target diagnostic project to generate a diagnostic service test case that matches the current project, which greatly improves the test efficiency while ensuring the uniformity of the diagnostic service test and the coverage of the test cases.

[0044] It should also be noted that the project information of the target diagnostic project in this application can be generated and transmitted by relevant personnel, or it can be pulled through big data using the Internet, and there is no restriction here.

[0045] In an exemplary embodiment of the present application, the specific steps of determining the target diagnosis service type of the target diagnosis item may include:

[0046] Get the service identifier of the diagnostic service of the target diagnostic project;

[0047] The corresponding relationship between the preset service identifier and the diagnostic service type is obtained, and the target diagnostic service type of the target diagnostic item is determined based on the corresponding relationship and the service identifier. The target diagnostic service type is a basic service, a fixed service, or a variable service.

[0048] In this embodiment, the target diagnostic service type is divided into basic services, fixed services or variable services using the service identifier of the diagnostic service of the target diagnostic project. Basic services include diagnostic services represented by service identifiers such as 0x10 services and 0x27 services. These services are the prerequisites for the use of other services in UDS, and the basic services of different projects generally do not change much. Fixed services include diagnostic services represented by service identifiers such as 0x11 services, 0x28 services, 0x3E services, 0x85 services, and 0x14 services. This type of service is a commonly used service in UDS, and the fixed services of different projects generally do not change much. The main difference between fixed services and basic services is that the use of fixed services needs to rely on basic services. Variable services include diagnostic services represented by service identifiers such as 0x19 services, 0x22 services, 0x2E services, and 0x31 services. The variable service functions of different projects vary greatly.

[0049] In this way, through the above embodiments, the present application enables the UDS diagnostic service test case generation method provided by the present application to be applied to the test case generation of various target diagnostic projects, thereby improving the coverage of the generated test cases.

[0050] In an exemplary embodiment of the present application, the target diagnostic service type is a basic service, a fixed service, or a variable service. Therefore, the specific steps of selecting a configuration table that matches the target diagnostic service type from the preset configuration table as the initial configuration table may include:

[0051] When the target diagnostic service type is a basic service, a matching basic service configuration table is selected from the preset configuration table as the initial configuration table;

[0052] When the target diagnostic service type is a fixed service, a matching fixed service configuration table is selected from the preset configuration table as the initial configuration table;

[0053] When the target diagnosis service type is a variable service, multiple data identifiers included in the target diagnosis item are obtained;

[0054] A variable service configuration table that matches the target diagnostic service type and a data identifier configuration table that matches the data identifier are selected from the preset configuration table as the initial configuration table.

[0055] In this embodiment, corresponding initial configuration tables are preset for different target diagnostic service types, which are used to form target configuration tables with contents corresponding to their types. Figures 2 to 4, which are the initial configuration tables corresponding to basic services, fixed services and variable services respectively. Figure 2 is a schematic diagram of a basic service configuration table in an exemplary embodiment of the present application, Figure 3 is a schematic diagram of a fixed service configuration table in an exemplary embodiment of the present application. Figure 4 It is a schematic diagram of a variable service configuration table in an exemplary embodiment of the present application.

[0056] Different initial configuration tables list the information that needs to be entered from the project information for this target diagnostic service type, such as Figure 3 As shown, the fixed services need to clarify the following:

[0057] (1) Whether functional addressing or physical addressing is supported. In vehicle diagnostic services, functional addressing and physical addressing are two different addressing methods. Functional addressing broadcasts diagnostic service requests and waits for responses from all ECUs on the bus that support functional addressing. Physical addressing, on the other hand, sends diagnostic requests to a specific ECU and waits for a response from the specified ECU.

[0058] (2) Required security unlocking level. Some diagnostic services of the ECU may contain important information or sensitive operations. When requesting these diagnostic services, permission authentication is required. Only when the corresponding security level is correctly unlocked can further operations be performed. Otherwise, access is impossible.

[0059] (3) Whether the positive response suppression bit is supported. The positive response suppression bit allows the ECU to suppress the positive response to the diagnostic service request in certain circumstances. It can reduce the bus load or unnecessary communication as needed, and also provides a mechanism to optimize diagnostic communication.

[0060] (4) Supported session types. The UDS protocol defines three session modes: default session, programming session, and extended session. Different session modes can be switched between each other, but only one diagnostic session is always active. The ECU is usually in the default session, but many services need to be switched to the extended session mode or programming session mode to be executed.

[0061] This application targets variable services that include multiple data identifiers. In order to generate accurate target diagnostic service test cases, the content that needs to be configured for the variable service is further divided into data identifiers according to the preset data identifier types, and a data identifier configuration table corresponding to the data identifiers is configured. Figure 5 , Figure 5 FIG. 1 is a schematic diagram of a data identifier configuration table in an exemplary embodiment of the present application. Figure 5As shown, the preset data identifier types include the DTC (Diagnostic Trouble Code) corresponding to the 0x19 service, the DID (Data Identifier) ​​corresponding to the 0x22 and 0x2E services, and the RID (Routine Identifier) ​​corresponding to the 0x31 service. The data identifier configuration table includes the DTC configuration table, the DID configuration table, and the RID configuration table. A DTC is a code generated by the vehicle's electronic control unit (ECU) when it detects a system fault. It uniquely identifies a specific fault condition in the vehicle, helping maintenance personnel quickly locate and troubleshoot the problem. A DID is a number used to identify a specific data object in the UDS protocol. The ECU stores various types of data. To ensure accurate access and transmission of this data, each data object is assigned a unique DID. An RID identifies a specific diagnostic routine in the UDS. A diagnostic routine is a series of predefined steps used to perform a specific diagnostic task, such as activating a sensor for self-testing or performing a functional test.

[0062] In this way, through the above embodiments, the present application presets corresponding initial configuration tables for different target diagnostic service types, which are used to form target configuration tables with contents corresponding to their types, so as to improve the accuracy of subsequently generated test cases.

[0063] In an exemplary embodiment of the present application, the target diagnostic service type is a basic service, a fixed service, or a variable service. Therefore, based on the target diagnostic service type, the target configuration table, and the preset test case template file, the specific steps of obtaining a target diagnostic service test case that matches the target diagnostic project may include:

[0064] When the target diagnostic service type is basic service or fixed service, read the configuration result of the target configuration table;

[0065] Obtaining the template content that matches the configuration result in the preset test case template file, and obtaining the target diagnosis service test case that matches the target diagnosis project based on the template content;

[0066] When the target diagnosis service type is a variable service, the configuration result of the target configuration table is read, and a target diagnosis service test case matching the target diagnosis item is generated based on the configuration result.

[0067] In this embodiment, by reading the configuration content in the target configuration table, copying the corresponding test case in the test case template file or directly generating the target diagnostic service test case according to the configuration result, the automatic generation of test case files for different projects is achieved. Preferably, for the test cases of basic services and fixed services, the corresponding test cases can be copied in the test case template file according to the configuration content supported in the target configuration table. For the test cases of variable services, the DTC configuration table, DID configuration table and RID configuration table corresponding to the variable service are read in the target configuration table to generate the corresponding target diagnostic service test case.

[0068] In another exemplary embodiment, when the target diagnostic service type is a basic service or a fixed service, the specific steps of obtaining a target diagnostic service test case that matches the target diagnostic item may include:

[0069] Obtaining a mapping relationship between a test case description and test case steps represented by a test case template in a preset test case template file;

[0070] Based on the target test case description and the mapping relationship of the configuration result, a test case step matching the target test case description is obtained as the target test case step;

[0071] Based on the target test case description and the target test case steps, a template content matching the configuration result is obtained, and the template content is used as a target diagnosis service test case matching the target diagnosis project.

[0072] In this embodiment, the test case template file is a .xlsx type file that stores a complete test case as a test case template for basic services and fixed service functions. Taking the sub-service 0x03 of the 0x11 service as an example, part of the content in its test case template file is shown in Table 1.

[0073] Table 1, part of the test case template file for 0x11 service 0x03 subservice:

[0074]

[0075]

[0076] The preset test case template file stores a test case template, which represents the mapping relationship between the test case description and the test case steps. This embodiment obtains the test case steps that match the target test case description based on the target test case description and the mapping relationship of the configuration results as the target test case steps; based on the target test case description and the target test case steps, the template content that matches the configuration results is obtained, and the template content is used as the target diagnostic service test case that matches the target diagnostic item.

[0077] In this way, through the above embodiments, the present application directly obtains the test cases that match the basic services and fixed services that do not change, and uses them as target diagnostic service test cases, thereby improving data processing efficiency while ensuring the accuracy of the results.

[0078] In another exemplary embodiment, when the target diagnostic service type is a variable service, the target configuration table includes a variable service configuration table and a data identifier configuration table; therefore, the specific steps of reading the configuration result of the target configuration table and generating a target diagnostic service test case matching the target diagnostic item based on the configuration result may include:

[0079] Reading a variable service configuration table and a data identifier configuration table to obtain a configuration result, wherein the data identifier configuration table is at least one of a DTC configuration table, a DID configuration table, and a RID configuration table;

[0080] Generate target diagnosis service test cases that match the target diagnosis project based on the configuration results.

[0081] In another exemplary embodiment, the specific steps of generating a target diagnosis service test case matching the target diagnosis project based on the configuration result may include:

[0082] Obtain the conversion relationship between the preset configuration result and the script variable, and convert the configuration result into the target script variable based on the conversion relationship;

[0083] Generate a field set corresponding to the configuration result based on the target script variable through conditional judgment;

[0084] The field collection is spliced ​​to obtain a target diagnostic service test case that matches the target diagnostic project.

[0085] In this embodiment, for target diagnostic items of variable services, a target diagnostic service test case matching the target diagnostic item is generated based on the configuration results of the variable service configuration table and the data identifier configuration table. Taking the target diagnostic item with a 0x2E service and a corresponding data identifier of DID as an example, the 0x2E service configuration is read from the variable service configuration table, the DID configuration is read from the DID configuration table, and the read results are converted into target script variables. The corresponding relationships are shown in Tables 2 and 3.

[0090]

[0091] According to the results read from the variable service configuration table and the DID configuration table, the corresponding field set is generated through conditional judgment. The meaning of each field is shown in Table 4.

[0094]

[0095] All field sets are spliced ​​together through a for loop to generate the Test Case Description and Test Step. The correspondence between some items of the test case and the code in the script is shown in Table 5.
