[0032] Example 1

[0033] The method embodiment provided in the first embodiment of the present application can be executed in an emulator, a computer, a test terminal or a similar processing device. Taking running on a computer as an example, Figure 1 This is a hardware structure diagram of a computer according to an embodiment of the present invention. Figure 1 As shown, the server may include one or more ( Figure 1 Only one is shown) a processor 102 (the processor 102 may include but is not limited to a microprocessor MCU or a programmable logic device FPGA and other processing devices) and a memory 104 for storing data.

The processor 102 executes various functional applications and data processing by running the server program stored in the memory 104, that is, implementing the above-mentioned method.

[0035] The transmission device 106 is used to receive or send data via a network.

In another embodiment, the transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0036] In this embodiment, a simulation test method based on DDS is provided. Figure 2 FIG. 1 is a flow chart of a DDS-based simulation test method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0037] Step S202: monitoring the source DDS message sent by the service module to be tested;

[0038] The solution of this embodiment can be applied in a scenario of testing and simulating a service module. The execution subject of this embodiment is a simulation module that performs simulation testing.

[0039] Optionally, the business module may be various functional modules of the car, such as an air-conditioning module, a voice module, and other control modules.

[0040] Step S204: Read a preconfigured relationship configuration table, wherein the relationship configuration table is used to store a first mapping relationship between the message structure of the source DDS message and the response DDS message, and a second mapping relationship between the message structure and test data, wherein the message structure is used to represent the message type of the response DDS message to be simulated, and the test data is used to represent the message content of the response DDS message to be simulated;

[0041] For example, let's say the business module to be tested is A, and the simulation module is B. Because A's business needs to be tested, the orchestration solution configures B's behavior and test data, and the entire process is based on DDS message interaction. The test process requires two considerations: 1. After module A sends a DDS message, what DDS message should module B respond to after receiving it according to the normal business process? 2. The data content of module B's response DDS message. These two points are implemented through the first and second mapping relationships in the relationship configuration table, respectively, and are explained here:

[0042] Assume that during the entire business process, after A sends Message 1 to B, it is designed to receive Message 2 (or even Message 3, Message 4, etc.) from B in order for A's module to continue normal business execution. For example, if A requests B to adjust the air conditioner temperature to 26° (currently 30°), B must respond that the temperature has been adjusted to 26° before A can confirm that the temperature has been adjusted to 26°. If A does not receive this response from B, it will not make subsequent temperature changes (and will still believe that the current temperature is 30°).

[0043] Taking the air conditioner temperature example above, when module B responds to A's air conditioner temperature, let's assume that module B can only set the lowest setting to 27°. Module B assumes that any temperature setting request from A below the minimum of 27° will be set to 27°. If A requests 26°, module B's response message is 27°. If A requests 28°, module B's DDS response message is 28°. Alternatively, module B may be limited and always respond with other data. Therefore, the simulation module B not only responds to A's messages, but the orchestration also supports custom response data values.

[0044] Here, the first mapping relationship in the relationship configuration table shows the relationship between the source DDS message sent by module A and the DDS message type responded by simulation module B. For example, A's message a corresponds to B's message b, and A's message c corresponds to B's messages d and e. That is, when B receives a, it needs to respond to b; when B receives c, it needs to respond to d and e. The second mapping relationship is illustrated as follows: the relationship between the DDS message data sent by A and the test data published in the subsequent response DDS message sent by B. This is the test data generation method used by B in responding to A's message, such as fixed value, static value, dynamic value, etc.

[0045] Step S206, simulating and arranging a response DDS message of the source DDS message based on the relationship configuration table;

[0046] Step S208: Send the response DDS message to the service module.

[0047] The purpose is to test whether the business of the module under test is normal, the consistency of the DDS message data sent by the module under test, and whether the business flow of the module under test is normal after receiving the DDS message data sent by the simulation module.

[0048] Through the above steps, the source data distribution service DDS message sent by the business module to be tested is monitored; a pre-configured relationship configuration table is read, wherein the relationship configuration table is used to store a first mapping relationship between the source DDS message and the message structure of the response DDS message, and a second mapping relationship between the message structure and the test data, wherein the message structure is used to characterize the message type of the response DDS message to be simulated, and the test data is used to characterize the message content of the response DDS message to be simulated; the response DDS message of the source DDS message is simulated and arranged based on the relationship configuration table; the response DDS message is sent to the business module, and the response DDS message of the source DDS message is flexibly generated based on the relationship configuration table by configuring the first mapping relationship and the second mapping relationship in the relationship configuration table, thereby solving the technical problem in the related art that the related art cannot flexibly provide test data for the business module to be tested during the test process, and realizing flexible customization of the test process and test data during the DDS message simulation test.

[0049] In one implementation of this embodiment, simulating and arranging a response DDS message of the source DDS message based on the relationship configuration table includes: searching for a message structure that matches the source DDS message in the relationship configuration table, and generating test data that matches the message structure based on the relationship configuration table; filling the test data into the message structure, and arranging the response DDS message.

[0050] In one example, generating test data that matches the message structure according to the relationship configuration table includes: determining a generation rule for the test data based on the second mapping relationship, the second mapping relationship including a generation rule for the test data corresponding to the message structure, and generating test data that matches the message structure based on the generation rule.

[0051] Optionally, generating test data that matches the message structure based on the generation rule includes one of the following: if the generation rule is fixed configuration data, determining the fixed configuration data as test data that matches the message structure; if the generation rule is a static matching rule, determining the configuration field of the message structure based on the relationship configuration table, reading the static parameter value from the relationship configuration table, and determining the static parameter value as test data that matches the configuration field in the message structure; if the generation rule is a dynamic matching rule, determining the target field of the source DDS message and the response field of the response DDS message based on the relationship configuration table, reading the dynamic parameter value from the source DDS message, and determining the dynamic parameter value as test data that matches the response field in the message structure.

[0052] The simulation software provides the ability to publish business-related DDS messages. It then loads the relationship configuration table and matches received source DDS messages. Upon receiving a DDS message, the software first traverses the relationship configuration table and extracts the first and second mapping relationships if they exist. Based on the associated message structure in the relationship table and the test data configured for subsequent DDS messages, the simulation software then publishes response DDS messages to the source DDS messages one by one, implementing simulation testing.

[0053] In this embodiment, before reading the preconfigured relationship configuration table, it also includes: configuring the message response rules between the business module and the simulation module; configuring the message transmission rules between the business module and the simulation module based on the message response rules, wherein the message transmission rules are used to characterize the first mapping relationship and the second mapping relationship; and generating the relationship configuration table using the message response rules and the message transmission rules.

[0054] In one example, configuring the message response rules between the business module and the simulation module includes: responding to a user's first selection instruction, selecting the DDS interface of the business module to be tested, wherein the DDS interface is used to transmit the source DDS message; parsing the data structure of the DDS interface, wherein the data structure includes multiple fields; responding to a user's second selection instruction, selecting a target field from the data structure, wherein the target field is a field in the source DDS message associated with the response DDS message.

[0055] In another example, configuring the message response rules between the service module and the simulation module includes: responding to a first selection instruction of a user, selecting a DDS interface of the service module to be tested, wherein the DDS interface is used to transmit the source DDS message.

[0056] Still taking the business module to be tested A and the simulation module B as an example, when configuring the DDS message of the A module and the message response rule of the B module, a user first selects a DDS message (source DDS message) of the A module; according to the data structure information of the selected DDS message, the user selects a field (optional step) in the data structure that is concerned in the flow. For example, the data structure of the message is composed of studentNum, age, name, and grade, and after being sent to the B, the data value of the studentNum field (target field) will affect the data of some topics (such as the data of the subsequent response DDS message) in the B, so the user needs to mark the studentNum as the target field, and if the data of the subsequent flow has no correlation with any parameter carried by the source DDS message, no configuration is needed.

[0057] In one embodiment of the present embodiment, configuring the message transmission rule between the business module and the simulation module includes: determining a DDS interface of the business module to be tested based on the message response rule, wherein the DDS interface is used to transmit the source DDS message; configuring a message structure of a response DDS message of the source DDS message; and configuring test data of the message structure.

[0058] In one example, configuring the test data of the message structure includes: using fixed configuration data to configure first test data of the message structure.

[0059] In this example, a response DDS message received by the B after 1 step is configured, test data of the response DDS message is configured based on a default rule, and the data of the response DDS message uses default configuration data.

[0060] In one example, configuring the test data of the message structure includes: determining a plurality of message fields of the message structure, constructing a plurality of static parameter values of the plurality of message fields, and using the plurality of static parameter values to configure second test data of the message structure, wherein each static parameter value corresponds to a message field.

[0061] In this example, a response DDS message is configured after B receives the source DDS message. Test data is configured based on static rules, and the user constructs the corresponding test data according to the data structure. In this example, the test data is specified by the user, because the data structure of the response DDS message is fixed, and it only needs to be displayed to the user. The user fills in the expected test data corresponding to the field type in the data structure, and the backend assembles the message content of the response DDS message according to the information entered by the user. For example, the structure struct student{string num; string name; int age}; includes three or more message fields, and the user can fill in (202311725; Lihuan; 18) three corresponding non-static parameter values. The parameter information is filled in according to this agreed rule, and the backend parses and assigns values.

[0062] In another example, configuring the test data of the message structure includes: determining a target field in the source DDS message, and determining a response field associated with the target field in the response DDS message; and configuring the dynamic parameter value of the target field as third test data of the message structure.

[0063] In this example, a response DDS message is configured for B after it receives a source DDS message. Dynamic configuration involves assigning values ​​to response fields associated with the values ​​carried by the target fields selected during the message response rule phase. The response field for the test data is selected for the response DDS message, and the data value of the selected target field is populated into the currently configured field. For example, after module B receives a message from a source DDS message containing student information, B obtains the value of studentNum as 202311725. B needs to respond to a response DDS message configured in the relationship configuration table. Assume that the data structure of the response DDS message contains the structure structScores{string stuNo; float Chinese; float Math; float English;}. When assembling the content of the response DDS message, stuNo is the field that the user needs to dynamically configure. It should be populated with the value of studentNum in the source DDS message, i.e., 202311725. In this example, the dynamically configured field is Scores.stuNo, which corresponds to a field in the source DDS message sent by A.

[0064] In DDS communication, the interface agreement between publishers and subscribers typically includes data type definitions, message formats, security, and encryption, which serve as the foundation of the entire communication process. Based on established message data structure agreements, the present invention possesses all the DDS message capabilities involved in registration. Users then write configuration relationships, select source DDS messages to monitor, and, after monitoring corresponding messages, customize the simulation module's return and subsequent response DDS message data to be published. This embodiment implements a message-based process orchestration scheme to achieve a continuous and complete message interaction process, both receiving DDS messages sent by the module under test and generating subsequent DDS message responses to the received DDS messages.

[0065] Figure 3 The present invention is a flowchart for configuring a simulated DDS message in an embodiment of the present invention, including: configuring a DDS interface to be tested; determining whether attention needs to be paid to the DDS data to be tested; if so, configuring the data field to be paid attention to; if not, configuring a DDS interface to be sent subsequently (response DDS message); determining whether data of the DDS message to be tested needs to be used; if so, configuring the field to use the data of the DDS field to be tested; if not, continuing to determine whether manual configuration of test data is required; if so, filling in the test data according to the configured subsequent DDS interface data structure; if not, using default data for subsequent DDS message publishing.

[0066] This embodiment provides a universal message simulation test design method for testing service modules based on DDS Ethernet communication. Users configure the service of the module under test to link the communication interactions of the simulation module, automatically or manually simulating the test data of the module under test. Simulation can be completed simply by following the data conventions of the communication interfaces between the service modules. When testing a module under test, it is often necessary to generate test data based on different circumstances. In this embodiment, based on the agreed data format of the response DDS message, users provide a configuration method to specify the data interaction relationship to complete the generation and transmission of test data. This solves the problem of being unable to flexibly provide test data for the module under test during the test process. This design method is more universal and efficient.

[0067] Through the description of the above embodiments, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus the necessary general hardware platform, and of course it can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present invention is essentially or the part that contributes to the prior art can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for enabling a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in each embodiment of the present invention.
