[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.

In one example, the transmission device 106 can 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 is a flow chart of a DDS-based simulation test method according to an embodiment of the present invention, such as Figure 2 As shown, the process includes the following steps:

[0037] Step S202, monitoring the source service 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 business module. The execution subject of this embodiment is a simulation module that executes the simulation test.

[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, reading a preconfigured relationship configuration table, 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 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;

[0041] For example, the business module to be tested is A, and the simulation module is B. Because A's business needs to be tested, the orchestration scheme configures B's behavior and test data, and the entire process is based on DDS message interaction. The test process needs to consider two points: 1. After the A module sends a DDS message, according to the normal business process, the B module needs to respond to A with what DDS message after receiving the message, and 2. The data content carried in the DDS message responded by the B module. The above two points are respectively implemented through the first mapping relationship and the second mapping relationship in the relationship configuration table, which are explained here respectively:

[0042] Assume that in the entire business flow, after A sends message 1 to B, it needs to receive message 2 (or even message 3, message 4...) from B in order to drive A module to continue to execute according to normal business. For example, A requests B to adjust the air conditioner temperature to 26° (currently 30°), and B needs to respond that the air conditioner temperature has been adjusted to 26° before A can confirm that the air conditioner temperature has been adjusted to 26°. If A does not receive this response message from B, it will not make subsequent temperature changes (still believe that the current temperature is 30°).

[0043] Taking the above air conditioning temperature as an example, when B responds to A's air conditioning temperature, for example, assuming that the lowest setting of module B can only be 27°, module B considers that any request from A for a temperature setting lower than the lowest setting of 27° is set to 27°. If A requests 26°, then B's response message is 27°. If A requests 28°, then B's response DDS message is 28°. Or at this time, module B is limited and always responds to other data. Therefore, the simulation module B not only responds to A's message, but also supports custom response data values ​​in this arrangement.

[0044] Here, the first mapping relationship in the relationship configuration table is: the relationship between the source DDS message sent by module A and the DDS message type responded by simulation module B, for example, message a of A corresponds to message b of B, and message c of A corresponds to message d and message e of B, 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 by an example: the relationship information between the DDS message data sent by A and the test data released by the subsequent response DDS message sent by B, that is, the generation method of the test data used by B when responding to the message of A, 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; the 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 the flexible customization of the test process and test data during the DDS message simulation test process.

[0049] In one implementation of the present embodiment, simulating and arranging a response DDS message of the source DDS message based on the relationship configuration table includes: searching the relationship configuration table for a message structure that matches the source DDS message, and generating test data that matches the message structure according to 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 matching 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 matching 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] Under the premise that the simulation software provides the ability to publish DDS messages related to the business, it matches the received source DDS message by loading the relationship configuration table. That is, whenever a DDS message is received, the relationship configuration table is traversed first. If it exists in the configuration table, the first mapping relationship and the second mapping relationship are extracted. The simulation software publishes the response DDS messages of the source DDS messages one by one according to the message structure associated with it in the relationship table and the test data of the subsequent DDS message configuration to realize the simulation test.

[0053] In this embodiment, before reading the preconfigured relationship configuration table, it also includes: configuring message response rules between the business module and the simulation module; configuring 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 a DDS interface of the business module to be tested, wherein the DDS interface is used to transmit the source DDS message; parsing a 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 that is 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 as A and the simulation module as B as an example, when configuring the DDS message of module A and the message response rules of B, the user first selects a DDS message of A (source DDS message); according to the selected DDS message data structure information, the user selects a field of interest in the process in the data structure (optional step). For example, the data structure of the message consists of studentNum, age, name, and grade. After being sent to B, the data value of the studentNum field (target field) will affect the data of certain topics in B (such as the data of the subsequent response DDS message), so the user needs to mark studentNum as the target field. If the data of the subsequent process is not associated with any parameters carried by the source DDS message, no configuration is required.

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

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

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

[0060] In one example, configuring the test data of the message structure includes: determining several message fields of the message structure, constructing several static parameter values ​​of the several message fields, and configuring second test data of the message structure using the several static parameter values, 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. Since the data structure of the response DDS message is fixed, 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. 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 after B receives the source DDS message. The dynamic configuration configures the assignment of the response field associated with the value carried by the target field selected in the message response rule stage. The response field for the test data needs to be configured in the response DDS message. According to the data value of the selected target field, it is filled into the currently selected configured field. For example, after the B module receives the message in the source DDS message, the source DDS message carries the student information, and the value of studentNum obtained by B is 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 message content of the response DDS message, stuNo is the field that the user needs to dynamically configure. stuNo should be filled with the value of studentNum in the source DDS message, that is, 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 the publisher and the subscriber usually includes data type definition, message format, security and encryption, etc., which is the basic part of the entire communication. The present invention is based on the established message data structure agreement and has all the DDS message capabilities involved in registration. The user then writes the configuration relationship, selects the source DDS message to be monitored, and after monitoring the corresponding message, the custom simulation module returns and the response DDS message data to be published subsequently. This embodiment is a message-based process arrangement invented to achieve a continuous and complete message interaction process, which not only receives the DDS message sent by the module to be tested, but also makes a subsequent DDS message response to the received DDS message.

[0065] Figure 3 The 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; judging whether it is necessary to pay attention to the DDS data to be tested; if so, configuring the data field to be paid attention to; if not, configuring the DDS interface to be sent subsequently (response DDS message); judging whether it is necessary to use the data of the DDS message to be tested; if so, configuring the field to use the DDS field data to be paid attention to; if not, continuing to judge whether it is necessary to manually configure the test data; if so, filling in the test data according to the configured subsequent DDS interface data structure; if not, the subsequent DDS message release uses the default data.

[0066] This embodiment provides a general message simulation test design method for service module testing based on DDS Ethernet communication. The user connects the service of the module to be tested with the communication interaction of the simulation module through configuration, automatically / manually simulates the test data of the module to be tested, and can complete the simulation only according to the data agreement of the communication interface between the service modules. When testing the module to be tested, it is often necessary to create some test data according to different situations. In this embodiment, the user provides a configuration method to specify the data interaction relationship based on the agreed data format of the response DDS message to complete the generation and sending of test data, which solves the problem of not being able to flexibly provide test data for the module to be tested during the test process. This design method is more general and more efficient.

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