[0002] In the development of software for a UAV ground station, a large amount of downlink communication data is often required, and each of the communication data packets is based on an ICD protocol. Each ICD protocol is composed of a plurality of bytes or bits, and each byte or bit has a specific meaning. Therefore, when performing a function test, a test case needs to be generated for each byte or bit having a specific meaning.

[0044] For the purpose, technical solutions and advantages of the embodiments of the present application, the technical solutions of the embodiments of the present application will be described in more detail below. In the drawings, the same or similar notations represent the same or similar elements or elements with the same or similar functions throughout. The described embodiments are part of the embodiments of the present application, not all embodiments. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application. The embodiments of the present application will be described in detail below with reference to the drawings.

[0045] The embodiments of the present application will be described in detail below with reference to the drawings. Figures 1 to 8 The present application will be further described in detail.

[0046] The first aspect of the present application provides a method for automatically generating test cases for unmanned aerial vehicle downlink information, as shown in the following steps: Figure 1 As shown in the following steps:

[0047] Step one, get the ICD configuration file under the set path, parse the ICD configuration file to generate message configuration information;

[0048] Step two, generate test case data for each field of the message configuration information;

[0049] Step three, save the test case data to the test case file according to the set format.

[0050] The method for automatically generating test cases for unmanned aerial vehicle downlink information of the present application, first, in step one, get the ICD configuration file under the set path, parse the ICD configuration file to generate message configuration information, including:

[0051] Determine whether the set path exists, if yes, traverse all ICD configuration files under the set path, the ICD configuration file is written according to the set format;

[0052] Parse the ICD configuration file line by line to get the message configuration information;

[0053] Save the message configuration information.

[0054] As shown in the following steps: Figure 2As shown, all ICD configuration files in a specific directory are parsed. Each ICD configuration file is written in a specified format. Each line of data in the ICD configuration file contains information such as the start byte, end byte, start bit, end bit, field name, physical upper limit, physical lower limit, and data type. Each line of data is parsed and saved to the memory storage area where the class variable is located.

[0055] The automatic generation method of the UAV downlink information test case of this application, in step 2, such as Figure 3 As shown, several important parameters are used to generate test case data. Specifically, test case data is generated for each field of the message configuration information, including:

[0056] Get the value range of each field of the message configuration information. The fields are defined in bytes or bits.

[0057] Generate test case data for the physical upper limit, physical lower limit, and data type of each field, where:

[0058] When the data type is an enumeration type, all enumeration values ​​are generated;

[0059] When the data type is not an enumeration type, the maximum value, second maximum value, middle value, second minimum value, and minimum value are generated according to the physical precision.

[0060] In this embodiment, the generated test case data is in decimal format.

[0061] The method for automatically generating test cases for downlink information of drones in this application, in step 3, saves the test case data into a test case file according to a set format, including:

[0062] Determine whether the test case file exists;

[0063] If yes, clear the test case file and save the test case data in hexadecimal format to the test case file;

[0064] If not, create a new test case file and save the test case data in hexadecimal format to the test case file.

[0065] like Figure 4 As shown, the generated test case data is saved in a specific test case data file. When processing, it is necessary to determine whether the test case file exists, and then save the data according to the set format. In this embodiment, the test case file is named with the ICD number.

[0066] Based on the above-mentioned method for automatically generating test cases for downlink information of drones, the second aspect of this application provides a system for automatically generating test cases for downlink information of drones, such as Figure 5As shown, comprising:

[0067] ICD analysis module, for obtaining ICD configuration file under the set path, the ICD configuration file is parsed to generate message configuration information;

[0068] Use case data generation module, for each field of message configuration information generates test case data;

[0069] Case data saving module, for saving test case data into test case file according to the set format.

[0070] The unmanned aerial vehicle downlink information test case automatic generation system of the application further comprises: a UI design module for realizing the man-machine interaction function of the unmanned aerial vehicle downlink information test case automatic generation system through designing a UI interface.

[0071] The UI interface designed by the UI design module is the main interface of man-machine interaction. When designing the UI interface, the operation logic, operation habit and interface beauty of the user are mainly considered, so as to ensure that the system design has personality and characteristics, and the operation is simple. In the embodiment, the ICD multi-selection box layout effect is as shown in the figure Figure 6 Through the interface, the user selects the ICD configuration file to be parsed. When the user generates test case data, he only needs to select the ICD configuration file for which he wants to generate test case data. Clicking the "generate test case" button (such as Figure 7 ), the test case data can be saved to the specified test case file directory (such as Figure 8 ).

[0072] The unmanned aerial vehicle downlink information test case automatic generation method and system of the application automatically parses the standard ICD configuration file, generates specific decimal test case data according to the different data types of each byte or bit, and finally converts the decimal test case data into hexadecimal, generates hexadecimal ICD data packet and saves it into the test case file. The application can automatically parse the ICD configuration file, and automatically generate test case data according to each byte or bit in each ICD protocol. When saving the test case data, the test case data of the same ICD protocol is saved in a separate file, and the meaning of the byte or bit is indicated at the same time. This way of automatically generating test case can reduce the time cost and labor cost in testing, reduce the probability of error, and improve work efficiency.

[0073] The above is only a specific embodiment of the application, but the protection scope of the application is not limited thereto. Any changes or replacements within the technical range disclosed in the application can be easily thought of by those skilled in the art, which should be covered within the protection scope of the application. Therefore, the protection scope of the application should be subject to the protection scope of the claims.
