[0041] Before providing a detailed description of the embodiments of this application, some of the nouns and terms involved in the embodiments of this application will be explained first. The nouns and terms involved in the embodiments of this application are subject to the following interpretations.

[0042] UUID stands for Universally Unique Identifier, and its purpose is to provide unique identification information for all elements in a distributed system.

[0043] ARXML files are XML file formats in the AUTOSAR standard, used to describe the software architecture and configuration information of automotive electronic software systems. They are a type of universal configuration / database file.

[0044] A MAP (Mapping File) is a file used to describe address mappings, storage allocations, or configuration information.

[0045] In some embodiments of one aspect of the present invention Figure 1 This is an optional flowchart of the interface testing method for in-vehicle Ethernet provided in the embodiments of this application. Figure 1 The method may include, but is not limited to, steps S100 to S500.

[0046] Step S100: Parse the first configuration file of the vehicle Ethernet and extract the message attributes of the vehicle Ethernet and the Ethernet signal information corresponding to the message attributes.

[0047] Step S200: Based on the message attributes and Ethernet signal information, determine the first write unit in the first write area, and write the Ethernet signal information to the first write unit accordingly.

[0048] Step S300: Parse the second configuration file of the vehicle Ethernet and extract the interface signal information corresponding to the Ethernet signal information based on the Ethernet signal information.

[0049] Step S400: Based on the message attributes and interface signal information, determine the second write unit in the second write area, and write the interface signal information to the second write unit accordingly; wherein, the first write area corresponds to the second write area.

[0050] Step S500: Traverse all matched first and second write regions to generate interface test cases.

[0051] Steps S100 to S500, as illustrated in this embodiment, involve parsing the first Ethernet configuration file to extract message attributes and Ethernet signal information, and writing them into the first write unit of the corresponding first write area. Using the Ethernet signal information as a retrieval condition, corresponding interface signal information is extracted from the second configuration file to match the Ethernet signal information with the interface signal information, thus avoiding omissions or incompleteness in test sequences during test cases. Based on the matched Ethernet signal information and interface signal information, a second write unit for writing interface signal information is determined. The first write area corresponds to the second write area. All matched first and second write areas are traversed to generate interface test cases corresponding to the Ethernet signal and the interface signal. Tests are performed based on the interface test cases to obtain test results. This effectively reduces the test cycle, improves the detection rate and efficiency of effective problem detection, and raises the testing threshold for domain controllers and the breadth of interface testing.

[0052] In some embodiments of S100, a first configuration file of the vehicle-mounted Ethernet is obtained, the first configuration file is parsed, and the message attributes of the Ethernet packets are extracted. Based on the message attributes, the corresponding Ethernet signal information is retrieved from the first configuration file.

[0053] In other words, the first configuration file of the vehicle Ethernet is parsed, the Ethernet packets in the first configuration file are used to determine the transmission and reception attributes of the Ethernet packets, and the corresponding input and output Ethernet signal information is determined based on the transmission and reception attributes of the packets.

[0054] The first configuration file is an ARXML file. Message attributes include: sending attributes and receiving attributes. Ethernet signal information includes: first signal name, transmission information, and transmission test values. Transmission information includes: signal value, signal type, signal length, message ID, transmit / receive type, and transmit / receive period.

[0055] In some embodiments of S200, a first write area is determined based on the transmit and receive attributes of the Ethernet packet, and a first write unit for writing Ethernet signal information is determined based on the Ethernet signal information in the first write area, and the Ethernet signal information is written into the first write unit accordingly.

[0056] The first write area can be a write area of ​​a memory, a write area of ​​a spreadsheet, or a buffer for temporary data storage. In this application, no specific restrictions are placed on the specific application of the write area.

[0057] Correspondingly, the first writing unit can be a writing unit of the writing area of ​​the memory, corresponding to one or more addresses of the memory, or a writing cell of the writing area of ​​a spreadsheet, or a storage unit of a buffer for temporary data storage. In this application, no specific application is restricted to the writing unit used to store or update Ethernet signal information.

[0058] In some embodiments of S300, a second configuration file of the vehicle Ethernet is obtained, the second configuration file is parsed, and the Ethernet signal information is used as a retrieval condition to extract interface signal information that matches the input and output of the Ethernet signal information.

[0059] The second configuration file is a map file. The interface signal information includes: the second signal name, interaction attributes, and interface test values.

[0060] In some embodiments of S400, based on the first write area determined in S200 and the interface signal information that matches the Ethernet signal information in S300, the second write area is determined by the first write area determined by the message attributes. For the Ethernet signal information and interface signal information that match each other, the first write area and the second write area correspond to each other in the write area, which is an input-output correspondence.

[0061] Based on the interface signal information, a second writing unit for writing interface signal information is determined in the second writing area, and the interface signal information is written to the second writing unit accordingly.

[0062] The second write area can be a write area of ​​a memory, a write area of ​​a spreadsheet, or a buffer for temporary data storage. In this application, no specific restrictions are placed on the specific application of the write area.

[0063] Correspondingly, the second writing unit can be a writing unit of the writing area of ​​the memory, corresponding to one or more addresses of the memory, or a writing cell of the writing area of ​​a spreadsheet, or a storage unit of a buffer for temporary data storage. In this application, no specific application is restricted to the writing unit used to store or update Ethernet signal information.

[0064] In some embodiments of S500, S400 has already completed the matching and correspondence of all Ethernet signal information and all interface signal information. Based on each matched pair of Ethernet signal information and interface signal information, interface test cases are generated.

[0065] Configure an automated testing environment, execute interface test cases, and obtain test results.

[0066] The automated testing environment includes: power supply, host computer and software, CAN communication equipment, and the controller under test.

[0067] In one embodiment, each pair of matched Ethernet signal information and interface signal information is used as input to generate a test case script. Based on the set test requirements, input signal values ​​are selected from the Ethernet signal information or interface signal information. Each signal value is used as input to generate a test case. Test cases can be generated by selecting specific signals based on user responses or by enumerating input signal values. Based on the selected input signal value, the corresponding expected output value is selected from the Ethernet signal information or interface signal information and written into the expected result verification section of the generated test case. The output format of the test results is defined, including a comparison between the expected output value and the actual value, as well as the overall test results.

[0068] In some embodiments of the present invention, S100, the process of extracting message attributes and Ethernet signal information corresponding to the message attributes includes:

[0069] S110: Based on the universally unique identifier of the Ethernet packet in the first configuration file, the packet attributes of the Ethernet packet are parsed.

[0070] S120, based on the universally unique identifier, determines the signal node corresponding to the Ethernet definition of the message attributes and the first signal name under the signal node.

[0071] S130 parses Ethernet packets based on the universally unique identifier to obtain the transmission information of Ethernet signals corresponding to the packet attributes and generates transmission test values.

[0072] S140: Based on the first signal name, transmission information, and transmission test values, Ethernet signal information is generated.

[0073] In some embodiments of S110, the Ethernet packets in the first configuration file are parsed, and the packet attributes of the Ethernet packets are identified and extracted based on the unique attribute UUID of the Ethernet packets, i.e., the universally unique identifier.

[0074] The message attributes include the receiver attribute and the sender attribute, which are the receiving attribute and the sending attribute, respectively.

[0075] For example, the Ethernet packets in the ARXML file are parsed, and the receiver and sender attributes of the Ethernet packets are identified and extracted based on the unique UUID attribute of the Ethernet packets.

[0076] In some embodiments of S120, the Ethernet signal node definition is determined based on a universally unique identifier, and the signal name under the signal node, i.e., the first signal name, is determined, as well as the basic attributes related to the signal.

[0077] Based on the characteristics of the universally unique identifier, the message attributes and the first signal name under the same universally unique identifier can correspond to each other.

[0078] For example, the Ethernet packet in the ARXML file is parsed, and the definition of the Ethernet type node and the signal name and related attributes of the signal node, such as the transmission type, are found based on the unique attribute UUID of the Ethernet packet.

[0079] In some embodiments of S130, the Ethernet message is parsed using a universally unique identifier to obtain the signal value, signal type, and signal length of the Ethernet signal. The signal value, signal type, and signal length are all transmission information of the Ethernet signal.

[0080] The transmitted information may also include other attributes or data, which are not limited in this application.

[0081] Based on the Ethernet packets parsed from the ARXML file, test input and output values ​​are generated to obtain the transmission test values.

[0082] In one embodiment, the transmission and reception period, transmission and reception method, and message ID of the parsed Ethernet message are also used as transmission information so that they can be recorded and written to the first writing unit.

[0083] Based on the characteristics of the universally unique identifier, the message attributes and transmission information under the same universally unique identifier can correspond to each other.

[0084] For example, based on the Ethernet packet's unique UUID attribute, the Ethernet packet is parsed to obtain the Ethernet signal value, signal type, and signal length. Based on the parsed ARXML file of the Ethernet packet, test input and output values ​​are generated to obtain the transmission test values.

[0085] In some embodiments of S140, Ethernet signal information is formed by combining the transmission test value, transmission information and first signal name determined in S110 to S130.

[0086] Through the above embodiments, by automatically identifying and parsing ARXML files and automatically identifying change points, the amount of manual operation is reduced, effectively shortening the testing cycle.

[0087] In some embodiments of the present invention, S200, the writing process of the first writing unit includes:

[0088] S210, determine the first write area based on the message attributes and the order in which the message attributes are extracted.

[0089] S220: Obtain the first write identifier of the first write unit in the first write area, match the first write identifier with the Ethernet signal information, and determine the first write unit corresponding to the Ethernet signal information being written.

[0090] In some embodiments of S210, as can be seen from S110, the message attributes include: receiver attribute and sender attribute. That is, receive attribute and send attribute.

[0091] Based on the message attributes and the extraction order of the message attributes, it is determined which number the current Ethernet signal is extracted from, and whether it belongs to the receiver attribute or the sender attribute, thereby confirming the first write area where the Ethernet signal information is written.

[0092] The first write region has multiple first write units.

[0093] In one embodiment, if the current Ethernet signal belongs to the receiving attribute and is the first one extracted, then the first write area is the first input area; if the current Ethernet signal belongs to the receiving attribute and is the Nth one extracted, then the first write area is the Nth input area.

[0094] In one embodiment, if the current Ethernet signal belongs to the transmission attribute and is the first one extracted, then the first write area is the first output area; if the current Ethernet signal belongs to the transmission attribute and is the Nth one extracted, then the first write area is the Nth output area.

[0095] For example, refer to Figure 2When the write area is the write area of ​​the memory, the write area of ​​the memory is divided into N output areas and N input areas. Each output area and each input area has multiple write units, and the output areas correspond to the input areas. If the current Ethernet signal belongs to the receive attribute and is the first one extracted, then the address of the first input area in the write area of ​​the memory is obtained. This first input area is the first write area for the current Ethernet signal. If the current Ethernet signal belongs to the transmit attribute and is the second one extracted, then the address of the second output area in the write area of ​​the memory is obtained. The second output area is used as the first write area. However, this is not the address of the first output area. The address of the first output area is used for subsequent corresponding interface signal information writing, and so on, until all Ethernet information is written. By using the area address, it is convenient to quickly locate and write signal information later.

[0096] For example, refer to Figure 2 When the write area is the write area of ​​a spreadsheet, the spreadsheet has N output rows and N input rows. Each output row and each input row has multiple write cells, and the output areas correspond to the input areas. If the current Ethernet signal belongs to the receive attribute and is the first one extracted, then the first input row is the first write area for writing the current Ethernet signal; if the current Ethernet signal belongs to the transmit attribute and is the second one extracted, then the second output row is the first write area for writing the current Ethernet signal. Note that the address of the first output row is not the address of the first output row; the address of the first output row is used for writing the corresponding interface signal information subsequently, and so on, until all Ethernet information is written.

[0097] In some embodiments of S220, the first write area has multiple first write units, and the Ethernet signal information is written to the first write unit according to the correspondence between the first write identifier of the first write unit and the Ethernet signal information.

[0098] The first write identifier can be a storage address identifier in memory, a row or column field in a spreadsheet, or a cache address identifier in a buffer that temporarily stores data. In this application, no specific restrictions are placed on the specific application of the write identifier.

[0099] For example, refer to Figure 2When the write area is the write area of ​​the memory, if the current Ethernet signal belongs to the receiving attribute and is the first one extracted, then the address of the first input area in the write area of ​​the memory is obtained. This first input area is the first write area where the current Ethernet signal is written. According to the storage address identifier of the write unit in the first input area, the first write unit corresponding to the first signal name in the current Ethernet signal information is determined through the correspondence with the Ethernet signal information, the first write unit corresponding to the signal value in the current Ethernet signal information is determined, and so on, the current Ethernet signal information is written to the first write area.

[0100] For example, refer to Figure 2 When the write area is the write area of ​​a spreadsheet, if the current Ethernet signal belongs to the receiving attribute and is the first one extracted, then the first row input area is the first write area for writing the current Ethernet signal; based on the corresponding row and column fields in the first row input area, through the correspondence with the Ethernet signal information, the first write unit corresponding to the first signal name in the current Ethernet signal information is determined, the first write unit corresponding to the signal value in the current Ethernet signal information is determined, and so on, the current Ethernet signal information is written to the first write area.

[0101] In some embodiments of the present invention, S300, the process of extracting interface signal information includes:

[0102] S310, using the first signal name as the search condition, extract the second signal name corresponding to the first signal name from the second configuration file.

[0103] S320, based on the transmitted information, determine the interaction attributes of the second signal name.

[0104] S330 uses the first signal name as the search condition and writes the retrieved interface test value according to the transmission test value.

[0105] S340 generates interface signal information based on the second signal name, interaction attributes, and interface test values.

[0106] In some embodiments of S310, based on Ethernet signal information and a second configuration file, the first signal name of the parsed Ethernet signal is used as a retrieval condition to extract and retrieve the second signal name containing the first signal name field from the second configuration file.

[0107] The second signal name is the internal interface name.

[0108] For example, based on Ethernet signal information and a MAP file, the first signal name of the parsed Ethernet signal is used as the search condition to extract and search for the second signal name containing the first signal name field in the MAP file.

[0109] In some embodiments of S320, the interaction attribute corresponding to the second signal name is determined based on the input / output attributes of the Ethernet signal in the search criteria.

[0110] The interaction attributes include output attributes and input attributes. Since they are based on the same UUID, the input and output attributes of Ethernet signals correspond to the message attributes of Ethernet packets.

[0111] In one embodiment, the interaction attribute corresponding to the second signal name is determined based on the transmit / receive type, i.e., input / output attribute, in the transmission information of the Ethernet signal in the search criteria.

[0112] For example, when the Ethernet signal in the search criteria is an input attribute, the interaction attribute of the retrieved interface signal is an output attribute, and the interface signal is the output; when the Ethernet signal in the search criteria is an output attribute, the interaction attribute of the retrieved interface signal is an input attribute, and the interface signal is the input.

[0113] In some embodiments of S330, the first signal name is used as the retrieval condition. The transmission test value generated by parsing the first configuration file in S100, i.e., the test input value or the test output value, is written into the second configuration file to retrieve the interface signal input and output values, i.e., the interface test values.

[0114] For example, the test input or test output values ​​generated by parsing the ARXML file in S100 are written into the interface signal input or output values ​​retrieved in the MAP file.

[0115] In some embodiments of S340, interface signal information is formed by combining the second signal name, interaction attribute, and interface test value determined in S310 to S330.

[0116] The interface signal information may also include information about other interface signals. This application does not limit the specific type of interface signal information.

[0117] Through the above embodiments, by using Ethernet signal information as the retrieval condition, the information of the corresponding interface signal is retrieved to achieve one-to-one matching, thereby avoiding problems such as test sequence omission, incomplete test sequences, and long processing time.

[0118] In some embodiments of one aspect of the present invention, S400, the writing process of the second writing unit includes:

[0119] S410 determines the second write area corresponding to the first write area based on the message attributes and interface signal information.

[0120] S420: Based on the second write identifier of the second write unit in the second write area, match the second write identifier with the interface signal information to determine the second write unit corresponding to the interface signal information.

[0121] In some embodiments of S410, as can be seen from S320, since they are based on the same UUID, the message attributes of the Ethernet packet and the input / output attributes of the Ethernet signal are consistent, and the input / output attributes of the Ethernet signal correspond to the interaction attributes of the interface signal. That is, if the Ethernet signal is the input, then the interface signal is the output; if the Ethernet signal is the output, then the interface signal is the input.

[0122] In one embodiment, the attribute position of the second write area is determined by the transmit / receive attributes of the Ethernet signal and the interaction attributes in the interface signal information, as determined by the message attributes. The write order position of the second write area is determined by the correspondence between the first and second write areas, thus defining the second write area. The positions of the first and second write areas correspond to each other, representing an input-output correspondence.

[0123] In other words, the attribute position of the second write area is determined by the send / receive attribute of the message attribute and the input / output attribute of the interaction attribute. Then, the writing order position of the second write area is determined by the order position of the first write area, thereby determining the writing position of the second write area.

[0124] For example, based on the matching Ethernet signals and interface signals of S300, when the message attribute is a receive attribute, that is, the first write area is an input area, and the interaction attribute of the interface signal is an output attribute, the interface signal is written as an output to the output area, that is, the second write area is an output area. According to the first write area, if the first write area is the first input area, then the second write area is the first output area.

[0125] For example, based on the matching Ethernet signals and interface signals of S300, when the message attribute is a transmission attribute, that is, the first write area is an output area, and the interaction attribute of the interface signal is an input attribute, the interface signal is written as input to the input area, that is, the second write area is an input area. According to the first write area, if the first write area is the Nth output area, then the second write area is the Nth input area.

[0126] In some embodiments of S420, the second write area has multiple second write units, and the interface signal information is written to the second write unit according to the correspondence between the second write identifier of the second write unit and the interface signal information.

[0127] The second write identifier can be a storage address identifier in memory, a row or column field in a spreadsheet, or a cache address identifier in a buffer for temporary data storage. In this application, no specific restrictions are placed on the specific application of the write identifier.

[0128] For example, when the write area is the write area of ​​the memory, if the second write area of ​​the current interface signal information is determined to be the first output area by S410; according to the storage address identifier of the write unit in the first output area, the second write unit corresponding to the second signal name in the current interface signal information is determined by the correspondence with the interface signal information, the second write unit corresponding to the interface test value in the current interface signal information is determined, and so on, and the current interface signal information is written to the second write area.

[0129] For example, when the writing area is the writing area of ​​a spreadsheet, if it is determined by S410 that the second writing area of ​​the current interface signal information is the Nth input area, then the Nth row input area is the second writing area for writing the current interface signal; based on the corresponding row and column fields in the Nth row input area, through the correspondence with the Ethernet signal information, the second writing unit corresponding to the second signal name in the current Ethernet signal information, the second writing unit corresponding to the interface test value in the current interface signal information, and so on, the current interface signal information is written to the second writing area.
