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

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

[0046] Step S100 , parsing a first configuration file of the in-vehicle Ethernet, extracting message attributes of the in-vehicle Ethernet and Ethernet signal information corresponding to the message attributes.

[0049] Step S400 , determining a second writing unit in a second writing area according to the message attributes and the interface signal information, and writing the interface signal information into the second writing unit accordingly; wherein the first writing area corresponds to the second writing area.

[0050] Step S500: traverse all matching first writing areas and second writing areas to generate interface test cases.

[0051] In steps S100 to S500 shown in the embodiment of the present application, by parsing the first configuration file of the Ethernet, the message attributes and Ethernet signal information are extracted, and the information is written into the first write unit in the corresponding first write area. The Ethernet signal information is used as the retrieval condition, and the corresponding interface signal information is extracted in the second configuration file to match the Ethernet signal information with the interface signal information, so as to avoid the problem of missing or incomplete test sequences in the test case; according to the matched Ethernet signal information and the interface signal information, the second write unit for writing the interface signal information is determined, the first write area corresponds to the second write area, all matching first write areas and second write areas are traversed, and an interface test case corresponding to the Ethernet signal and the interface signal is generated. The test is performed according to the interface test case to obtain the test result, thereby effectively reducing the test cycle, and improving the detection rate and test efficiency of effective problem detection, thereby improving the test threshold of the domain controller and the extensiveness of the interface test.

[0052] In some embodiments of S100, a first configuration file of the in-vehicle Ethernet is obtained, the first configuration file is parsed to extract message attributes of the Ethernet message, and corresponding Ethernet signal information is retrieved from the first configuration file according to the message attributes.

[0053] That is, the first configuration file of the vehicle Ethernet is parsed, the transceiver attributes of the Ethernet message are determined according to the Ethernet message in the first configuration file, and the corresponding input and output Ethernet signal information is determined according to the transceiver attributes of the message.

[0054] The first configuration file is an ARXML file. Message attributes include sending attributes and receiving attributes. Ethernet signal information includes a first signal name, transmission information, and a transmission test value. The transmission information includes a signal value, signal type, signal length, message ID, transceiver type, and transceiver cycle.

[0055] In some embodiments of S200, the first writing area is determined according to the receiving and sending properties of the Ethernet message, and the first writing unit for writing the Ethernet signal information in the first writing area is determined according to the Ethernet signal information, and the Ethernet signal information is written into the first writing unit accordingly.

[0056] The first writing area may be a writing area of ​​a memory, a writing area of ​​an electronic spreadsheet, or a buffer for temporarily storing data. In this application, no specific restrictions are imposed on the specific application objects of the writing 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 ​​the spreadsheet, or a storage unit of the buffer for temporarily storing data. In this application, no specific restrictions are made on the specific application objects of the writing unit used to store or update Ethernet signal information.

[0058] In some embodiments of S300 , a second configuration file of the vehicle-mounted Ethernet is obtained, the second configuration file is parsed, and the Ethernet signal information is used as a search 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: a second signal name, an interaction attribute, and an interface test value.

[0060] In some embodiments of S400, based on the first write area determined by S200 and the interface signal information that matches the Ethernet signal information in S300, the second write area to be written is determined by determining the first write area determined by the message attributes. Then, for the Ethernet signal information and the 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 relationship.

[0061] According to the interface signal information, a second writing unit for writing the interface signal information in the second writing area is determined, and the interface signal information is correspondingly written into the second writing unit.

[0062] The second writing area may be a writing area of ​​a memory, a writing area of ​​an electronic spreadsheet, or a buffer area for temporarily storing data. In this application, no specific restrictions are imposed on the specific application objects of the writing 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 ​​the spreadsheet, or a storage unit of the buffer for temporarily storing data. In this application, no specific restrictions are made on the specific application objects of the writing unit used to store or update Ethernet signal information.

[0064] In some embodiments of S500, all Ethernet signal information and all interface signal information are matched to each other through S400. An interface test case is generated based on each pair of matched Ethernet signal information and interface signal information.

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

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

[0067] In one embodiment, each pair of matching Ethernet signal information and interface signal information is used to generate the input of a test case script. Based on the set test requirements, an input signal value is selected from the Ethernet signal information or the interface signal information, and each signal value is used as an input to generate a test case. A test case can be generated by selecting a specific signal based on a user response, or input signal values ​​can be selected in an enumerated manner. Based on the selected input signal value, a corresponding expected result output value is selected from the Ethernet signal information or the interface signal information and written into the expected result check section of the produced test case. The output format of the test result is compiled, and the test result includes: a comparison result between the expected result output value and the actual value, and the overall test result.

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

[0069] S110: parse and obtain message attributes of the Ethernet message according to the universal unique identifier of the Ethernet message in the first configuration file.

[0070] S120: Determine, according to the universal unique identifier, a signal node defined in Ethernet corresponding to the message attribute and a first signal name under the signal node.

[0071] S130, parsing the Ethernet message according to the universal unique identifier, obtaining transmission information of the Ethernet signal corresponding to the message attribute, and generating a transmission test value.

[0072] S140, based on the first signal name, transmission information and transmission test value, forming Ethernet signal information.

[0073] In some embodiments of S110, the Ethernet message in the first configuration file is parsed, and the message attribute of the Ethernet message is identified and extracted based on a unique attribute UUID (universally unique identifier) ​​of the Ethernet message.

[0074] Among them, the message attributes include: receiver attributes and sender attributes, that is, receiving attributes and sending attributes.

[0075] Exemplarily, the Ethernet message in the ARXML file is parsed, and the receiver attribute and the sender attribute of the Ethernet message are identified and extracted based on the unique attribute UUID of the Ethernet message.

[0076] In some embodiments of S120, based on the universal unique identifier, an Ethernet signal node definition is determined, a signal name under the signal node, ie, a first signal name, is determined, and basic attributes related to the signal are also determined.

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

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

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

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

[0081] According to the Ethernet message parsed in the ARXML file, test input and output values ​​are generated to obtain transmission test values.

[0082] In one embodiment, the transceiver cycle, transceiver mode, and message ID of the Ethernet message obtained by parsing are also used as transmission information so as to be recorded and written into the first writing unit.

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

[0084] For example, the Ethernet message is parsed according to the unique attribute UUID of the Ethernet message to obtain the signal value, signal type and signal length of the Ethernet signal. According to the Ethernet message parsed in the ARXML file, the test input and output values ​​are generated to obtain the transmission test value.

[0085] In some embodiments of S140 , the transmission test value, the transmission information, and the first signal name determined in S110 to S130 are combined to form Ethernet signal information.

[0086] Through the above embodiment, ARXML files are automatically identified and parsed, change points are automatically identified, manual operations are reduced, and the test cycle is effectively shortened.

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

[0088] S210 : Determine a first writing area according to message attributes and the order in which the message attributes are extracted.

[0089] S220 , obtaining a first writing identifier of a first writing unit in the first writing area, matching the first writing identifier with the Ethernet signal information, and determining a first writing unit corresponding to the writing of the Ethernet signal information.

[0090] In some embodiments of S210, it can be known from S110 that the message attributes include: receiver attributes and sender attributes, that is, receiving attributes and sending attributes.

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

[0092] The first writing area has a plurality of first writing units.

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

[0094] In one embodiment, if the current Ethernet signal has a sending attribute and is the first extracted, the first writing area is the first output area; if the current Ethernet signal has a sending attribute and is the Nth extracted, the first writing area is the Nth output area.

[0095] For example, referring 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 is of the receiving attribute and is the first to be extracted, the address of the first input area in the write area of ​​the memory is obtained. The first input area is the first write area written by the current Ethernet signal; if the current Ethernet signal is of the sending attribute and is the second to be extracted, 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. Among them, it is not the address of the first output area. The address of the first output area is used for writing the corresponding interface signal information later. And so on, until all Ethernet information is written, the area address facilitates the rapid positioning and writing of the subsequent signal information.

[0096] For example, referring to Figure 2 When the write area is a spreadsheet write area, the spreadsheet has N rows of output areas and N rows of input areas. Each row of the output area and each row of the input area has multiple write cells, and the output areas correspond to the input areas. If the current Ethernet signal is of the receive attribute and is the first to be extracted, the first row of the input area is designated as the first write area for the current Ethernet signal. If the current Ethernet signal is of the transmit attribute and is the second to be extracted, the second row of the output area is designated as the first write area for the current Ethernet signal. The address of the first row of the output area is not the address of the first row of the output area, as it is used to write the corresponding interface signal information later. This continues in this manner until all Ethernet information is written.

[0097] In some embodiments of S220, the first writing area has a plurality of first writing units, and the Ethernet signal information is written into the first writing units according to the correspondence between the first writing identifiers of the first writing units and the Ethernet signal information.

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

[0099] For example, referring 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 to be extracted, then the address of the first input area in the write area of ​​the memory is obtained, and the 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, 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, and 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 into the first write area.

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

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

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

[0103] S320: Determine an interactive attribute of the second signal name according to the transmission information.

[0104] S330: Using the first signal name as a search condition, and writing the interface test value obtained by the search according to the transmission test value.

[0105] S340: Form interface signal information according to the second signal name, the interaction attribute, and the interface test value.

[0106] In some embodiments of S310, based on the Ethernet signal information and the second configuration file, the second signal name containing the first signal name field is extracted and retrieved from the second configuration file using the parsed first signal name of the Ethernet signal as a search condition.

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

[0108] Exemplarily, based on the Ethernet signal information and the MAP file, the first signal name of the Ethernet signal obtained by parsing is used as a search condition, and the second signal name containing the first signal name field is extracted and searched in the MAP file.

[0109] In some embodiments of S320 , the interactive attribute corresponding to the second signal name is determined according to the input and output attributes of the Ethernet signal in the search condition.

[0110] The interactive attributes are output attributes and input attributes. Because they are based on the same UUID, the input and output attributes of Ethernet signals correspond to the message attributes of Ethernet messages.

[0111] In one embodiment, the interaction attribute corresponding to the second signal name is determined according to the transceiver type, ie, the input / output attribute, in the transmission information of the Ethernet signal in the search condition.

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

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

[0114] Exemplarily, the test input value or test output value generated by parsing the ARXML file in S100 is written into the interface signal input value or output value retrieved from the MAP file.

[0115] In some embodiments of S340 , the second signal name, interaction attribute, and interface test value determined in S310 to S330 are combined to form interface signal information.

[0116] The interface signal information may also include information of other interface signals, and the specific type of the interface signal information is not limited in this application.

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

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

[0119] S410: Determine a second writing area corresponding to the first writing area according to message attributes and interface signal information.

[0120] S420 : Match the second write identifier with the interface signal information according to the second write identifier of the second write unit in the second write area, and determine the second write unit to which the interface signal information is written.

[0121] In some embodiments of S410, S320 indicates that, due to the same UUID, the message attributes of the Ethernet message and the input and output attributes of the Ethernet signal are consistent, and the input and output attributes of the Ethernet signal correspond to the interaction attributes of the interface signal. That is, if the Ethernet signal is input, the interface signal is output, and if the Ethernet signal is output, the interface signal is input.

[0122] In one embodiment, the attribute position of the second write area is determined based on the transceiver attributes of the Ethernet signal determined by the message attributes and the interaction attributes in the interface signal information. The first write area determined by the message attributes and the corresponding relationship between the first write area and the second write area are used to determine the writing sequence position of the second write area, thereby determining the second write area. The position of the first write area corresponds to the position of the second write area, forming an input-output correspondence relationship.

[0123] That is to say, the attribute position of the second write area is determined by the sending and receiving attributes of the message attributes and the input and output attributes of the interaction attributes, and then the writing sequence position of the second write area is determined by the sequence position of the first write area, thereby determining the writing position of the second write area.

[0124] For example, based on the Ethernet signal and interface signal that match each other in S300, when the message attribute is a receiving attribute, that is, the first writing area is an input area, and the interaction attribute of the interface signal is an output attribute, the interface signal is written to the output area as an output, that is, the second writing area is the output area. According to the first writing area, if the first writing area is the first input area, the second writing area is the first output area.

[0125] For example, based on the Ethernet signal and interface signal that match each other in S300, when the message attribute is a sending attribute, that is, the first writing area is the output area, and the interaction attribute of the interface signal is an input attribute, the interface signal is written into the input area as input, that is, the second writing area is the input area. According to the first writing area, if the first writing area is the Nth output area, the second writing area is the Nth input area.

[0126] In some embodiments of S420, the second writing area has a plurality of second writing units, and the interface signal information is written into the second writing units according to the correspondence between the second writing identifiers of the second writing units and the interface signal information.

[0127] The second write identifier can be a storage address identifier in the memory, a row and column field in a spreadsheet, or a cache address identifier of a buffer for temporarily storing data.
