In recent years, with the application of technologies such as internet of vehicles, unmanned, 5G, V X and the like in the vehicle-mounted field, automobiles not only meet the travel requirements of people, but also develop towards digitization, informatization and entertainment. The traditional in-vehicle bus CAN bus in the vehicle-mounted bus architecture is not capable of meeting the high-concurrency network demand of big data. The vehicle bus architecture is in urgent need of a new bus to meet the information exchange requirement in the vehicle. The on-board ethernet is then emerging.
In our daily life, a computer is plugged into a network cable to surf the internet, and a standard Ethernet is used, wherein the Ethernet is used as a physical connection medium, and a software protocol stack is required to be constructed on the Ethernet. In-vehicle ethernet, like a standard protocol stack, also requires a software protocol stack to be built on top of it so that the application layer can conveniently use ethernet technology. Unlike conventional ethernet, on-board system buses have stringent requirements for the effectiveness of messaging, the time consumed for messaging, and the time for message response. These differences also place higher demands on the test method of the on-board system bus. The functional test and the performance test of the software are highly expected to have a convenient, easy-to-use, quick and accurate vehicle-mounted Ethernet test method.
Conventional software testing typically implements software functionality testing manually or semi-manually, while software performance testing is typically a rough test through process monitoring. The function and performance test of the vehicle-mounted Ethernet protocol stack is generally carried out on the protocol stack interface by manually writing test cases, and when the requirements are changed, the test cases are required to be rewritten, so that time and labor are wasted, and human errors are easily introduced.

step 2-1) interface data structure analysis; obtaining interface data types of the grammar tree, generating call reply data content according to the data types, generating a data structure for expanding function parameters when the call reply data content is expanded until the types are POD types, then reading test metadata in a test database, generating type examples, and assigning the metadata to the examples; if the data of the target data type is required to be specified, a default value can be declared and filled in the database;
step 2-2) interface function analysis; acquiring interface function names of a grammar tree, determining function actions by analyzing the interface functions, generating a calling relation frame code according to the calling relation analysis of the function names, and determining the content of the generated code according to the difference of the function actions;
step 2-3) the test program source code collects the test interface parameters in step 2-1) and the test code frame in step 2-2), generates the test program source code, and inserts the test process monitoring code into the test code; the monitoring code refers to the process, time and content of function call when the program runs, and can be used for testing user analysis; the brief summary test code generating module is used for obtaining function names and function parameters, reading a test database, inserting an operation monitoring code, and finally generating a test code;
step 3) sending the test codes to a test code compiling module, compiling corresponding test program files according to the types of the platforms, and transmitting the test program files adapting to different platforms to a program deployment and operation control module, wherein the embedded scenes are as follows: ssh remote login control, scp program deployment, adb installation deployment, and protocol stack test through a program deployment and operation control module;
step 4) the running process information is sent to a test report generating module to generate a test report, and the test report generating module is used for collecting the tested information and arranging the report according to the information time stamp; and finally, generating a test report according to a certain format.
The invention will be further illustrated with reference to specific examples.
The SOME/IP protocol stack test includes:
1. calling an availability test: the client calls a protocol stack interface, and whether the server can receive corresponding data or not;
2. interface data serialization and anti-serialization testing: the sending end sends the data to the opposite side through SOME/IP protocol stack, the parameters need to be packed according to the agreed data format, the process is called serialization; after receiving the data, the receiving end unpacks the data according to the appointed format, and the process is called reverse serialization; judging whether the data of the receiving party and the sending party are consistent or not during the test;
3. calling a time sequence and delay test: when the interface tests, the client calls the interface to request data from the server, or the server actively notifies the registered event receiver of the event, and the interface of the protocol stack is triggered in the correct sequence and under the allowed delay in the processes.
The SOME/IP protocol stack interface is divided into such several types: method call, method return, event notification, attribute setup, and attribute acquisition interface.
As shown in fig. 4, the tested protocol stack code is first introduced into the compiling and testing server, and the code generating module in the compiling and testing server will analyze the interface code of the SOME/IP protocol stack and generate a syntax tree according to the flow as in fig. 2. The grammar tree passes the interface information to the test code generation module. For SOME/IP protocol stack method call and test case generation of method return, the input parameters of the method call need to acquire the "fingerprint" of the data (the fingerprint refers to the check byte generated by a certain algorithm, hash, CRC and the like can be used), in FIG. 3, when call reply data content is generated, the "fingerprint" is also generated; with the "fingerprint" it is then necessary to trigger an interface function that invokes the protocol stack to pass data from one end to the other. The compiling and testing server needs to add extra testing links as "testing channels" in order to control SOME/IP protocol stack sending and monitor data receiving during testing, and the "testing channels" suggest the use of other protocol stacks such as TCP/IP. "TestChannel" in fig. 5 means "test channel". The "test channel" is inserted into the test code during the process of monitoring code generation. The test channel records the fingerprint and the time stamp of the data sent by the sending end, and if the data needs to be returned to the calling end, the test channel correspondingly records the fingerprint and the time stamp of the returned data, and the test server judges the sending, receiving and returning reliability of the data through the test channel.
Method call and method return test: the overall flow is shown in fig. 5:
1. the compiling and testing server sends a 'TestChannel' method to a testing platform A through a 'testing channel', and the testing platform A triggers a corresponding protocol stack interface to send data to a testing platform B;
2. after receiving the message sent by the protocol stack, the test platform B generates a corresponding check byte by using a check function;
3. if the message needs to be returned, returning data and generating a return data check byte, and then sending calling information to a compiling and testing server through a testing channel;
4. after receiving the test data, the test platform A generates check bytes in the same way as the sending end and transmits the data to the compiling and testing server through a test channel.
Event notification test: when testing the event notification interface:
1. the compiling and testing server triggers the testing platform B to send event information;
2. when the test platform B monitors the event method to be triggered, the fingerprint and the time stamp are collected, and then call data are sent to a test and compiling server through a test channel;
3. the test platform B sends the fingerprint and the time stamp of the event to the compiling and testing server through the test channel after the event is sent;
4. the compiling and testing server analyzes the acquired information. Confirming whether the event is triggered correctly or not through analysis; the overall flow is shown in fig. 6.
And (3) testing the attribute: and the same method is called.
