With the development of automobile intellectualization, the internet of vehicles service is also popularized as an indispensable ring of intelligent automobiles. The remote control function is a core function of the car networking service, allows a car owner to send instructions such as opening and closing air conditioner windows and the like by using the mobile phone app, and forwards the instructions to the vehicle-mounted terminal (tbox) through the car networking cloud server, so that the remote control of the car is realized.
Nowadays, vehicles supporting the internet of vehicles service are more and more, and vehicle-mounted terminals tbox accessing to the internet of vehicles cloud server are also increased. As a core service of the internet of vehicles, remote control services are under increasing concurrent pressure. Today, there is no specific method for remotely controlling the service pressure measurement because each service provider has a different service form. If the performance is in problem, the service of the internet of vehicles of hundreds of thousands or even millions of users can be directly influenced. Therefore, a solution method for performing a performance test on the remote control service is very important.

FIG. 1 is a flow chart of the overall business logic of the present invention.
Detailed Description
The invention relates to a cloud platform of a vehicle networking system, a LoadRunner tool for realizing performance test and a grafana resource monitoring platform. Before implementation, the core services (the core services include login service, remote control service, data transceiving encryption and decryption service, database and the like) of the test environment are ensured to be normal; ensuring that a login port of the LoadRunner tool closes double-break authentication; and ensuring that the test data is normal.
The following describes a performance testing method for implementing the car networking remote control service by the LoadRunner tool in the embodiment of the present invention with reference to fig. 1:
1. simulating vehicle-mounted terminal tbox login
The LoadRunner tool firstly needs to start a plurality of threads, the threads are used for simulating the connection between the vehicle-mounted terminal tbox and the test cloud platform TSP, and the process is called login. When logging in, the target address is logged in to select the entry ip of the test server, and the port is used 8910 (the port does not use bidirectional authentication). And after the Socket communication is successfully established, each thread sends out a prepared login message. The registration message transmitted by each thread includes information, encryption scheme, request mode, and the like corresponding to the simulated in-vehicle terminal tbox.
2. Judging the login state
When receiving a Login message sent by a thread, the test cloud platform TSP returns an answer message, where the answer message includes a flag bit "0 fa001010 f" indicating whether the thread-simulated vehicle-mounted terminal Tbox successfully logs in, further, the thread judges whether the answer message includes the flag bit "0 fa001010 f", and if the answer message includes the flag bit "0 fa001010 f", the thread-simulated vehicle-mounted terminal Tbox is considered to be successfully logged in, and a LoadRunner tool is used to print information "Car Control sunrate _ Step02_ Tbox log", LR _ PASS "indicating that the logging is successful. If the flag bit "0 fa001010 f" is not included in the response message, it is considered that the thread-simulated vehicular tbox fails to log in, and information "cardntrolsucrate _ Step02_ TboxLogin", LR _ fali "indicating that the log-in fails is printed.
3. The test cloud platform receives a remote control instruction input by a thread simulation user, and issues a control message containing the remote control instruction to the tbox of the simulation vehicle-mounted terminal
The method comprises the following steps: each thread simulates a user to send a remote control instruction to the testing cloud platform TSP by calling an interface of the testing cloud platform, if the interface of the testing cloud platform is successfully called, the testing cloud platform TSP can successfully receive the corresponding remote control instruction, further, the testing cloud platform TSP sends a control message containing the remote control instruction to the corresponding thread through the interface, and meanwhile, the interface feeds back a taskid parameter to the corresponding thread. If the test cloud platform is not successfully called, the corresponding thread actively closes the connection with the test cloud platform TSP, and the steps of establishing the connection with the test cloud platform TSP and sending the remote control instruction to the test cloud platform TSP are repeated again after a period of time.
The process that the testing cloud platform TSP and each thread carry out control instruction and control message interaction needs to be interacted through the same interface machine core, therefore, interface parameters of the testing cloud platform need to be associated with the corresponding thread and the testing cloud platform TSP, and a parameter association tool carried by a LoadRunner tool is used for processing, so that the condition that the interface parameters transmitted every time are consistent and effective is guaranteed. After the control message containing the remote control instruction is successfully sent, the interface of the test cloud platform returns a taskid parameter to the corresponding thread, and the taskid parameter is used in the step of obtaining the control result in the later step, so that the taskid parameter is processed and stored as a global variable.
4. Thread receiving control message
After receiving the control message sent by the testing cloud platform TSP, each thread asserts by taking out the received control message, if the control message contains '00 c 80001', the control message is received successfully, and otherwise, the control message is failed. Then, the failure or success result of receiving the control message is printed, and when the failure or success result is printed, the printing format is as follows: "Car Control subcrate _ Step04_ Tbox Receive Control CMD", LR _ PASS; when the printing fails, the printing format is as follows: "Car Control SucRate _ Step04_ Tbox Receive Control CMD", LR _ fail.
5. Thread simulation vehicle-mounted terminal tbox responds
And fifthly, after the control message from the test cloud platform TSP is successfully received, each thread starts to simulate the vehicle-mounted terminal tbox to respond to the control result. Each thread also carries out message response in the form of an appointed message, and the point of attention here is that the control type of the receipt message sent by the thread to the testing cloud platform TSP is consistent with the control type of the control message sent by the testing cloud platform TSP to the thread, and variable correlation processing is carried out on the parameter in advance to ensure that the receipt message responded by each thread can correspond to the received remote control instruction. After receiving a response message (return message) of the thread, the testing cloud platform TSP returns a final confirmation message (return message) to the thread, wherein the return message information includes a control type and a receiving result, and the return message is intercepted and asserted, and the execution result of the current control is judged and printed for each different control type message.
6. Querying control results
And the sixth step is the final control result query, which does not affect the previous business process, and each thread acquires the final result of the currently executed remote control event from the corresponding interface based on the taskid parameter and prints the final result.
7. Script parameterization
The performance test needs a large amount of test data to support, so that the data of a single terminal cannot meet the concurrent requirement. Under the requirement of sending control instruction interface Parameters, parameterizing the unique identification tuid of the terminal and the associated data thereof, and storing the parameterized identification tuid and the associated data in a Parameters file. Therefore, under the condition of great concurrency, data does not conflict when multiple virtual users run scripts simultaneously.
8. Scene setting
After the script is debugged, setting a scene after a LoadRunner tool is loaded, wherein the setting is roughly divided into a concurrent growth mode, a duration and an ending mode. Here we adopt a heuristic pressure scenario, gradually increasing the amount of concurrency, and can spy on the service bottleneck.
9. Performance monitoring of applications
The performance monitoring mainly adopts a monitoring window carried by a tool, and the TPS and the response time are observed in a key mode. And on the other hand, the hardware resources of the service container are monitored by using the grafna, and the performance of the current service is comprehensively evaluated.
The method provided by the invention is based on the LoadRunner tool, and can realize the simulation of automatic response to the remote control instruction issued by the cloud platform, thereby simulating a large concurrent remote control event and verifying the throughput, response time and stability of the TPS system of the service.
