[0002] Automated testing is a method of software testing that uses specialized software tools to automatically execute test cases and compare the actual results with the expected results. This method can significantly improve the efficiency and accuracy of testing, reducing the time and cost required for manual testing. Automated testing is being increasingly applied in industries such as mobile phones, automobiles, and factory manufacturing, and the demand for testing efficiency in these industries is becoming more intense.

[0003] In the prior art, the use of image recognition technology in mobile phone function automated testing has matured. As the functions of automotive head units become more abundant, the number of test cases to be tested also increases. It is necessary to optimize test tools and methods based on traditional automated testing to improve testing efficiency and reduce labor costs.

[0004] The prior art has the following technical problems:

[0005] 1. Traditional automated testing needs to call the interfaces of the automotive host to complete automated testing. However, for OEM vehicle projects, the automotive host suppliers are different, the interface documents written by each supplier are different, and the platform construction is not yet perfect. As a result, traditional interfaces need to be re-adapted for each project and the amount of modification is large.

[0006] 2. Currently, the automotive host has relatively strict permission management for calling interfaces, and permissions affect the use of traditional automated testing scripts, resulting in a significant reduction in testing efficiency. The traditional automated testing method of calling interfaces cannot simulate operations such as touching by users in a real vehicle.

[0007] 3. Currently, there are many types of energy vehicles and their intelligence is becoming more abundant, and the functions to be tested are also increasing. The scalability of traditional testing methods cannot meet the growing testing requirements, and it is necessary to continuously change the scripts to implement stress testing.

[0057] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0058] Figure 1 The flowchart of a stress testing method for automotive OTA upgrade according to an embodiment of the present invention is shown. As Figure 1 shown, a stress testing method for automotive OTA upgrade according to an embodiment of the present invention is for the PC side, and the method includes:

[0059] Configure the OTA upgrade stress testing task and obtain the image template of the in-vehicle host interface; wherein, the image template is used to identify specific elements on the vehicle-side host interface;

[0060] In this embodiment, the specific elements include buttons and menu items. It is also necessary to set parameters such as the threshold and matching method of image recognition to ensure the accuracy and robustness of recognition.

[0061] Establish a connection with the vehicle-side host through the ADB line;

[0062] Set the number of stress testing times for the OTA upgrade stress testing task, and use the automated stress testing program to automatically perform stress testing according to the number of stress testing times, and based on the image template, identify the target elements on the vehicle-side host interface through the image recognition method, and perform the operations of stress testing according to the identified target elements;

[0063] After reaching the set number of stress testing times, generate a stress testing report through the automated stress testing program.

[0064] Optionally, establishing a connection with the vehicle-side host through the ADB line specifically includes: casting the vehicle-side host interface to the PC side through the ARDC method.

[0065] In this embodiment, as Figure 2 shown, it is a schematic diagram of the connection between the PC side and the vehicle-side host, Figure 2 which provides the connection methods between the PC side and the vehicle-side host at the physical layer, transport layer, and application layer. At the physical layer, it is connected through the industry-standard ADB line to establish communication between the ADB server on the PC side and the ARBD in the vehicle-side host. At the transport layer, it is connected through the TCP connection method. At the application layer, the vehicle-side screen is cast to the PC side through the ARDC program. After the above connection, subsequent image recognition is realized, and automatic click operations are performed based on the recognition results.

[0066] Optionally, it is also used for the vehicle-end host, including:

[0067] Monitoring whether the OTA upgrade stress test task is received;

[0068] If the OTA upgrade stress test task is not received, end the test and generate a test failure report;

[0069] If the OTA upgrade stress test task is received, send a preparation completion instruction to the PC side. The preparation completion instruction is used for the automated stress test program to enter the secondary APP menu of the vehicle-end host using an image recognition method, and perform an OTA upgrade operation on the vehicle-end host according to the OTA upgrade stress test task.

[0070] In this embodiment, the vehicle-end interface monitors whether the OTA upgrade stress test task is received. If the OTA upgrade stress test task is not obtained within 10 minutes, the task status is detected. If it times out, the OTA upgrade stress test task ends and a report is generated. If the OTA upgrade stress test task is received, enter the secondary APP menu through the image recognition automation method and enter the OTA upgrade according to the vehicle upgrade button clicked by the automated stress test program.

[0071] Such as Figure 3 shown, it is a schematic flowchart of the vehicle-end host entering the OTA upgrade stage. In this embodiment, the vehicle-end host enters the upgrade stage according to the click of the automated stress test program, and waits for the automated stress test program to configure the OTA upgrade. After the upgrade is completed, the power is turned off, and the result of this upgrade is recorded. Then, the automated stress test program determines whether the preset number of stress test times is reached. If not, the vehicle-end host is stress-tested again.

[0072] Optionally, identifying the target element on the vehicle-end host interface by an image recognition method, and performing the stress test operation according to the identified target element specifically includes:

[0073] Using the PyAutoGUI method to capture the screen shot of the current vehicle-end host interface;

[0074] Using the OpenCV method to perform image recognition on the screen shot to obtain the position coordinates of the target element to be clicked;

[0075] Using the PyAutoGUI method to perform a click operation according to the position coordinates and record the result of each click operation.

[0076] Optionally, obtaining the position coordinates of the target element to be clicked specifically includes:

[0077] Using the OpenCV method to read the screen shot and the image template;

[0078] Use the Shape attribute method to obtain the attribute data of the image template, where the attribute data includes: height, width, and number of channels;

[0079] Based on the attribute data, use the matchTemplate method to perform similarity matching between the screenshot and the image template to obtain a matching result matrix;

[0080] Use the minMaxLoc method to obtain the minimum and maximum values in the matching result matrix, obtain the matching position of the image template according to the maximum value, and calculate the upper left corner coordinates of the image template according to the matching position and the minimum value;

[0081] Calculate the lower right corner coordinates of the image template based on the upper left corner coordinates and the attribute data, and calculate the position coordinates of the image template based on the upper left corner coordinates and the lower right corner coordinates; where the position coordinates of the image template are the position coordinates of the target element to be clicked.

[0082] In this embodiment, as Figure 4 shown, it is a schematic diagram of the image recognition process. In terms of image recognition, it provides a coordinate tuple of the area to be matched for the automatic click function. The present invention provides a method for image recognition and automatic click developed using the python language. In image recognition, mainly two libraries, opencv and pyautogui, are used. Opencv is a widely used library in computer vision and image processing. In the present invention, the pyautogui library is called to perform screen capture and automatic click operations, and the screenshot to be matched is passed into the image recognition program.

[0083] Use the functions in the opencv library to read the screenshot and the target template and obtain the height, width, and number of channels of the target template through the Shape attribute. Use the matchTempalte template matching function to perform matching by using the standard square difference method. Return a matrix of the same size as the target template, and each value represents the matching degree of the corresponding position.

[0084] The minMaxLoc function is used to find the minimum and maximum values in the matrix and their positions. Since the square difference matching is used, the coordinates of the minimum value are the upper left corner coordinates of the best matching position. By calculating the target at the upper left corner, the lower right corner coordinates of the matching area can be obtained. By calculating the upper left corner and lower right corner coordinates of the required matching area, the coordinate tuple of the center point can be obtained. After obtaining the coordinate tuple, the automatic click operation can be started.

[0085] Optionally, establishing a connection with the vehicle-end host through the ADB line specifically includes:

[0086] Use the ADB client on the PC side to check whether there is a running first ADB server on the vehicle host;

[0087] If there is, establish a connection with the first ADB server through the ADB client;

[0088] If not, start the second ADB server automatically and establish a connection with the ADB daemon process of the vehicle host through the second ADB server.

[0089] In this embodiment, open the command line or terminal on the PC side and run the check command to check the status of the currently connected device and the ADB server: if the device list is displayed in the command output, it means that there is already a running ADB server (the first ADB server) on the vehicle host, then run the self-start command to start a new ADB server (the second ADB server); then establish a connection with the ADB daemon process of the vehicle host through the second ADB server. After the connection is established, the ADB server can send service requests to the second ADB server.

[0090] Based on the same principle as the method shown in Figure 1 , the embodiment of the present invention also provides a stress testing system for automotive OTA upgrade, as shown in Figure 5 , for the PC side, the system includes:

[0094] A report module, configured to generate a stress test report through the automated stress testing program after the set number of stress test times is reached.

[0095] Optionally, it is also used for the vehicle host, including:

[0097] If the OTA upgrade stress test task is not received, end the test and generate a test failure report;

[0098] If an OTA upgrade stress test task is received, a preparation completion instruction is sent to the PC side. The preparation completion instruction is used for the automated stress test program to enter the secondary APP menu of the vehicle host using an image recognition method and perform an OTA upgrade operation on the vehicle host according to the OTA upgrade stress test task.
