[0002] Since the birth of the first car, the automotive industry and technology have entered a period of rapid development. With the development of automobiles, a car has integrated an increasing number of electronic and electrical devices such as sensors and ECUs. However, the truly user-oriented and closely related aspects are the instrument panel and central control, as well as some passenger screens, air conditioning screens, heads-up display, etc., and the most important of these is the instrument panel function. Generally, if the central control panel or other interactive systems freeze or jam, it will not affect the basic use of the car, and the car can still run normally. However, if the instrument panel function fails, the entire car will no longer be able to continue to operate normally or will pose a significant safety risk.

[0032] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It should be understood that the specific implementation methods described herein are only used to illustrate and explain the embodiments of the present application and are not used to limit the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0033] Figure 1 The first flow chart of the automatic testing method according to the embodiment of the present application is schematically shown. Figure 1 As shown, in one embodiment of the present application, an automatic testing method is provided, which is applied to a test system, wherein the test system includes a test case automatic generation module, wherein the test case automatic generation module includes a data transmission module and multiple first data processing modules and multiple second data processing modules electrically connected to the data transmission module, including the following steps:

[0034] Step 101: for any first data processing module, control the data transmission module to send test data to the first data processing module, so that the first data processing module generates a corresponding test case according to the test data.

[0035] Step 102 : Control all first data processing modules that have generated test cases to send the corresponding test cases to the vehicle mainboard, so that the vehicle mainboard executes the corresponding test cases.

[0036] Step 103, the control data transmission module receives the status data fed back by each first data processing module that generates the test case within a preset interval, wherein the status data includes normal data fed back by the first data processing module in a normal state and abnormal data fed back in an abnormal state.

[0037] Step 104 : When any state data is abnormal data, determine whether the first data processing module corresponding to the state data is in an abnormal state.

[0038] Step 105 , the data transmission module is controlled to send the test data corresponding to the abnormal first data processing module to any second data processing module, so that the second data processing module generates a new test case according to the test data corresponding to the abnormal first data processing module.

[0039] Step 106 : Control the second data processing module that generates the new test case to send the new test case to the vehicle mainboard, so that the vehicle mainboard executes the new test case.

[0040] A test case is a description of a test task for a specific software product, embodying the test plan, method, technique, and strategy. The vehicle mainboard refers to the main control board in the vehicle instrument cluster. The test system may include an automatic test case generation module. The automatic test case generation module may include a data transmission module and multiple first data processing modules and multiple second data processing modules electrically connected to the data transmission module. For any first data processing module, the processor may control the data transmission module to send test data to the first data processing module, causing the first data processing module to generate a corresponding test case based on the test data. The processor may control all first data processing modules that have generated test cases to transfer the corresponding test cases to the vehicle mainboard, causing the vehicle mainboard to execute the corresponding test cases. The processor may control the data transmission module to receive status data fed back by each first data processing module that has generated a test case within a preset time interval. The status data includes normal data fed back by the first data processing module when it is in a normal state and abnormal data fed back when it is in an abnormal state. If any of the status data is abnormal, the processor may determine that the first data processing module corresponding to the status data is in an abnormal state. The processor can control the data transmission module to send the test data corresponding to the first data processing module in the abnormal state to any second data processing module, so that the second data processing module generates a new test case based on the test data corresponding to the first data processing module in the abnormal state. After the second data processing module generates the new test case, the processor can control the second data processing module that generated the new test case to send the new test case to the vehicle mainboard, so that the vehicle mainboard executes the new test case.

[0041] For example, Figure 2As shown, the test system may include a test case automatic generation module. The test case automatic generation module may include a main node corresponding to the data transmission module and multiple sub-nodes corresponding to the first data processing module or the second data processing module. Each sub-node may apply for registration (i.e., electrical connection) to the main node. When the main node acts as an executor that does not perform automated testing. For any sub-node corresponding to the first data processing module, the processor may control the main node to issue a task (i.e., test data) to the sub-node, so that the sub-node generates a corresponding test case based on the issued task. The processor may control all sub-nodes that have generated test cases to issue the corresponding test cases to the vehicle mainboard and hardware devices, so that the vehicle mainboard and hardware devices can execute the corresponding test cases. The processor may control the main node to receive status data fed back by each sub-node that has generated a test case within a preset interval. The status data includes normal data fed back by the sub-node when processing in a normal state and abnormal data fed back when processing in an abnormal state. When any status data is abnormal data, the processor may determine that the sub-node corresponding to the status data is in an abnormal state. The processor can control the main node to send the test data corresponding to the sub-node in an abnormal state to the sub-node corresponding to any second data processing module, so that the sub-node generates a new test case based on the test data corresponding to the sub-node in the abnormal state. The processor can control the sub-node that generates the new test case to send the new test case to the vehicle main board and hardware equipment, so that the vehicle main board and hardware equipment execute the new test case. In the case where the main node serves as an executor for performing automated testing, the processor can control the main node to generate corresponding test cases based on its own test data while sending test data to the sub-node, and send the generated test cases to the vehicle main board and hardware equipment, so that the vehicle main board and hardware equipment execute the corresponding test cases.

[0042] In one embodiment, the method also includes: after controlling all first data processing modules that have generated test cases to send corresponding test cases to the vehicle mainboard, controlling each first data processing module that has generated a test case to feedback status data to the data transmission module within a preset interval; when any first data processing module that has generated a test case does not feedback status data within the preset interval, sending a prompt message to the data transmission module; controlling the data transmission module to send the test data corresponding to the first data processing module that has not fed back status data to any second data processing module, so that the second data processing module generates a new test case based on the test data corresponding to the first data processing module that has not fed back status data.

[0043] After controlling all first data processing modules that have generated test cases to send the corresponding test cases to the vehicle mainboard, the processor can control each first data processing module that has generated a test case to feedback status data to the data transmission module within a preset interval. In the event that any first data processing module that has generated a test case does not feedback status data within the preset interval, the processor can send a prompt message to the data transmission module. After sending the prompt message, the processor can control the data transmission module to send the test data corresponding to the first data processing module that did not feedback status data to any second data processing module, so that the second data processing module generates a new test case based on the test data corresponding to the first data processing module that did not feedback status data.

[0044] For example, Figure 2 As shown, the test system may include a test case automatic generation module. The test case automatic generation module may include a main node corresponding to the data transmission module and multiple sub-nodes corresponding to the first data processing module or the second data processing module. Each sub-node may apply to the main node for registration (i.e., electrically connected). For any sub-node corresponding to the first data processing module, the processor may control the main node to send tasks (i.e., test data) to the sub-nodes, so that the sub-nodes generate corresponding test cases according to the tasks sent. The processor may control all sub-nodes that have generated test cases to send the corresponding test cases to the vehicle main board and hardware devices, so that the vehicle main board and hardware devices can execute the corresponding test cases.

[0045] After controlling all subnodes that have generated test cases to send the corresponding test cases to the vehicle mainboard and hardware, the processor can control each subnode that has generated a test case to feedback status data within a preset interval. If any subnode that has generated a test case fails to feedback status data within the preset interval, the processor can send a prompt message to the master node. The failure of a subnode that has generated a test case to feedback status data within the preset time period may be caused by unstable feedback lines, resulting in loss of status data; or it may be caused by an internal fault in the subnode, resulting in feedback status data exceeding the preset interval.

[0046] The processor can control the master node to send test data corresponding to subnodes that have not fed back status data to any subnode corresponding to the second data processing module, so that the subnode generates a new test case based on the test data corresponding to the subnode in the abnormal state. After the subnode generates the new test case, the processor can control the subnode that generated the new test case to send the new test case to the vehicle mainboard and hardware devices, so that the vehicle mainboard and hardware devices execute the new test case.

[0047] In one embodiment, the test system also includes multiple power modules and multiple bus modules that are electrically connected to multiple first data processing modules and the vehicle main board respectively, and controls all first data processing modules that have generated test cases to send corresponding test cases to the vehicle main board so that the vehicle main board executes the corresponding test cases, including: for any first data processing module that has generated a test case, controlling the first data processing module to send a first control instruction to the corresponding power module, so that the power module outputs a power parameter of a preset value to the vehicle main board according to the first control instruction; for any first data processing module that has generated a test case, controlling the first data processing module to send a second control instruction to the corresponding bus module, so that the bus module outputs a start signal to the vehicle main board according to the second control instruction; controlling the vehicle main board to execute the test case after receiving the power parameter and the start signal.

[0048] The test system also includes a plurality of power modules and a plurality of bus modules that are electrically connected to the plurality of first data processing modules and the vehicle mainboard respectively. The processor can control all the first data processing modules that have generated test cases to send the corresponding test cases to the vehicle mainboard, so that the vehicle mainboard executes the corresponding test cases. Specifically, for any first data processing module that has generated a test case, the processor can control the first data processing module to send a first control instruction to the corresponding power module, so that the power module outputs a power parameter of a preset value to the vehicle mainboard according to the first control instruction. For any first data processing module that has generated a test case, the processor can control the first data processing module to send a second control instruction to the corresponding bus module, so that the bus module outputs a start signal to the vehicle mainboard according to the second control instruction. The processor can control the vehicle mainboard to execute the test case after receiving the power parameter and the start signal.

[0049] In one embodiment, the vehicle main board includes a display module, and the method further includes: after executing the test case, obtaining the execution result of the vehicle main board; collecting display information of the display module within a preset time length, and obtaining each frame icon in the display information; comparing each frame icon with the target icon corresponding to the execution result; when any frame icon is consistent with the target icon, determining that the display function corresponding to the test case in the display module is normal.

[0050] After the vehicle's mainboard executes the test case, the processor can obtain the execution results of the vehicle's mainboard. The processor can collect the display information of the display module within a preset time period and obtain each frame icon in the display information. After obtaining each frame icon, the processor can compare each frame icon with the target icon corresponding to the execution result. If any frame icon matches the target icon, the processor can determine that the display function corresponding to the test case in the display module is normal.

[0051] In one embodiment, the vehicle mainboard further includes a CAN bus, and the method further includes: after the bus module outputs a start signal to the vehicle mainboard according to the second control instruction, determining whether the start signal exists on the CAN bus; and if the start signal exists on the CAN bus, determining that the vehicle mainboard successfully receives the start signal. The CAN bus is an in-vehicle bus protocol. Various devices can be mounted on the CAN bus, and signals sent by all devices are sent to the CAN bus.

[0052] After the bus module outputs the start signal to the vehicle mainboard according to the second control instruction, the processor can determine whether there is a start signal on the CAN bus. If there is a start signal on the CAN bus, the processor can determine that the vehicle mainboard has successfully received the start signal.

[0053] In one embodiment, the test system also includes an adapter module electrically connected to the display module, which collects display information of the display module within a preset time length and obtains each frame icon in the display information, including: controlling the adapter module to collect display information and converting the display information into data in high-definition video format; obtaining each frame icon in the data in high-definition video format.

[0054] The processor can collect display information from the display module within a preset time period and obtain each frame of icons in the display information. Specifically, the processor can control the adapter module to collect the display information and convert the display information into data in a high-definition video format. After obtaining the data in the high-definition video format, the processor can obtain each frame of icons in the data in the high-definition video format.

[0055] In one embodiment, the test system further includes an image acquisition module, and acquiring display information of the display module within a preset time period includes: controlling the image acquisition module to acquire display information of the display module within the preset time period.

[0056] The processor can test that the system further includes an image acquisition module that acquires display information of the display module within a preset time period. Specifically, the processor can control the image acquisition module to acquire display information of the display module within a preset time period.

[0057] For example, Figure 3As shown, the test system may include a computer, a programmable power supply (i.e., a power module), a CAN device (i.e., a bus module), an LVDS adapter (i.e., an adapter module) and a camera (i.e., an image acquisition module). Among them, the computer includes a data transmission module, multiple first data processing modules and multiple second data processing modules. The computer can open 4 USB interfaces (communication interfaces), which are respectively connected to the programmable power supply, the CAN device, the LVDS adapter, the camera and the vehicle instrument central control motherboard (i.e., the vehicle mainboard). Among them, the vehicle instrument central control motherboard may include an instrument screen (i.e., a display module), a CAN bus and a central control screen. The vehicle instrument central control motherboard also includes a power port and a LOG port (query port).

[0058] The processor can control the computer to generate test cases. For any generated test case, the processor can determine the specified maximum voltage, maximum current, overvoltage protection voltage value, and current protection current value of the test case. The processor can control the computer to send a first control instruction to the control port of the programmable power supply through the USB interface connected to the programmable power supply, so that the programmable power supply outputs preset power parameters to the power port of the automobile instrument central control motherboard according to the first control instruction. The power parameters include the maximum voltage, maximum current, overvoltage protection voltage value, and current protection current value. The processor can control the computer to send a second control instruction to the CAN device through the USB interface connected to the CAN device, so that the CAN device outputs a CAN signal to the CAN bus of the automobile instrument central control motherboard. After the CAN device outputs the CAN signal to the CAN bus of the automobile instrument central control motherboard, the processor can determine whether there is a CAN signal on the CAN bus. If there is a CAN signal on the CAN bus, it is determined that the automobile instrument central control motherboard successfully received the CAN signal.

[0059] When it is determined that the power parameters of the automobile instrument central control mainboard are configured successfully and the CAN signal is successfully received, the processor can control the computer to send the test case through the USB interface connected to the LOG port of the automobile instrument central control mainboard. And control the automobile instrument central control mainboard to execute the test case. After the automobile instrument central control mainboard executes the test case, the processor can obtain the execution result of the automobile instrument central control mainboard. At the same time, through line 1, the processor can control the computer to send an acquisition instruction to the LVDS adapter through the USB interface connected to the LVDS adapter, so that the LVDS adapter collects the display information of the instrument screen within a preset time length through the LVDS Input (acquisition port), and converts the display information into HDMI (high-definition video) format information to be transmitted to the computer through the HDMIOutput (output port). The processor can control the computer to obtain each frame icon in the HDMI format information.

[0060] Through line 2, the processor can also control the computer to send a capture command to the camera via the USB interface connected to the camera, so that the camera can capture the instrument screen display information within a preset time period. The instrument screen and camera can be placed in a dark box. The processor can control the camera to send the captured display information to the computer to obtain each frame of the display information.

[0061] The processor can compare each frame icon with the target icon corresponding to the execution result. When any frame icon is consistent with the target icon, the processor can determine that the display function corresponding to the test case in the display module is normal.

[0062] In one embodiment, Figure 4 As shown, the test system may include a computer and a hardware device connected to the computer, and the hardware device may communicate with the vehicle mainboard. The application on the computer may use Python 3.8 (test framework). Python 3.8 may send data to the distributed task packaging and allocation module, and assign tasks to the Pytest (test framework) module. The Pytest module may perform initialization operations, and after initialization is completed, Pytest may call the use case automatic generation module. The use case automatic generation module may scan the test case data (.json file, data exchange format), and generate data in .py format (file format) after performing data parsing and rule detection on the test case data through submodules. After generating the data in .py format, the data in .py format may be returned to the use case generation module for the use case generation module to call. The use case generation module may call the data in .py format to generate test cases, and send the test cases to the use case execution module. The use case execution module may initialize the hardware devices connected to the computer. Among them, the hardware devices may include LVDS or cameras, CAN devices, programmable power supplies, ADB (debug bridge) or other LOG interfaces. After initialization is complete, you can start the CAN submodule, set the programmable power supply, set the offline configuration, send CAN signals, and compare images to confirm that the test case execution is complete. After the test case execution is complete, you can use the Allture module (a multi-language test reporting tool) to generate a test case execution report.

[0063] Specifically, if Figure 5As shown, the processor can control the computer to initialize the connected hardware. After hardware initialization is complete, the processor can control the computer to launch the CAN tool, which continuously sends signals to the vehicle mainboard to maintain normal operation. The processor can also control the computer to power on the programmable power supply, which sets the voltage output to the vehicle mainboard. For example, it can set the voltage and maximum current, as well as the overvoltage protection voltage and overcurrent protection current, to ensure stability of the vehicle mainboard. The processor can control the CAN device to send offline configuration information, so that the vehicle mainboard can configure the corresponding ports based on the offline configuration information. After the vehicle mainboard's port configuration is complete, the processor can control the CAN device to send a CAN signal to the vehicle mainboard's CAN bus and obtain the signal value on the CAN bus to determine whether the signal value matches the signal value of the CAN signal. If the signal value matches, the processor can control the computer to send a test case to the vehicle mainboard, causing the vehicle mainboard to execute the corresponding test case. The processor can control the computer to capture a real-time screenshot of the vehicle mainboard's instrument panel via a camera or LVDS, and compare the captured screenshot with a template image. The template image refers to the target image corresponding to the test case's execution result on the vehicle's mainboard. The processor controls the computer to determine the comparison result. If the screenshot and the template image are consistent, the corresponding display function on the instrument panel can be determined to be normal. If the screenshot and the template image are inconsistent, the corresponding display function on the instrument panel can be determined to be abnormal.

[0064] The above technical solution controls the data transmission module to send test data to any first data processing module, so that the first data processing module generates a corresponding test case based on the test data; controls all first data processing modules that have generated test cases to send the corresponding test cases to the vehicle mainboard, so that the vehicle mainboard executes the corresponding test cases; controls the data transmission module to receive status data fed back by each first data processing module that has generated test cases within a preset time interval, wherein the status data includes normal data fed back when the first data processing module is in a normal state and abnormal data fed back when it is in an abnormal state; if any status data is abnormal data, determines that the first data processing module corresponding to the status data is in an abnormal state; controls the data transmission module to send the test data corresponding to the first data processing module in the abnormal state to any second data processing module, so that the second data processing module generates a new test case based on the test data corresponding to the first data processing module in the abnormal state; and controls the second data processing module that has generated the new test case to send the new test case to the vehicle mainboard, so that the vehicle mainboard executes the new test case. The above technical solution can realize the automated generation and automated testing of test cases, shorten the testing time, improve the testing efficiency, reduce the labor cost, and obtain more accurate test results.
