Due to the bulkiness of the system, for example: the intelligent driving automobile has various functions of vehicle-mounted central control and various functions of vehicle-mounted instruments which are very complex, and needs to be tested one by one to see whether the various functions are normally displayed, whether the picture of each application is normally displayed and whether the display of each system controlled by the automobile body is normal. In the prior art, the manual test is adopted, but the test is very time-consuming and labor-consuming, omission also occurs, habits of everyone are different, and a test result has large deviation. The test is also improved by factory production personnel, namely, manual test is not adopted, application programs on a central control display screen and an instrument display screen are simulated to be manually touched by means of an intelligent mechanical arm, and screen icons are clicked one by one to test whether the picture is normal or not. However, due to the fact that the area of the central control display screen or the manual display screen is limited, the intelligent mechanical arm is difficult to guarantee that the position needing to be touched is accurately found in a large number of touch processes, deviation can occur frequently, the test structure is inaccurate or the test is interrupted, and errors are reported frequently, so that the auxiliary of personnel is needed in the test process, and if measures are taken, the tester can correct the mechanical arm timely.

In step S2, establishing the connection between the host computer and the device to be tested includes:

step S21, using SFTP protocol to assign IP address and port number to the device to be tested to connect to the upper computer, after connection is successful, the upper computer sends user information and message to carry out authorization authentication with the device to be tested;

step S22: judging whether the authentication is successful or not, if the authentication is unsuccessful, prompting disconnection by a popup window and sending a notification of connection failure; if the authentication is successful, the connection is kept and the connected confirmation information is returned.

Referring to fig. 6, fig. 6 is a schematic flow chart of an automatic upgrading method for a device to be tested in this embodiment, and in step S2, the specific steps of writing an upgrade file into the device to be tested and upgrading the device to be tested by using an upper computer include:

step S23, the upper computer transmits the upgrade file to the equipment to be tested by adopting an SFTP protocol and judges whether the upgrade file is successfully transmitted or not, if the upgrade file is successfully transmitted, the step S24 is executed, and if the upgrade file is failed to be transmitted, an execution failure prompt is returned;

specifically, the test cases are divided into key test cases and non-key test cases according to the operating state of the device to be tested, the key test cases are closely related to the safety of the vehicle, such as the engine state, the brake state, the oil temperature state, the light state, the steering control, the reversing radar, the camera and the like, and the non-closely related test cases are not closely related to the safety of the vehicle, such as: radio broadcasting, music playing, an air conditioning system, a Bluetooth system, a seat adjusting system and the like;

in the process of waiting for equipment testing, the central control test can be carried out after the vehicle instrument is tested. For each test case, according to whether the function can maintain operation or not, a main function and a slave function are defined in the test case, wherein the main function is defined to enable the basic function of the sub item to be tested to maintain normal operation, and the slave function is defined to be an auxiliary function which does not influence the normal operation of the sub item to be tested, and is mostly optimization of the function. Such as: in a radio, a function of receiving a broadcast signal and normally receiving and playing a sound is a main function. The slave function may specifically be a style of the display content as the display interface.

Specifically, when a test signal is applied to the test device, for example: the simulation manual touch of the corresponding application program icon, for example, the audio-video playing APP (application) needs to be tested, and a certain function of the APP currently being tested and running can be known through a signal simulating the manual touch of the screen, such as a resistance value and a position coordinate generated by manually clicking the screen in the program record, and the position coordinate and the resistance value generated by the screen. When the instrument display test is carried out, for example, a speed signal, such as a signal of 80km/h per hour, can be given to the system, whether the display of the instrument display screen is normal or not can be observed.

If the key test case is adopted to test the equipment to be tested, the test can be stopped when the function of the equipment to be tested fails, and the time is saved. Because the key test cases relate to the safety of the automobile, the problems are more, and if the test has problems, the system can automatically inform developers to adjust. The non-critical test case does not relate to driving safety, so that the normal use of the automobile cannot be influenced even if the function of the non-critical test case is abnormal, and the subsequent debugging of the bug can be completed in the subsequent development process. By adopting the method, the test time of the equipment to be tested can be saved, and the test resources are reduced.

s41, aiming at each test case, carrying out matching learning on the feature picture and the pattern by using NIVISION in advance;

s42, using NIVISION to compare the set picture of the expected result after multiple learning with the current test result, and judging whether the picture is in a preset threshold range, if so, executing the step S43, otherwise, recording the current error and storing the current error in a test report, and continuing to execute the next test;

specifically, the test result is derived from a signal transmitted from the monitoring device, in this embodiment, the monitor is a camera, the camera monitors the image of the device to be tested, the monitoring image is transmitted to the upper computer, and the upper computer receives the image and compares the image with a preset image to compare the similarity of the image and the preset image.

Because the test result of the implementation is obtained by adopting monitoring equipment such as a camera to shoot images, the control right of the equipment to be tested does not need to be completely obtained. Because the automobile relates to driving safety, in many times, the ECU control right of the equipment to be tested, such as a central control unit and an instrument, is used for driving safety, the upgrading process is prevented from being attacked and changed by viruses, and the control right of the equipment is not completely opened. In the test process, the corresponding analog signal quantity is sent to the equipment to be tested only according to the test case, and the picture signal shot by the monitor is transmitted to the upper computer for analysis, so that the control authority of the equipment to be tested is prevented from being completely acquired.

S43, judging whether the test case is the last test case, if not, continuing to execute the next test; if the test case is the last test case, the test process is ended, and a test passing report is generated.

What has been described above is only a preferred embodiment of the present invention, and the present invention is not limited to the above examples. It is clear to those skilled in the art that the form in this embodiment is not limited thereto, and the adjustable manner is not limited thereto. It is to be understood that other modifications and variations, which may be directly derived or suggested to one skilled in the art without departing from the basic concept of the invention, are to be considered as included within the scope of the invention.
