Here, the test program needs to be started after the Android is started, and the single board can receive the test signal sent by the test control box after the test program is started.
And 160, reading the USB flash disk boot file.
Because the test board reads the USB disk boot file through the USB interface, the test board in 160 can synchronously complete the USB test. The startup file in the usb disk may also contain data required for testing, such as a channel table required for testing the RF interface.

However, the test program in the method can be started only after the Android is started, and the test computer can determine the test result according to the display result output by the test single board only after the function of the test single board is stably output and displayed. The testing time for testing each function of the single board can reach 2 minutes to 3 minutes, so that the testing time is long, and the overall testing efficiency is low.
FIG. 3 shows a schematic flow chart of a test method 200 of an embodiment of the present invention. The method 200 comprises:

Here, the test board is started to the BOOT or the operating system kernel, and after the driver is initialized, each hardware port or interface of the test board can normally run.
In the embodiment of the invention, the port of the test single board can be an input port or an output port. When the port is an input port, the testing method 100 is executed by the testing board. At this time, obtaining port data generated by the test board according to the test sequence includes:

and generating the port data according to the test sequence.
Here, the test control box stores the test sequence in advance, and the test board stores the comparison data corresponding to the test sequence in advance. For example, the test sequence may be stored in a storage area of the test control box before the test control box is shipped from the factory, or the test sequence may be written in advance in the storage area in the test control box. The comparison data may be stored in a storage area (e.g., a flash memory) of the test board before the test board leaves the factory.
In addition, the test control box may store a plurality of test sequences in advance, the plurality of test sequences may be audio test sequences or video test sequences, and each test sequence may have an identifier (for example, a number), in this case, the test board may store comparison data corresponding to each test sequence in advance, and the comparison data corresponding to the test sequence may have an identifier (for example, a number) corresponding to the test sequence.

In the embodiment of the invention, the display image or the audio frequency of the test sequence is the same as the display image or the audio frequency of the comparison data corresponding to the test sequence. For example, when a video test is performed, if the display image corresponding to the test sequence is a circle, the display image corresponding to the contrast data is also the same circle.
In the embodiment of the present invention, the test board may be provided with an interface, and the interface is configured to capture port data and compare the port data with comparison data. Thus, the test board may generate port data after receiving the test sequence sent by the test control box, and the interface captures the port data, and determines whether the input port of the test board is normal or not according to the port data and the comparison data corresponding to the test sequence stored in the test board in advance.
Optionally, in the embodiment of the present invention, when the port of the test board is an input port, the test board may further send the test result to the test computer.
Specifically, the test result can be forwarded to the test computer through the test control box. The test result may be that the input port is normal, or that the input port is not normal. For example, 1 may be used to indicate that the input port is normal, and 0 may be used to indicate that the input port is not normal, so that the bytes occupied by the data sent by the test board to the test computer may be small.
Therefore, the test board in the embodiment of the present invention may receive the test sequence sent by the test control box after starting the kernel and completing initialization, and generate port data, and the test board may further compare the port data with the pre-stored comparison data, so as to determine whether the input port of the test board is working normally. In the embodiment of the invention, after the test single board starts the kernel and completes initialization, the hardware of the corresponding port can normally work, at this time, the test program can be started, and whether the test single board normally works can be judged without waiting for the test single board to stably output the display result, so that the time required by the test can be reduced, and the test efficiency is improved.
When the port is an output port, the testing method 100 is executed by a testing computer. At this time, the port data generated by the test board according to the test sequence may be acquired as follows: and receiving the port data forwarded by the test control box, wherein the port data is generated by the test single board according to the pre-stored test sequence and is sent to the test control box.
Here, the test sequence is pre-stored in the test board, and the comparison data corresponding to the test sequence is pre-stored in the test computer. For example, the test sequence may be stored in a storage area (e.g., a flash memory) of the test control box before the test board leaves a factory, the comparison data may be stored in a storage area of the test computer before the test computer leaves a factory, or the comparison data may be written in the storage area of the test computer in advance. Similarly, the test board may store a plurality of test sequences in advance, the test sequences may be audio test sequences or video test sequences, and each test sequence may have an identifier (for example, a number), the test computer may store comparison data corresponding to each test sequence in advance, and the comparison data corresponding to the test sequences may have identifiers (for example, numbers) corresponding to the test sequences.
Therefore, the test computer can receive the port data forwarded by the test control box, the port data is generated by the test single board according to the pre-stored test sequence and is sent to the test control box, and the test computer determines whether the output port of the test single board is normal or not by the port data and the comparison data which is pre-stored in the test computer and corresponds to the test sequence.
Therefore, the test computer in the embodiment of the present invention may receive the port data generated by the test control box forwarding the test board according to the pre-stored test sequence after the test board starts the kernel and completes initialization, and may compare the port data with the pre-stored comparison data, so as to determine whether the output port of the test board is working normally. In the embodiment of the invention, after the test single board starts the kernel and completes initialization, the hardware of the corresponding port can normally work, at this time, the test program can be started, and whether the test single board normally works can be judged without waiting for the test single board to stably output the display result, so that the time required by the test can be reduced, and the test efficiency is improved.
It should be noted that, in the embodiment of the present invention, the test of the input port and the test of the output port are independent from each other, that is, the test of the input port and the test of the output port may be performed simultaneously, or the test of the input port may be performed first and then the test of the output port may be performed, or the test of the output port may be performed first and then the test of the input port is performed, which is not limited in the embodiment of the present invention.
Optionally, the testing method 100 may be configured to perform a video test on the input or output port, where the port data may be a part of port data corresponding to a contrast area, and the contrast data may be a part of contrast data corresponding to the contrast area, where the contrast area is a part of area in a display area of the test board.
Specifically, when the input port data and the comparison data are video data, a partial area may be determined in the display area of the test board, and the partial area may be used as the comparison area. Then acquiring partial port data of the port data corresponding to the contrast area; and acquiring partial contrast data corresponding to the contrast data in the contrast area, wherein the port data can be partial port data, and the contrast data can be partial contrast data.
For example, if the resolution of the display of the test board is 1920 × 1080, the contrast area may be a 25 × 25 area in the display, which may be located anywhere on the display, such as the middle portion, the upper left corner, or the lower right corner.
In the embodiment of the invention, the test result of the port of the test single board is determined by comparing part of the port data with part of the comparison data, so that the compared data amount can be reduced, the test result can be obtained more quickly, and the test efficiency is further improved.
Optionally, the comparing the port data with pre-stored comparison data to determine a test result of the port of the test board includes:
determining a difference between the port data and the contrast data;
and determining the test result of the port of the test single board according to the difference value of the port data and the comparison data.
Specifically, in this embodiment of the present invention, if the absolute value of the difference between the port data and the comparison data is greater than a first threshold, the test result of the port indicates that the port is abnormal, and the first threshold is a positive number greater than zero; if the absolute value of the difference between the port data and the comparison data is less than or equal to the first threshold, the test result of the port indicates that the port is normal.
In the embodiment of the present invention, the difference between the port data and the comparison data is within a certain range (for example, the first threshold), and the port may be considered to be normal. The first threshold value can be preset in the test single board and the test computer.
When a video test is performed, Red Green Blue (RGB) values of port data and comparison data may be compared, and an input port may be normal when an absolute value of a difference between RGB values of the port data and the comparison data is set to be less than or equal to a first threshold, and the input port may be abnormal when the absolute value of the difference between RGB values of the port data and the comparison data is greater than the first threshold. In particular, each component of the RGB values may be compared to a first threshold.
For example, the first threshold value pre-stored in the test board or the test computer is (10,10, 10). When the RGB value of the port data corresponding to the pixel point in the contrast region is (90,85,87), the RGB value of the contrast data corresponding to the pixel point in the contrast region is (85,85, 85). Thus, the absolute value of the difference between the port data and the comparison data is (5,0, 2). At this time, the port of the test board may be considered normal. When the RGB values of the port data corresponding to the pixel points in the contrast region are (102,74,83), the RGB values of the contrast data corresponding to the pixel points in the contrast region are (85,85, 85). Thus, the absolute value of the difference between the port data and the comparison data is (17, | -11|, | -2 |). At this time, the port of the test board may be considered to be abnormal.
Optionally, in this embodiment of the present invention, comparing the port data with pre-stored comparison data to determine a test result of the port of the test board may include: determining a ratio of the port data and the contrast data; and determining the test result of the port of the test single board according to the ratio of the port data and the comparison data.
Specifically, if the absolute value of the difference between the ratio of the port data and the comparison data and 1 is greater than a second threshold, the test result of the port indicates that the port is abnormal, and the second threshold is a positive number greater than zero; and if the absolute value of the difference value between the ratio of the port data and the comparison data and 1 is less than or equal to the second threshold value, the test result of the port indicates that the port is normal.
In the embodiment of the present invention, the port may be considered to be normal if the ratio existing between the port data and the comparison data is within a certain range, for example, the difference between the ratio and 1 is within a second threshold range. The second threshold value can be preset in the test single board and the test computer.
For example, the second threshold value pre-stored in the test board or the test computer is (0.1,0.1, 0.1). When the RGB value of the port data corresponding to the pixel point in the contrast region is (90,85,87), the RGB value of the contrast data corresponding to the pixel point in the contrast region is (85,85, 85). Thus, the absolute value of the difference between the ratio of the port data and the comparison data and 1 is (5/85,0, 2/85). At this time, the port of the test board may be considered normal. When the RGB values of the port data corresponding to the pixel points in the contrast region are (102,74,83), the RGB values of the contrast data corresponding to the pixel points in the contrast region are (85,85, 85). Thus, the absolute value of the difference between the ratio of the port data and the comparison data and 1 is (17/85, | 11/85|, | -2/85 |). At this time, the port of the test board may be considered to be abnormal.
