Step 420: the test management system establishes network addressing codes corresponding to the test computers; specifically, the IP position coding module codes according to the unique identification information of the testing computer, wherein the coding mode is that after the identification information of a group of testing computers is captured, corresponding network addressing codes are generated, or after the identification information of all the testing computers is captured, corresponding network addressing codes are generated for each identification information one by one, each network addressing code is not repeated, the corresponding relation between the identification information of each testing computer and the network addressing codes is established in a coding file mode, the coding files are stored in a testing program database, the coding formats of the network addressing codes are automatically numbered in sequence by adopting 3 codes of a 16-system, and the coding files of each testing computer are stored in the testing program database.

Step 450: detecting the starting times of the test program by the test computer; specifically, the test computer is provided with a program counting module for detecting and recording the times of closing/opening the test program and generating counting codes for distinguishing the times of opening and closing the test program used by the test computer. For example, 1 code in 16 system is recorded to distinguish the number of times the test computer uses the test program. In this case, the count code may be 16 times.
Step 460: the testing computer generates corresponding product coding information after performing product testing; specifically, after a test computer is connected with a test program through a control module to detect a product, product test information is generated, and then the actuation of a serial number generation module is triggered, a serial number generation module in the serial number generation module generates serial numbers for the product, wherein the serial numbers are coded in a serial number mode, when a product is detected, the serial numbers are sequentially added, then a network addressing code of the test computer is captured by the serial number generation module, and further the network addressing code of the test computer, a counting code of the turn-off/turn-on times of the test program and the serial numbers corresponding to the product form complete product coding information, so that the product can trace back information such as the detected test computer and the turn-off/turn-on times of the test program through the product coding information.
Step 470: the testing computer stores/outputs product coding information corresponding to each product; specifically, the test computer outputs or stores product code information (or product classification information). For example, the product code information is stored in each product in the form of a product serial number, stored in a test management system, stored in another production management system, or printed in a report, so that the product code information (or product classification information) can be integrated into another platform and the production information can be summarized.
In another embodiment, step 460 further includes step 450, after the test computer detects the product through the control module, generating product test information and triggering the serial number generation module to actuate, where the program counting module generates a counting code for the number of times of closing/opening the test program, the serial number generation module generates a serial number code for the product, and the serial number generation module retrieves the network addressing code of the test computer, so as to combine the network addressing code of the test computer, the counting code for the number of times of closing/opening the test program, and the serial number code of the product into a complete product code information, and steps 450 and 460 may change the sequence according to the design requirements, but are not limited thereto.
