[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] With the continuous advancement of communication technology, products, especially terminal devices, are frequently upgraded. During this product upgrade process, AT command compatibility is crucial, directly impacting device stability and user experience. AT commands are widely used, often between terminal devices and controllers, between terminal devices, and between terminal devices and PCs. Therefore, AT command compatibility testing is necessary during terminal device upgrades.

[0004] However, existing AT command compatibility testing mostly relies on manual operations, requiring testers to manually write test scripts and compare the execution results of AT commands one by one. This is not only time-consuming and labor-intensive, but also prone to inaccurate test results due to human factors, resulting in problems such as heavy workload, low efficiency, and low accuracy.

[0005] Although some researchers have proposed using software platforms or automated testing modules to implement command testing, this type of testing is generally not specifically targeted at AT commands, and is generally implemented on a single device through line-by-line comparison, which is inefficient. Summary of the Invention

The command import module is used to import the predetermined AT command name, format, parameters, range, and expected results; The command parsing module is used to extract key information of the imported AT command and automatically parse and form an AT command set for query and setting according to the command format; The result comparison and display module is used to obtain the execution result and response time returned by the AT instruction set executed and parsed by the target terminal device, recorded by the tooling board, compare it with the expected result and execution time, determine whether there is a difference between the two, and display the execution result and comparison result; The tooling board includes a communication circuit, a communication interface and a control module. The communication circuit is used to communicate with the PC end, realize information interaction with the PC end, receive the AT command set of the PC end and send back the output results, response time and other records of the tested device.

[0031] The communication interface includes a plurality of interfaces, each of which is connected to a target terminal device; The control module is used to identify the target terminal devices connected to the communication interface and their number, send predetermined AT commands to all currently connected target terminal devices according to the parsed AT command set, and receive and record the execution results and response time returned by each target terminal device.

[0032] The solution provided in this embodiment, through the cooperation between the PC and the tooling board, automatically parses AT commands into AT command test sets, automatically identifies the number of target terminal devices (i.e., test devices), automatically executes tests on the AT commands corresponding to all target terminal devices, and automatically compares the results, thereby achieving multi-concurrent testing. It can simultaneously perform AT command compatibility tests on multiple target terminal devices (i.e., test devices), thereby improving test efficiency.

[0033] In this embodiment, the functions of each module on the PC side can be implemented through software or programs.

[0034] In this embodiment, the instruction import module is as follows: Figure 2 As shown, it is configured to import the predetermined AT command name, format, parameters, range and expected result, judge the format of the imported document, and if the document format meets the preset format, apply regular expressions to extract the AT command. The extracted content includes the configurable value, range and format, and is combined into a json file; If the document format is incorrect, an error message will be returned and the tester will be required to re-import the correct document; If no AT command is extracted, an error will be recorded and a prompt will be given that there is no valid command.

After executing the instruction several times (such as 3 times) in a row, if the communication interface has no response, it is determined that there is no tested device on the communication interface; when the communication interface has a response, the tooling board automatically records and counts it.
