compiling the kernel, the driver and the network chip through a compiling server to compile an initial test system image file on the basis of an open source system;
customizing the initial test system image file, wherein the customizing operation comprises the following steps: selecting a tool chain for compiling according to the CPU model of the switch; deploying a corresponding driver according to a hardware architecture of the switch; compiling a software development kit of a network chip, and configuring an initialization configuration file for the software development kit to ensure that a network address is matched with actual hardware; modifying the serial port configuration file to grant the serial port the authority to log in the root directory; modifying the script file under the root directory to enable the script file to automatically start and download the test program; and setting a master control script which sequentially calls the test program to execute the overall test.
8. The system of claim 7, wherein the system installation unit comprises:
the network connection module is used for connecting the switch to a production line network through a management port in advance through the production line network;
and the system installation module is used for calling a system loading and unloading tool to install the production line test system stored in the appointed catalogue after the switch is started, and starting the switch from the production line test system after the switch is installed.
9. A terminal, comprising:
a processor;
a memory for storing instructions for execution by the processor;
wherein the processor is configured to perform the method of any one of claims 1-4.
10. A computer-readable storage medium, in which a computer program is stored which, when being executed by a processor, carries out the method according to any one of claims 1-4.
