An automatic test system suitable for testing a server comprises a storage device, a computing device, and a sensing device. The storage device stores an automatic test script. The sensing device collects a plurality of test results of the server. The automatic test script comprises a parameter configuration module, a data processing module, and a core logic module. The parameter configuration module provides a plurality of configuration parameters associated with a server test procedure. The data processing module comprises a data recording sub-module and a data sorting sub-module, while the former receives an output data set from the server test procedure, and the latter generates a test report according to the output data set and the configuration parameters. The core logic module comprises a plurality of instruction sets for controlling the server test procedure through a data exchange interface.
