Abstract: A testing method of electronic devices, each of which includes a central processing unit (CPU) for running an operating system (OS), includes the following steps when testing one of the electronic devices. The specification of the CPU of the electronic device and the version of the OS run on the CPU are identified. A test script of the electronic device is searched from a script lookup table according to the specification of the CPU and the version of the OS. The script lookup table records a variety of test scripts related to the specification of a variety of CPUs of a variety of electronic devices in combination with the version of a variety of operating systems. The found test script is provided to a testing module. The electronic device is tested by the testing module according to the found test script.
