Test method of set-top box and test system thereof

The invention relates to the set-top box field, especially to a test method of a set-top box and a test system thereof. The method comprises the following steps that: a configuration file is stored in a PC machine in advance, wherein the configuration file includes a plurality of control commands and each control command corresponds to one test item, and the PC machine generates a test interface including a plurality of test items; after a user selects a test item that needs to be tested on the test interface, the PC machine finds a selected control command in the configuration file according to the test item selected by the user and sends the selected control command to a set-top box; the set-top box tests a corresponding test item according to the selected control command; and after the test by the set-top box is completed, the result is generated into a log that is then stored in the set-top box; and meanwhile, the log is sent to the PC machine for storage. According to the invention, test interface software is developed on a PC machine and matched test execution software is developed on a set-top box; the software code scale is small; and besides, characteristics of simpleness, easiness of maintenance, easiness of operation and high portability are realized.
