Abstract: An array substrate and a testing method thereof are provided. The array substrate includes a plurality of clock signal lines and a plurality of testing terminals. As at least two of the plurality of clock signal lines may be connected to a same testing terminal, as compared with the arrangement of the related art in which one clock signal line is connected to one testing terminal, the array substrates provided by the embodiments of the present disclosure only need to have less testing terminals, and correspondingly, the testing device that is connected to the testing terminals of the array substrate provided by the embodiments of the present disclosure may contain less pins. Therefore, the testing device can have a relatively low production cost and a relatively small volume.
