The present disclosure provides an array substrate, a testing method, a display panel and a display apparatus. The array substrate includes: multiple gate wires and data wires intersecting with each other to divide multiple sub-pixel regions, where the sub-pixels corresponding to each of the data wires form a column of the sub-pixels, and M neighboring columns of the sub-pixels form a sub-pixel group; multiple switch units, where a first end of each of the switch units is electrically connected to one of the data wires; and multiple testing ends, each of which is electrically connected to second ends of the switch units. In such configuration, at least two switch units are electrically connected to the data wires corresponding to ith columns of the sub-pixels in at least two alternately arranged sub-pixel groups, respectively. Accordingly, impacts to voltage of common electrodes may be avoided and testing effect may be improved.
