A drop ball test fixture includes a bracket, first stoppers and connecting components. The bracket has bearing surfaces for bearing edges of a panel and to position the panel in a direction parallel to the bearing surfaces. At least part of each of the first stoppers is located above corresponding one of the bearing surfaces. Each connecting component includes a guide rod, a guide groove and a second stopper. The guide groove is formed on corresponding one of the first stoppers. One end of each of the guide rod is connected to the bracket while the other end thereof passes through the guide groove. Connecting structures are provided at different heights of the guide rod, and the second stopper is matched with and connected to corresponding one of the connecting structures at different heights above the guide groove so as to stop the upward movement of the first stopper.
