A UV Test Grid is a basic image made exclusively to test how the UVs of a mesh work. It’s an image with a grid; when it’s projected on the 3D model, it provides you with a lot of information. The size of the grid will show you which parts of your object are using more space from the texture (the smaller the grid, the more resolution the texture will have in that area).
