It appears they test at considerably less than infinity

EDIT: Their chart for the 45mm f/1.8 lens is really not indicative of performance across its focus range.

Imaging Resource's testing of the 3D variant shows the corners having a touch of softness when used wide-open with their own test chart. https://www.imaging-resource.com/reviews/zproducts/samsung45f18nx3d/zz_sampleindex.htm

Samsung's MTF chart shows that corners are also slightly soft at infinity. (they list the same chart for both types of the lens)

Lastly, my (non-3D) copy is noticeably soft when used near minimum focus distance. I have provided central crops using the lens with an NX500. Final image is with Samsung's 30mm f/2 lens for comparison.
