Wooden field camera will do fine as a test bed.
Resolution is the least important factor to me unless its inadequate, and oh yea, dof plus stopping down at middle apertures homogenize many of the lens characteristics.
The test the OP describes is not expected to differentiate between 60 lpm vs. 40 lpm, but answer the question "is the lens adequate and functional".
