### Design for Test

The design for Test(DFT) domain consists of a list of constraints which defines certain rules that need to be satisfied for PCB test process to run smoothly.
Outline, Spacing, Probe, Mask and silkscreen, are some examples of categories of checks that fall under design for test domain constraints.
The DFT constraints are defined on DFT constraint sets which can be associated with test layers. The constraints need to be turned on to get them evaluated in batch or online operations.
