What makes a good ‘Test Font’

What do you include or remove in a ‘test font’ for a prospective client ?

Depends on what you mean by test font.
Depends on what is agreed and what the client wants.

An agency asked me for a test font but I am not quite sure what it means.
Is it a full typeface with all the characters but with a special ‘test’ licence or is it a typeface with some characters missing ?
What would you recommend ?

I guess I need to ask the client what he needs but I wanted to have someone’s opinion before I act on it

Make sure the family name contains ‘BETA’ or ‘TEST’.
