I'm getting this warning:
Warning: Ambiguous first argument; make sure.
in my unit test:
assert_match /^[a-zA-Z0-9]+$/, user.username
Does anyone know why or how to change it so it disappears?
IIRC, parentheses fix the warning. I.e.,
Why it is ambiguous I will leave to someone better in Ruby than I.
