Warning: Ambiguous first argument; make sure


#1

Hello,

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?

Thanks

Quoting Heinz S. removed_email_address@domain.invalid:

Does anyone know why or how to change it so it disappears?

IIRC, parentheses fix the warning. I.e.,

assert_match(/^[a-zA-Z0-9]+$/, user.username)

Why it is ambiguous I will leave to someone better in Ruby than I.

HTH,
Jeffrey
