No, you currently need to do:

insert into test (name) values ('test#1');

The SQL standard does have a feature like that, the <contextually typed
value specification>. I have created a ticket:
http://tracker.firebirdsql.org /browse/CORE-5449. For insert, the SQL
standard says:

"An <insert columns and source> that specifies DEFAULT VALUES is
implicitly replaced by an <insert columns and source> that specifies a
<contextually typed table value constructor> of the form VALUES
(DEFAULT, DEFAULT, ..., DEFAULT) where the number of instances of
“DEFAULT” equal to the number of columns of T."

If you follow the definition of insert (and update, merge, etc), you'll
see that DEFAULT is a contextual value similar to CURRENT_USER etc, and
means "use the default, or null if there is no default".
