When dumping or populating fixture sets, you use this to set which sets.
Str or Array of String. Defaults to all_tables.
Please note that if you manually describe your sets as in the above example,
you dont automatically get the all_tables set, which is a fixture set of all
database information and not all the sets.
We automatically create the all_tables fixture set description file for you when
you prepare a new migration of the schema. You can use this set for early
testing but I recommend you study DBIx::Class::Fixtures and learn the set
configuration rules, and create limited fixture sets for given purposes, rather
than just dump / populate everything, since that is like to get big pretty fast
My recommendation is to create a core seed set, of default database values,
such as role types, default users, lists of countries, etc. and then create a
demo or dev set that contains extra information useful to populate a
database so that you can run test cases and develop against.
