The default Storage trait which provides the ability to deploy to a SQLite database. It also sets some
%ENV and or configuration options that you can use to specify alternative database setup.
In addition to the documented %ENV settings, this Trait adds the following:
DBNAME
Defaults to ':memory:' to create an in memory database. Provide a string suitable for the
"dbname=XXX" part of your connect string. Typically this should be the path to a location on the
filesystem you want the datbase file to be stored.
Please note that this file will automatically be deleted unless you have specified to 'keep_db' in
the config or via the $ENV{KEEP_DB} setting.
Also note that if you specify a path that already exists, we will automatically add the option
'force_drop_table', on the assumption you are roundtripping tests to the same database file. This
way you can avoid having to specifically tell the system to delete the file each time.
