=head1 NAME
DBICTest - Library to be used by DBIx::Class test scripts.
=head1 SYNOPSIS
use lib qw(t/lib);
use DBICTest;
use Test::More;
my $schema = DBICTest->init_schema();
=head1 DESCRIPTION
This module provides the basic utilities to write tests against
DBIx::Class.
=head1 METHODS
=head2 init_schema
my $schema = DBICTest->init_schema(
no_deploy=>1,
no_populate=>1,
);
This method removes the test SQLite database in t/var/DBIxClass.db
and then creates a new, empty database.
This method will call deploy_schema() by default, unless the
no_deploy flag is set.
Also, by default, this method will call populate_schema() by
default, unless the no_deploy or no_populate flags are set.

=head2 deploy_schema
DBICTest->deploy_schema( $schema );
This method does one of two things to the schema. It can either call
the experimental $schema->deploy() if the DBICTEST_SQLT_DEPLOY environment
variable is set, otherwise the default is to read in the t/lib/sqlite.sql
file and execute the SQL within. Either way you end up with a fresh set
of tables for testing.

} else {
open IN, "t/lib/sqlite.sql";
my $sql;
{ local $/ = undef; $sql = <IN>; }
close IN;
($schema->storage->dbh->do($_) || print "Error on SQL: $_\n") for split(/;\n/, $sql);
}
}
=head2 populate_schema
DBICTest->populate_schema( $schema );
After you deploy your schema you can use this method to populate
the tables with test data.
