=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,
    storage_type=>'::DBI::Replicated',
    storage_type_args=>{
    	balancer_type=>'DBIx::Class::Storage::DBI::Replicated::Balancer::Random'
    },
  );

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.

    }
    return $schema;
}

=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.

        return $schema->deploy();
    } 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.
