+
+=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.

+
+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.
