=head1 NAME
DBIx::Class::Test::SQLite - Base class for running Class::DBI tests against DBIx::Class compat layer, shamelessly ripped from Class::DBI::Test::SQLite
=head1 SYNOPSIS
  use base 'DBIx::Class::Test::SQLite';
  __PACKAGE__->set_table('test');
  __PACKAGE__->columns(All => qw/id name film salary/);
  sub create_sql {
      return q{
          id     INTEGER PRIMARY KEY,
          name   CHAR(40),
          film   VARCHAR(255),
          salary INT
      }
  }
=head1 DESCRIPTION
This provides a simple base class for DBIx::Class::CDBICompat tests using
SQLite.  Each class for the test should inherit from this, provide a
create_sql() method which returns a string representing the SQL used to
create the table for the class, and then call set_table() to create the
table, and tie it to the class.

# adding implicit search criteria to the iterator will alter the test

# change too much
BEGIN { $ENV{DBIC_SHUFFLE_UNORDERED_RESULTSETS} = 0 }
use lib 't/lib';
use DBICTest;
BEGIN {
  eval { require DBIx::Class::CDBICompat }
    or plan skip_all => 'Class::DBI required for this test';
}
use base qw/DBIx::Class/;
__PACKAGE__->load_components(qw/CDBICompat Core DB/);
my $DB = DBICTest->_sqlite_dbfilename;
my @DSN = ("dbi:SQLite:dbname=$DB", '', '', { AutoCommit => 1, RaiseError => 1 });
__PACKAGE__->connection(@DSN);
__PACKAGE__->set_sql(_table_pragma => 'PRAGMA table_info(__TABLE__)');
__PACKAGE__->set_sql(_create_me    => 'CREATE TABLE __TABLE__ (%s)');
__PACKAGE__->storage->dbh->do("PRAGMA synchronous = OFF");
=head1 METHODS
=head2 set_table
    __PACKAGE__->set_table('test');
This combines creating the table with the normal DBIx::Class table()
call.
=cut
sub set_table {
    my ($class, $table) = @_;
    $class->table($table);
    $class->_create_test_table;
}
sub _create_test_table {
    my $class = shift;
    my @vals  = $class->sql__table_pragma->select_row;
    $class->sql__create_me($class->create_sql)->execute unless @vals;
}
=head2 create_sql
This is an abstract method you must override.
  sub create_sql {
      return q{
          id     INTEGER PRIMARY KEY,
          name   CHAR(40),
          film   VARCHAR(255),
          salary INT
      }
  }
This should return, as a text string, the schema for the table represented
by this class.
