  20 =head1 DESCRIPTION
  21
  22 This module provides the basic utilities to write tests against
  23 DBIx::Class.
  24
  25 =head1 METHODS

  27 =head2 init_schema
  28
  29   my $schema = DBICTest->init_schema(
  30     no_deploy=>1,
  31     no_populate=>1,
  32     storage_type=>'::DBI::Replicated',
  33     storage_type_args=>{
  34         balancer_type=>'DBIx::Class::Storage::DBI::Replicated::Balancer::Random'
  35     },
  36   );
  37
  38 This method removes the test SQLite database in t/var/DBIxClass.db
  39 and then creates a new, empty database.
  40
  41 This method will call deploy_schema() by default, unless the
  42 no_deploy flag is set.
  43
  44 Also, by default, this method will call populate_schema() by
  45 default, unless the no_deploy or no_populate flags are set.

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

 149 the tables with test data.
