=head1 NAME
-DBICTest - Library to be used by DBIx::Class test scripts.
+DBICTest - Library to be used by DBIx::Class test scripts
=head1 SYNOPSIS
- use lib qw(t/lib);
- use DBICTest;
+ BEGIN { do "./t/lib/ANFANG.pm" or die ( $@ || $! ) }
+
+ use warnings;
+ use strict;
use Test::More;
+ use DBICTest;
my $schema = DBICTest->init_schema();
This module provides the basic utilities to write tests against
DBIx::Class.
+=head1 EXPORTS
+
+The module does not export anything by default, nor provides individual
+function exports in the conventional sense. Instead the following tags are
+recognized:
+
+=head2 :DiffSQL
+
+Same as C<use SQL::Abstract::Test
+qw(L<is_same_sql_bind|SQL::Abstract::Test/is_same_sql_bind>
+L<is_same_sql|SQL::Abstract::Test/is_same_sql>
+L<is_same_bind|SQL::Abstract::Test/is_same_bind>)>
+
+=head2 :GlobalLock
+
+Some tests are very time sensitive and need to run on their own, without
+being disturbed by anything else grabbing CPU or disk IO. Hence why everything
+using C<DBICTest> grabs a shared lock, and the few tests that request a
+C<:GlobalLock> will ask for an exclusive one and block until they can get it.
+
=head1 METHODS
=head2 init_schema
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.
+This method will call L<deploy_schema()|/deploy_schema> by default, unless the
+C<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.
+Also, by default, this method will call L<populate_schema()|/populate_schema>
+by default, unless the C<no_deploy> or C<no_populate> flags are set.
