NAME¶

Bio::Chado::Schema::Test - Library to be used by Bio::Chado::Schema test scripts.

SYNOPSIS¶

  use lib qw(t/lib);
  use Bio::Chado::Schema::Test;
  use Test::More;
  my $schema = Bio::Chado::Schema::Test->init_schema();

DESCRIPTION¶

This module provides the basic utilities to write tests against Bio::Chado::Schema.

METHODS¶

init_schema¶

  my $schema = Bio::Chado::Schema::Test->init_schema(
    deploy            => 1,
    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/BCS.db and then creates a new, empty database. This method will call deploy_schema() by default, unless the deploy flag is set to 0. This method will call populate_schema() if the populate argument is set to a true value.

has_custom_dsn¶

Returns true if the BCS_TEST_DSN environment variable is set.

deploy_schema¶

  Bio::Chado::Schema::Test->deploy_schema( $schema );

This method does one of two things to the schema. It can either call the experimental $schema-> deploy() if the BCSTEST_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.

populate_schema¶

  Bio::Chado::Schema::Test->populate_schema( $schema );

After you deploy your schema you can use this method to populate the tables with test data.
