DESCRIPTION

This module provides helpful a wrapper for testing the correctness of DBIx::Class::Schema::Versioned upgrade scripts. Currently only MySQL is supported.

METHODS

new

A standard Moose constructor. Takes no arguments. A temporary database of the appropriate type will be lazy built when needed.

run_sql

Runs some SQL commands on the database. Normally this will be the deployment script to set-up the database schema, or an upgrade script to modify the schema.

The commands can be in a file, file-handle, or be supplied in a scalar reference.

Returns any errors as a string, or an empty string if there where none.

describe_tables

Probes all tables in the database and returns a data structure describing the schema (columns and indexes) on each table. The structure is intended to be passed to is_deeply for comparison.

FIELDS

dsn

The database dsn string. It can be used to connect to the database.

dbh

The database dbh handle. It contains a connection to the database.

test_db

The test database. The details of it are dependent on the database specific subclass. For example in Test::DBIC::Versioned::MySQL it is an instance of Test::mysqld.
