NAME

Test::PostgreSQL - PostgreSQL runner for tests

SYNOPSIS

  use DBI;
  use Test::PostgreSQL;
  use Test::More;

  # optionally
  # (if not already set at shell):
  #
  # $ENV{POSTGRES_HOME} = '/path/to/my/pgsql/installation';

  my $pgsql = Test::PostgreSQL->new()
      or plan skip_all => $Test::PostgreSQL::errstr;

  plan tests => XXX;

  my $dbh = DBI->connect($pgsql->dsn);

DESCRIPTION

Test::PostgreSQL automatically setups a PostgreSQL instance in a temporary directory, and destroys it when the perl script exits.

This module is a fork of Test::postgresql, which was abandoned by its author several years ago.

FUNCTIONS

new

Create and run a PostgreSQL instance. The instance is terminated when the returned object is being DESTROYed. If required programs (initdb and postmaster) were not found, the function returns undef and sets appropriate message to $Test::PostgreSQL::errstr.

base_dir

Returns directory under which the PostgreSQL instance is being created. The property can be set as a parameter of the new function, in which case the directory will not be removed at exit.

initdb

postmaster

Path to initdb and postmaster which are part of the PostgreSQL distribution. If not set, the programs are automatically searched by looking up $PATH and other prefixed directories.

initdb_args

postmaster_args

Arguments passed to initdb and postmaster. Following example adds --encoding=utf8 option to initdb_args.

  my $pgsql = Test::PostgreSQL->new(
      initdb_args
          => $Test::PostgreSQL::Defaults{initdb_args} . ' --encoding=utf8'
  ) or plan skip_all => $Test::PostgreSQL::errstr;

dsn

Builds and returns dsn by using given parameters (if any). Default username is 'postgres', and dbname is 'test' (an empty database).

uri

Builds and returns a connection URI using the given parameters (if any). See URI::db for details about the format.

Default username is 'postgres', and dbname is 'test' (an empty database).

pid

Returns process id of PostgreSQL (or undef if not running).

port

Returns TCP port number on which postmaster is accepting connections (or undef if not running).

start

Starts postmaster.

stop

Stops postmaster.

setup

Setups the PostgreSQL instance.

ENVIRONMENT

POSTGRES_HOME

If your postgres installation is not located in a well known path, or you have many versions installed and want to run your tests against particular one, set this environment variable to the desired path. For example:

 export POSTGRES_HOME='/usr/local/pgsql94beta'

This is the same idea and variable name which is used by the installer of DBD::Pg.
