Test::PostgreSQL::Docker - A Postgresql mock server for testing perl programs

SYNOPSIS

use Test::More;
use Test::PostgreSQL::Docker;

# 1. create a instance of Test::PostgreSQL::Docker with postgres:12-alpine image
my $server = Test::PostgreSQL::Docker->new(tag => '12-alpine');

# 2. create/run a container
$server->run();

# 3. puke initialization data into postgresql on a container
$server->run_psql_scripts("/path/to/fixture.sql");

# 4. get a Database Handler(a DBI::db object) from mock server object
my $dbh = $server->dbh();

# (or call steps of 2 to 4 as method-chain)
my $dbh = $server->run->run_psql_scripts("/path/to/fixture.sql")->dbh;

# 5. query to database
my $sth = $dbh->prepare("SELECT * FROM Users WHERE id=?");
$sth->execute(1);

# 6. put your own test code below
my $row $sth->fetchrow_hashref();
is $row->{name}, "ytnobody";
