NAME

Test::mysqld - mysqld runner for tests

SYNOPSIS

            

              
              
use DBI;
use Test::mysqld;
use Test::More;
my $mysqld = Test::mysqld->new(
  my_cnf => {
    'skip-networking' => '', # no TCP socket
  }
) or plan skip_all => $Test::mysqld::errstr;
plan tests => XXX;
my $dbh = DBI->connect(
  $mysqld->dsn(dbname => 'test'),
);
# start_mysqlds is faster than calling Test::mysqld->new twice
my @mysqlds = Test::mysqld->start_mysqlds(
  2,
  my_cnf => {
    'skip-networking' => '', # no TCP socket
  }
) or plan skip_all => $Test::mysqld::errstr;
Test::mysqlds->stop_mysqlds(@mysqlds);
            
          

DESCRIPTION

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

FUNCTIONS

new

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

base_dir

Returns directory under which the mysqld 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.

copy_data_from

If specified, uses a copy of the specified directory as the data directory of MySQL. "Mysql" database (which is used to store administrative information) is automatically created if necessary by invoking mysql_install_db.

my_cnf

A hash containing the list of name=value pairs to be written into my.cnf. The property can be set as a parameter of the new function.

mysql_install_db

mysqld

Path to mysql_install_db script or mysqld program bundled to the mysqld distribution. If not set, the program is automatically search by looking up $PATH and other prefixed directories.

dsn

Builds and returns dsn by using given parameters (if any). Default username depends on a server version and a socket family. Default dbname is 'test'.

pid

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

start

Starts mysqld.

stop

Stops mysqld.

setup

Setups the mysqld instance.

read_log

Returns the contents of the mysqld log file.

start_mysqlds

Create and run some mysqld instances, and return a list of Test::mysqld.

stop_mysqlds

Stop some mysqld instances.
