Ok guys you need to get this file:

https://raw.githubusercontent.com/aceat64/EasyBitcoin-PHP/master/easybitcoin.php

Save it to a folder. In the same folder save the code in a file testnet.php:

require_once('easybitcoin.php');

$rpcuser = 'x';
$rpcpass = 'y';
$port = '35001';
$rpcip = '127.0.0.1';

//$argv[0] name of file
//$argv[1]  address to send
//$argv[2]  amount to send
//$argv[3]  loop times

echo 'Begin';
echo '

';
echo '

';
$bitcoin = new Bitcoin($rpcuser,$rpcpass,$rpcip,$port);
$bitcoin->getaddressesbyaccount();
$address=null;

if(isset($bitcoin->response["result"][0]))
$address=$bitcoin->response["result"][0];

if(isset($argv[1]))
$address = $argv[1];
else if(isset($address))
$address = $bitcoin;
else{
echo "No address, no send"; die;
}

if(isset($argv[2]))
$amount = $argv[2];
else
$amount = 2;

if(isset($argv[3]))
$loop_times = $argv[3];
else
$loop_times = 1;

echo 'Sending';
echo '

';
$tx = array();

for($i=0;$i<$loop_times;$i++)
{
$bitcoin->sendtoaddress($address,$amount);
array_push( $tx,$bitcoin->response["result"] );
}

echo 'Sent';
echo '

';
echo 'TX:';
echo '

';
var_dump($tx);
echo '

';
echo '

';
echo 'End';
?>

Then you can open shell and run: php testnet.php

You need PHP installed and configured in your OS.
I did this just now, not sure gonna work.
