CLI error after run unittest that connect to SQLServer

I have CLI error when run unittest with cakephp that connect to SQLServer. Unittest can work but when complete, CLI error dialog will appear.

I used XAMPP and PHP 5.5. I also installed Microsoft SQL Server Native Client and enabled extension

extension=php_sqlsrv_55_ts.dll 
extension=php_pdo_sqlsrv_55_ts.dll

who used to solve this problem?
