[TYPO3-dev] Another PHPUnit in TYPO3 6.1.7

[Thomas Hucke]

Hi all,

I´m trying to develop some tests for my extension but every test I create 
fires the following error when it´s running:
"Fatal error: Call to a member function close() on a non-object in 
N:\xampp\htdocs\testsite61\typo3\sysext\core\Classes\Database\DatabaseConnection.php 
on line 1611"

I tried the tests included in the sysext extbase (e.g. FrontendUserTest). 
There the error also appears.

Any idea?
Thanks
Thomas
