Running a test, I ran into this error:
Zend_Session_Exception: Session must be started before any output has been sent to the browser; output started in /usr/share/php/PHPUnit/Util/Printer.php/173
In order to solve that, I added a line calling
ob_start() to my test bootstrap file.
However, there is a better way!!
Instead, add the following line:
Zend_Session::$_unitTestEnabled = true;
This works flawlessly.
