We have an application developed using Zend Framework preview version 0.7. Now I would like to write unit test its controllers / logic files.
The logic mostly deals with the database and for database I am using my own wrapper.
Did anybody try unit testing an application on top of Zend Framework version 0.7 ?
I was the Project Manager of Zend Framework 0.7. That Preview Release you mention was made in January 2007 -- about 26 months ago! It was a very early release, and ZF has been refactored many times since then.
You really should never have employed such an early, raw version of ZF in a project that would last this long.
You should upgrade to ZF 1.6 or newer, and use the unit testing component provided.
Regarding your comment, see http://framework.zend.com/manual/en/zend.controller.migration.html for information on upgrading from older releases. This only covers Zend_Controller, not other components of ZF. This is the only guide I'm aware of. There's no specific "0.7 to 1.7" guide.
Good luck.
