[TxMt] Cocoa development with Textmate no Xcode

Greetings,

This is slightly off topic but I'm hoping some of the TextMate-Cocoa people here could help me.

I'm learning Cocoa programming and I'm not interested in using Xcode for my development. I prefer using Clang, Rake, Textmate, and Interface Builder. I know Allan and company development Textmate using Cmake instead of Xcode. I'm wondering how to run unit tests this way. Every OCUnit app tutorial I see assumes you are using Xcode. Anyone know how to set up unit tests manually via the command line? Once I see how it is done I can set up a Rake target/tasks to handle it for me.

Any other advice when developing Cocoa apps without Xcode?

Thanks in advance, Jason C
