Subliminal is a framework for integration testing:
Subliminal provides a familiar OCUnit/SenTest-like interface to Apple’s UIAutomation framework, with tests written entirely in Objective-C. Subliminal also provides a powerful mechanism for your tests to manipulate your application directly.
Write your tests in Objective-C, and run them from Xcode. See rich-text logs and screenshots in Instruments. Use UIAutomation to simulate user interaction. Subliminal lets you use familiar tools, no dependencies required.
