Subliminal is an open-source framework for writing iOS integration tests. Subliminal provides a familiar OCUnit/SenTest-like interface on top of 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.
Subliminal is designed to be instantly familiar to users of OCUnit/SenTest. In Subliminal, subclasses of SLTest define tests as methods beginning with "test". At run-time, the SLTestController discovers and runs these tests. Here's what a sample SLTest implementation looks like:
In the body of those tests, you do some work and then make some assertions.
Your tests live inside your application, so you can also manipulate the application directly, using app hooks. App hooks are Objective-C methods defined by the application, made available to your tests--so you could have one test verify that your login UI works, while the rest of your tests use a programmatic interface.
