Cocoa/ObjC Unit Testing?

I'm trying to use this SenTestingKit.framework to write unit tests. I created a new target called Test, have a test in there subclassing SenTestCase, created a method like "-(void) testSomething { STAssertTrue(false,@"blah"); }, and the target builds without a hitch. Can someone figure out some step I missed? Thanks.

 

Figured it out... the testing target I was creating was a Testing Framework when it should have been (obviously) the Unit Test Bundle. Works now.
