CUT is a unit-testing framework for C, C++, and Objective-C. Unlike other unit testing tools, CUT doesn't strive to be an SUnit clone. It automates a lot of the drudge work often encountered when using other unit testing packages for the C family of programming languages. CUT may also be used to unit-test assembly language software in some circumstances.
retainCounter is an application that converts a simple [object release] into a NSLog(@"object retainCount: %i",[object retainCount]); [object release]; command. This is sometimes useful if developers wish to know the current count of an object before it is released, which makes it easier to detect memory leaks.
