This is a ever so slightly modified fork of OCMock that allows for building inside another project in stead of building it as a framework.
OCMock is an Objective-C implementation of mock objects. Github is used to store and manage the source code. For documentation and support please visit ocmock.org.
If you are unfamiliar with the concept of mock objects, please visit mockobjects.com. It has more detail about this approach to testing software.
