About

This class is a simple NSUserDefaults replacement that can be used in tests. It does not persist any changes, so that each test can start with precisely controlled defaults environment.

CCTestingUserDefaults *defaults = [[CCTestingUserDefaults alloc] init];
// …set up defaults as needed…
ClassThatUsesDefaults *tested = [[ClassThatUsesDefaults alloc] init];
[tested setDefaults:(id)defaults];
// …run tests…

So far the class only supports several of the NSUserDefaults methods, feel free to add more and send me a pull request.
