OCMock is an Objective-C implementation of mock objects.

The OCMock framework provides the ability of using mock objects in Objective-C applications. Some of the functionality in the framework is:

  • Create fail-fast and nice mocks.
  • Ability to stub and return predetermined values.
  • Mock instance and class methods.
  • Mock protocols and notification observers.
  • Partial mocks to stand in for a real object.
  • Forward messages to other objects.
