Questions tagged [ocmockito]

OCMockito is an Objective-C implementation of Mockito, supporting creation, verification and stubbing of mock objects.

Key differences from other mocking frameworks:

  • Mock objects are always "nice," recording their calls instead of throwing exceptions about unspecified invocations. This makes tests less fragile.
  • No expect-run-verify, making tests more readable. Mock objects record their calls, then you verify the methods you want.
  • Verification failures are reported as unit test failures, identifying specific lines instead of throwing exceptions. This makes it easier to identify failures. (It also keeps the pre-iOS 5 Simulator from crashing.)
