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.)

Is there a workaround for the lack of a verify method on Kiwi mocks?

I have a strong preference for a highly predictable Arrange Act Assert format for unit tests. Because Kiwi doesn't have an explicit verify statement for mocks, it forces a different pattern, something like: // Arrange Thing *mockThing =…

My MessageSerializer class has a method whose signature looks like this: - (Message *)deserialize:(const void *)buffer length:(NSUInteger)length; Can I use OCMockito to stub it? Where serializer is my mock serializer, the compiler approves of all…

I'm trying to mock an object that is passed to my SUT. When passed, the SUT registers the mock as observer for some properties. In SUT dealloc, it calls removeObserver on the mock. This was working just fine with OCMockito 0.23, but when updating to…

Is there an idiomatic Objective-C technique to make an init method return a stub implementation for testing?

I am writing a unit test for a class Foo, which has a collaborator, Bar. I want to use a manually-built stub implementation of Bar in Foo's test. If I were doing this in Java, I would give Foo a BarFactory collaborator and inject a MockBarFactory in…
