[iOS] Unit Test Frameworks

Apple provide its default test framework XCTestCase, but it's hard to use it to test async / block /delegate / protocol methods.

Here are some open source tools which can help you do everything as you want:

• OCMockito - https://github.com/jonreid/OCMockito
  It's easy to mock any object, protocol can also be mocked, but can't handle the async methods.
• Expecta - https://github.com/specta/expecta
  It provides powerful matchers and easy to use.
• Aspects - https://github.com/steipete/Aspects
  Just like the name, you can do something before or after the methods or replace the methods' implementation.
• Kiwi - https://github.com/kiwi-bdd/Kiwi
  It's very very powful to do asynchronous testing, stub methods to capture any methods' parameter, protocol mock and handle any you want to do.
