About MockingKit

MockingKit is a Swift-based mocking library that makes it easy to mock protocols and classes, for instance when unit testing or mocking not yet implemented functionality.

MockingKit lets you register function results, invoke functions and inspect calls.

MockingKit doesn't put any restrains on your code or require you to structure it in any way. You don't need any setup or configuration. Just create a mock and you're good to go.
