mockolo - Efficient Mock Generator for Swift

•    Swift

Mockolo is an efficient mock generator for Swift. Swift doesn't provide mocking support, and Mockolo provides a fast and easy way to autogenerate mock objects that can be tested in your code. One of the main objectives of Mockolo is fast performance. Unlike other frameworks, Mockolo provides highly performant and scalable generation of mocks via a lightweight commandline tool, so it can run as part of a linter or a build if one chooses to do so. Try Mockolo and enhance your project's test coverage in an effective, performant way. One of the main objectives of this project is high performance. There aren't many 3rd party tools that perform fast on a large codebase containing, for example, over 2M LoC or over 10K protocols. They take several hours and even with caching enabled take several minutes. Mockolo was built to make highly performant generation of mocks possible (in the magnitude of seconds) on such large codebase. It uses a minimal set of frameworks necessary (mentioned in the Used libraries section) to keep the code lean and efficient.

This is an addon plugin for the chai assertion library. It provides the most basic function spy ability and tests.
