Mocking with Swift

on YouTube ↗28m

" summary

Explains why mocking in Swift is awkward, shows concrete refactors: add dependency injection and program to a protocol so NotificationCenter can be swapped, build a hand‑rolled mock that records calls then demonstrate its limits, and then replace it with Sorcery generating AutoMockable types so tests use generated mocks instead of 30–100 lines of boilerplate; shows Quick and Nimble are used and reports this codegen is used in production on the Jinyu Scan codebase.
