Test Driven Development (TDD) by Controlling Dependencies
summary
Argues that using SOLID and a Clean/hexagonal architecture makes real TDD practical on iOS by isolating view, presenter, interactor and repository layers; shows unit tests that avoid network and Core Data by using in-memory Core Data store, hand-written mocks (overriding UILabel text) instead of heavy mocking frameworks, and tests protocol extensions for segues; notes Xcode UI tests are integration tests, not unit tests; demonstrates a view controller with 92 tests and reports full coverage; uses protocol extensions in Swift 2.
