Framework-Free Dependency Injection
summary
Claims manual DI replaces heavy frameworks like Dagger for most unit-testing needs and ships a concrete recipe: define an interface, inject via constructor, provide a production implementation and pass a fake in tests. Examples: a Kotlin humanTimeHelper and a credit‑card presenter/viewmodel that moves SharedPreferences behind a LastCardStorage. Result: repeatable, JVM‑only unit tests, no build or runtime penalty, at the cost of extra constructor boilerplate and more interfaces to manage.
