swift protocol di testing
What it does
- Writing Swift code that accesses file system, network, or external APIs
- Need to test error handling paths without triggering real failures
- Building modules that work across environments (app, test, SwiftUI preview)
- Designing testable architecture with Swift concurrency (actors, Sendable)
- Single Responsibility: Each protocol should handle one concern — don't create "god protocols" with many methods
- Sendable conformance: Required when protocols are used across actor boundaries
- Default parameters: Let production code use real implementations by default; only tests need to specify mocks
Requirements & configuration
- Need to test error handling paths without triggering real failures
- Default parameters: Let production code use real implementations by default; only tests need to specify mocks
- Over-engineering: if a type has no external dependencies, it doesn't need a protocol
- Building modules that need to work in app, test, and SwiftUI preview contexts
- Apps using Swift concurrency (actors, structured concurrency) that need testable architecture
