Swift Testing
Overview
Swift Testing is Apple's modern testing framework introduced at WWDC 2024. It uses Swift macros (@Test, #expect) instead of naming conventions, runs tests in parallel by default, and integrates seamlessly with Swift concurrency.
Core principle: Tests should be fast, reliable, and expressive. The fastest tests run without launching your app or simulator.
The Speed Hierarchy
Tests run at dramatically different speeds depending on how they're configured:
| Configuration | Typical Time | Use Case |
|---|---|---|
swift test (Package) |
~0.1s | Pure logic, models, algorithms |
| Host Application: None | ~3s | Framework code, no UI dependencies |
| Bypass app launch | ~6s | App target but skip initialization |
| Full app launch | 20-60s | UI tests, integration tests |
