Test asynchronous Swift code by using the Swift Testing framework to write deterministic tests for modern async/await functions. This ensures network requests and background tasks complete successfully and handle errors correctly.

The best way to test Swift APIs with completion handlers is using the `confirmation` pattern. This allows you to gracefully test legacy callback-based APIs and verify event confirmations deterministically within the Swift Testing framework.

Swift Testing handles concurrency by executing tests in parallel by default. This framework provides patterns to manage shared state safely and enables deterministic testing of concurrent operations without race conditions.

To migrate asynchronous tests from XCTest to Swift Testing, you transition to the framework's native async/await support and `confirmation` pattern for callbacks. This enables deterministic testing of concurrent operations and event confirmations without XCTest expectations.

Yes, Swift Testing supports timeout control for async operations. This Skill covers timeout control patterns alongside @MainActor isolation, enabling you to validate that concurrent operations and event confirmations complete within expected timeframes.

Yes, you can test @MainActor isolated functions in Swift using the Swift Testing framework. It provides specific patterns to handle @MainActor isolation correctly while testing asynchronous code and managing concurrency.
