SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill streamlines the migration of legacy XCTest code to the modern Swift Testing framework, ensuring behavior preservation and improving test readability.

Core Features & Use Cases

XCTest Migration: Convert XCTestCase classes, XCTAssert calls, and async patterns to their Swift Testing equivalents (@Test, #expect, async/await).
Behavior Preservation: Ensures that the core functionality and assertions of existing tests remain intact during the migration process.
Use Case: You have a large suite of tests written with XCTest and your project is adopting Swift Testing. Use this Skill to systematically convert your existing tests to the new framework with minimal risk of breaking existing coverage.

Quick Start

Migrate the provided XCTest file to Swift Testing, preserving all original assertions and behavior.

FAQPage Schema

How do I migrate XCTest to Swift Testing in an existing Xcode project?▼

Swift Testing handles asynchronous patterns by converting XCTest async expectations into native async/await syntax within @Test functions. This ensures behavior preservation for regression coverage while modernizing asynchronous tests.

Can I incrementally adopt Swift Testing without breaking my current XCTest suite?▼

No external dependencies are required for the migration. The Skill operates independently to refactor XCTest code into Apple's native Swift Testing framework, converting XCTAssert APIs and test cases into modern equivalents without additional package dependencies.

What is the best way to convert XCTestCase classes to Swift Testing functions?▼

The best way to convert XCTestCase classes is to transform them into @Test functions while replacing XCTAssert APIs with #expect and #require. This refactoring modernizes test readability and aligns with native Swift concurrency standards.

Does migrating XCTest to Swift Testing preserve existing assertions and behavior?▼

Yes, migrating XCTest to Swift Testing preserves existing assertions and behavior. The conversion process ensures that the core functionality of your tests remains intact, systematically replacing legacy APIs with @Test, #expect, and #require equivalents.
