SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps teams modernize existing Swift test suites by converting older XCTest patterns into clearer, more maintainable Swift Testing code without losing behavior.

Core Features & Use Cases

  • XCTest to Swift Testing migration: Replace XCTestCase-based suites, assertions, skips, expectations, and attachments with modern Swift Testing equivalents.
  • Incremental test modernization: Update one test class or file at a time, supporting mixed XCTest and Swift Testing code during transition.
  • Behavior-preserving refactors: Handle setup and teardown, async flows, known failures, and shared state while keeping test intent intact.
  • Use case: A Swift iOS app with a large legacy XCTest suite can be converted file by file into Swift Testing with better structure and readability.

Quick Start

Ask me to modernize the existing XCTest tests in a Swift file to Swift Testing and I will rewrite them using the appropriate modern patterns.

FAQPage Schema
How do I migrate XCTest assertions and expectations to Swift Testing?

Swift Testing migration supports incremental modernization, allowing you to convert XCTest files one at a time while maintaining mixed test environments during the transition without breaking existing behavior.

Can I migrate XCTest setup and teardown methods to Swift Testing?

Yes, XCTest setup and teardown methods are migrated to Swift Testing by translating them into suite structures and shared-state control mechanisms that maintain the same initialization and cleanup behavior.

How do you handle XCTest skips and known issues when modernizing tests?

Modernizing tests handles XCTest skips and known issues by converting them into Swift Testing traits and known failure handling, ensuring test behavior remains intact while meeting modern framework requirements.

What is the best way to convert an iOS XCTest suite to Swift Testing?

The best way to convert an iOS XCTest suite is incremental modernization, updating one test class or file at a time to apply modern suite structures, async patterns, and attachment handling without losing behavior.

How does async test migration work when moving from XCTest to Swift Testing?

Async test migration works by replacing XCTest asynchronous flows with Swift Testing native async patterns, ensuring that modern test suites handle asynchronous operations and shared-state control correctly.
