SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps developers write, review, and improve Swift Testing code without relying on outdated XCTest patterns or overlooking concurrency, isolation, and test design issues.

Core Features & Use Cases

  • Modern Test Authoring: Create Swift 6.2-compatible tests using structs, the @Test macro, #expect, #require, parameterized tests, and current testing traits.
  • Comprehensive Test Review: Identify genuine problems involving assertions, dependency injection, parallel execution, async behavior, confirmations, actor isolation, networking mocks, and test structure.
  • XCTest Migration Guidance: Convert unit and integration tests from XCTest to Swift Testing while preserving UI tests in XCTest where required.
  • Use Case: Review a Swift macOS application’s test suite, replace inappropriate XCTest assertions with Swift Testing expectations, and improve tests that depend on asynchronous work or hidden global state.

Quick Start

Use the swift-testing-pro skill to review the Swift Testing code in my project and report prioritized issues with before-and-after fixes.

FAQPage Schema
How do I migrate XCTest unit tests to Swift Testing?

Migrate XCTest unit and integration tests to Swift Testing by converting classes to structs, adopting the @Test macro, and using #expect and #require, while preserving UI tests in XCTest where required.

What is the best way to test concurrent code in Swift 6.2?

Test concurrent code in Swift 6.2 by writing tests that enforce actor isolation, handle asynchronous behavior safely, and support parallel execution using modern Swift Testing APIs and test traits.

How do I review and improve Swift Testing assertions and dependencies?

Review Swift Testing assertions and dependencies by identifying inappropriate expectations, verifying dependency-injected networking mocks, and ensuring proper test scoping and parameterized test structures.

Can I use Swift Testing for UI tests instead of XCTest?

Swift Testing is designed for unit and integration tests, so you should preserve UI tests in XCTest rather than migrating them, ensuring appropriate framework usage for each test type.

Why do my parameterized Swift Testing tests fail with hidden global state?

Parameterized Swift Testing tests fail when relying on hidden global state because they are designed for parallel execution, requiring dependency injection and actor isolation to ensure safe, concurrent test runs.
