SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Projects that use Swift Testing often suffer from outdated XCTest patterns, brittle async tests, hidden dependencies, and incorrect use of modern testing primitives; this Skill identifies those issues and prescribes precise, idiomatic fixes so tests are correct, reliable, and maintainable.

Core Features & Use Cases

  • Focused code reviews: Analyze test suites for correct use of Swift Testing conventions such as structs over classes, #expect/#require, parameterized tests, and avoidance of setUp/tearDown anti-patterns.
  • Async and concurrency validation: Verify confirmation(), actor isolation, serialized tests, time limits, and proper handling of legacy callback-style code via continuations.
  • XCTest migration and modernization: Provide before/after conversions from XCTest idioms, recommend parameterized tests, traits, attachments, and scoped TestTrait setups for task-local values.
  • Use Case: Migrate an iOS test target from XCTest to Swift Testing, fix flaky async tests, and produce a prioritized file-by-file list of changes with code snippets.

Quick Start

Ask the assistant to review the test target for Swift Testing compliance and return a file-by-file findings list with before/after fixes and a prioritized summary.

Frequently Asked Questions about swift-testing-pro

High-intent search queries and answers about installing and using this skill.

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

Swift Testing handles async tests by validating actor isolation, serialized execution, and time limits. It checks proper use of confirmation() expectations and continuations for legacy callback-style code, identifying flaky behavior and prescribing idiomatic fixes for reliable async test execution.

How do I write parameterized tests in Swift Testing?▼

Parameterized tests in Swift Testing replace repetitive XCTest loops by passing argument collections directly into test functions. Reviewing your test suite ensures parameterized tests are structured correctly with traits and attachments, improving coverage while reducing brittle test duplication.

What is the best way to review a Swift Testing suite for correctness?▼

Reviewing a Swift Testing suite for correctness requires checking for struct usage over classes, proper #expect/#require assertions, and avoidance of setUp/tearDown anti-patterns. A thorough code review analyzes test structure, actor isolation, and scoped TestTrait setups to produce concrete fixes.

Does Swift Testing support actor isolation and serialized tests?▼

Swift Testing supports actor isolation and serialized tests by validating concurrency boundaries and time limits within test functions. Analyze test suites to verify proper isolation, identify hidden dependencies, and ensure async behavior conforms to Swift 6.2+ concurrency standards.

Why are my async Swift Testing tests flaky?▼

Flaky async Swift Testing tests often stem from incorrect confirmation() usage, missing actor isolation, or improper legacy callback continuations. Analyze the test suite to validate async behavior, identify hidden dependencies, and apply concrete before/after code fixes for reliable execution.
