SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill resolves the complexity of adopting the modern Swift Testing framework, helping developers migrate from XCTest, debug flaky tests, and write robust, parallel-safe test suites.

Core Features & Use Cases

  • Modern Assertion Syntax: Provides guidance on using #expect and #require for expressive, readable test diagnostics.
  • Migration & Parallelization: Offers strategies for incremental XCTest migration and resolving shared-state issues to enable parallel execution.
  • Use Case: Use this skill when you need to convert a legacy XCTest suite to Swift Testing, or when you are struggling to identify why your integration tests are failing intermittently in CI.

Quick Start

Use the swift-testing-expert skill to analyze my current XCTest suite and suggest an incremental migration plan to Swift Testing.

Frequently Asked Questions about swift-testing-expert

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

FAQPage Schema
How do I migrate my XCTest suite to Swift Testing incrementally?▼

To migrate XCTest to Swift Testing incrementally, you run both frameworks side by side. This skill provides strategies for resolving shared-state issues to enable parallel execution while converting tests step by step.

Why are my Swift Testing integration tests failing intermittently in CI?▼

Intermittent CI failures often stem from shared state breaking parallel test execution. This skill helps debug flaky tests by enforcing parallel-safe test architecture and best practices for async testing.

What is the best way to use parameterized tests and tags in Swift Testing?▼

The best way to use parameterized tests and tags is by adopting modern testing patterns. This skill provides expert guidance on implementing these features to ensure high-quality test diagnostics and maintainability.

Does Swift Testing work with server-side Swift projects?▼

Yes, Swift Testing works with server-side Swift projects. This skill provides expert guidance on implementing the framework for both Apple-platform and server-side environments, including async testing best practices.

How do #expect and #require improve test diagnostics compared to XCTest?▼

#expect and #require improve test diagnostics by providing expressive and readable syntax. This skill guides you in using these modern assertions to ensure high-quality diagnostics and maintainability over traditional XCTest assertions.
