SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides a modern, streamlined approach to writing tests in Swift, replacing the older XCTest framework with more expressive syntax and powerful features.

Core Features & Use Cases

  • Modern Syntax: Uses @Test, #expect, and @Suite for clearer, more concise test definitions.
  • Parameterized Tests: Easily run the same test logic with multiple data sets.
  • Async Testing: Built-in support for testing asynchronous code using Swift's structured concurrency.
  • Observable Model Testing: Streamlined testing for @Observable models.
  • Migration Path: Provides clear guidance for migrating existing XCTest suites.
  • Use Case: When developing a new Swift feature, use this Skill to write comprehensive unit and integration tests that ensure code quality and prevent regressions.

Quick Start

Write a new test for the ShoppingList model using the @Test attribute and #expect macro.

Frequently Asked Questions about testing-swift

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

FAQPage Schema
How do I write unit tests in Swift using the @Test attribute and #expect macro?▼

Swift unit testing uses the @Test attribute for test functions and #expect for assertions, providing a modern, expressive syntax to define and validate code behavior clearly.

What is the best way to migrate existing XCTest suites to the modern Swift testing framework?▼

Migrating XCTest suites to modern Swift testing requires following provided migration guidance to transition XCTest classes into @Suite structures and assertions into #expect macros.

How do I run parameterized tests with multiple data sets in Swift?▼

Parameterized tests in Swift allow you to easily run the same test logic with multiple data sets by applying the modern testing framework's built-in data-driven test capabilities.

Does modern Swift testing support async code and structured concurrency?▼

Modern Swift testing fully supports async code, offering built-in capabilities to test asynchronous operations using Swift's structured concurrency directly within @Test functions.

Can I test @Observable models using the modern Swift testing framework?▼

Yes, you can test @Observable models using the Swift testing framework, which provides streamlined support for validating state changes and observable properties in your tests.
