What is the primary difference between Swift Testing and XCTest in this skill?

This skill focuses on the new Swift Testing framework which uses macros like @Test instead of class-based inheritance and specific naming conventions required by XCTest.

How does the skill handle failed assertions?

It provides guidance on using #expect for non-halting checks and #require for assertions that must pass to continue the test, such as unwrapping an optional.

Does it support testing asynchronous code?

Absolutely. It provides specific implementation patterns for testing functions that use Swift's async/await concurrency model.

Can I use this skill to migrate existing projects?

Yes, the skill includes best practices for mixing Swift Testing and XCTest in the same project to allow for a gradual, incremental migration.

보안 및 테스팅

Guides the implementation of modern unit tests using Apple’s Swift Testing framework with macro-driven patterns.

This skill provides specialized guidance for developers using Apple's modern Swift Testing framework as an alternative to XCTest. It helps you write clear, concise tests using Swift macros like @Test, #expect, and #require, facilitating more readable test navigators and robust assertion logic. Whether you are building new iOS/macOS apps or incrementally migrating away from XCTest, this skill ensures your test suites leverage modern features like async/await support, optional unwrapping within tests, and custom issue recording.
