What is the recommended pattern for mocking data?

The skill promotes the Mock Repository pattern using protocols and @unchecked Sendable to decouple your business logic from external API or database calls during testing.

Can it help with visual regression?

Absolutely. It provides code snippets for implementing snapshot testing to catch unintended UI changes across different device themes and font sizes.

How does it handle UI testing for SwiftUI?

It utilizes XCUIApplication and accessibility identifiers to create reliable UI tests that simulate real user interactions and verify screen content.

Does this skill support testing Swift's async/await code?

Yes, it includes specific patterns for testing asynchronous operations, verifying data loads, and ensuring proper Task cancellation behavior.

安全与测试

Implements comprehensive testing strategies for SwiftUI applications, including unit, UI, snapshot, and asynchronous tests.

The SwiftUI Testing skill equips Claude with specialized knowledge for architecting and writing robust test suites for iOS applications. It provides standardized implementation patterns for XCTest, ranging from unit testing ViewModels using the Mock Repository pattern to complex UI automation through accessibility identifiers. It also covers visual regression via snapshot testing and best practices for validating modern Swift concurrency features like async/await and Task cancellation, ensuring your application remains stable and visually consistent across updates.
