To migrate XCTest suites to the Swift Testing framework, you transition traditional test classes to modern `@Test` functions. You replace `XCTest` assertions with `#expect` and `#require` macros while adopting best practices for testable architecture.

Yes, Swift Testing supports parameterized tests, test traits, and tags for sophisticated test organization. You can run the same test logic across multiple scenarios by passing arguments directly into the `@Test` macro function signature.

The Swift Testing framework fully supports Xcode 16+ and Swift 6+ environments. It is designed to integrate seamlessly with modern Xcode tooling while handling advanced features like async code and mocking.

The best way to handle async code and mocking in Swift unit tests is using the Swift Testing framework. It provides built-in support for asynchronous test functions, allowing you to fetch user data and validate complex async operations robustly.

You handle known issues and test traits in modern Swift unit tests using the Swift Testing framework's built-in organization features. Traits and tags allow you to categorize tests, while known issue markers prevent expected failures from breaking your suite.
