To migrate an XCTest suite to Swift Testing, you can refactor existing test functions into Swift Testing suites, replacing XCTest assertions with `#expect` and `#require` macros. The skill provides strategies for incremental migration, ensuring tests remain functional during the transition.

Parameterized tests in Swift Testing allow you to run the same test logic with multiple inputs, while traits and tags help organize tests for better filtering in CI. The skill guides you on structuring tests, applying traits, and leveraging these features for improved test suite organization.

Debugging flaky tests and parallel execution issues in Swift Testing involves analyzing test structure and async waiting patterns. The skill offers solutions for identifying race conditions, optimizing parallel execution, and improving overall test stability and maintainability.

Yes, Swift Testing works with both Apple-platform and Swift server projects. The skill provides expert guidance on writing, reviewing, and debugging tests using the modern Swift Testing framework, ensuring robust and efficient test suites across different Swift environments.

Swift Testing offers modern features like parameterized tests, traits for CI filtering, and improved parallel execution compared to XCTest. The skill helps you modernize your test suite, leveraging new features for better organization, maintainability, and test quality.

Handling async patterns in Swift Testing requires proper structuring of tests and using async waiting mechanisms. The skill provides guidance on writing async tests, ensuring they are parallel-safe, and avoiding common pitfalls associated with asynchronous test execution.
