Migrating XCTest to Swift Testing involves mapping XCTest constructs to modern equivalents, structuring tests as suites, and reviewing async behavior to prevent regressions. It guides XCTest-to-Swift Testing conversion while enforcing correct conventions.

Async Swift Testing tests often fail due to incorrect actor isolation, confirmation usage, or time limits. Reviewing async behavior, actor isolation, and mocking ensures tests remain reliable and prevents hidden concurrency issues.

Writing reliable Swift Testing unit tests requires using struct suites, correct assertions, and traits. Modern Swift Testing-first authoring produces robust tests for business logic by enforcing conventions and avoiding common pitfalls.

Reviewing Swift Testing test files involves checking for genuine problems only, organized by file with targeted before/after fixes. It avoids nitpicks and reports real issues in async/await concurrency, mocks, and structure.

Swift Testing supports integration tests with networking mocks and time limits. It checks async behavior, confirmation usage, and mocking to prevent flaky tests, ensuring reliable integration test execution.

Swift Testing works with Swift 6.2+ concurrency features, including confirmations and actor isolation. It enforces modern Swift Testing conventions and reference-based rules for correctness-focused test review and authoring.
