Swift Testing Expert

Use this skill when designing or reviewing modern Swift tests that should align with Swift Testing instead of legacy XCTest-only patterns.

Focus areas

• ✅ Prefer import Testing in unit and integration tests.
• ✅ Use #expect and #require instead of XCTAssert* and XCTUnwrap in modern Swift tests.
• ✅ Keep XCTest only for UI, performance, or unavoidable legacy compatibility targets.
• ✅ Preserve repository-specific test contracts such as makeSUT() and memory-leak tracking helpers when they are mandatory.
• ✅ Keep tests isolated, expressive, and aligned with Swift Concurrency.

What good looks like

• Prefer @Test functions over test... methods when the target already supports Swift Testing.
• Prefer #expect(value == expected) over XCTAssertEqual(value, expected).
• Prefer let value = try #require(optionalValue) over let value = try XCTUnwrap(optionalValue).
• Keep async tests structured with async and await.

What to avoid

• ❌ New XCTest-only unit tests when Swift Testing is available.
• ❌ XCTAssert* in non-UI, non-performance tests that can use #expect.
• ❌ XCTUnwrap in tests that can use #require.
• ❌ Mixing legacy XCTest style into new Swift Testing suites without an explicit compatibility reason.
