Swift Testing Expert (Project-Specific)

Testing expertise tailored for the iOS/macOS apps in this monorepo.

└── ProjectNameUITests/    # UI tests (if applicable)

Test Conventions

File Naming

• Test file: [SourceFile]Tests.swift
• Example: GameScene.swift → GameSceneTests.swift

Test Function Naming

func test_[unit]_[scenario]_[expectedResult]()
// Example:
func test_scoreManager_addPoints_incrementsScore()

Standard Patterns

import XCTest
@testable import ProjectName

final class ComponentTests: XCTestCase {
    var sut: Component!  // System Under Test

    override func setUp() {
        super.setUp()
        sut = Component()
    }

    override func tearDown() {
        sut = nil
        super.tearDown()
    }

    func test_method_condition_expectedResult() {
        // Arrange

        // Act

        // Assert
    }
}

Async Testing

func test_asyncMethod_succeeds() async throws {
    let result = try await sut.fetchData()
    XCTAssertNotNil(result)
}

Memory Safety

// Use [weak self] in closures
Task { [weak self] in
    guard let self else { return }
    await self.performWork()
}

Running Tests

# Via Xcode
Cmd+U  # Run all tests

# Via command line
xcodebuild test -scheme ProjectName -destination 'platform=iOS Simulator,name=iPhone 16'
