What are mocking and stubbing techniques for MapKit in Swift?

Mocking and stubbing techniques in MapKit for Swift allow developers to create unit tests without relying on the actual MapKit API. This provides a controlled environment for testing map-related functionality while avoiding external dependencies.

// Example of Stubbing a MapKit Call in Swift import XCTest import MapKit class MapViewModel { var locationManager: CLLocationManager? func requestLocation() { locationManager = CLLocationManager() locationManager?.requestWhenInUseAuthorization() } } class MockLocationManager: CLLocationManager { override func requestWhenInUseAuthorization() { // Mock behavior if needed } } class MapViewModelTests: XCTestCase { var viewModel: MapViewModel! override func setUp() { super.setUp() viewModel = MapViewModel() viewModel.locationManager = MockLocationManager() // Stubbing the location manager } func testRequestLocation() { viewModel.requestLocation() // Assert and validate the behavior } }
