Snapshot testing in SwiftUI allows developers to create tests that verify the visual appearance of UI components. With the rise of SwiftUI, traditional snapshot testing methods have evolved, leveraging frameworks such as XCTest and SnapshotTesting. This guide provides a simple example of how to implement snapshot testing for SwiftUI views.

Learn how to use snapshot testing in SwiftUI applications to ensure that your UI components render as expected. This article covers the basics and provides a practical coding example.
// Example of a SwiftUI snapshot test
import SwiftUI
import XCTest
@testable import YourAppModule
class YourViewTests: XCTestCase {
func testExampleViewSnapshot() {
let view = ExampleView() // Initialize your SwiftUI view here
let vc = UIHostingController(rootView: view)
// Snapshot test using SnapshotTesting framework
assertSnapshot(matching: vc, as: .image)
}
}
