Practical SwiftUI Snapshot Testing

  1. Compare Actual SwiftUI View with expected image with color accuracy
  2. Overwrite Expected with Actual on failure
  3. Attach Image Difference to test failure

This allows simple snapshot tests for SwiftUI views and previews.

Installation

Add Swift Package to a project Test target

Example

See Example iOS app project with SnapshotTests.swift

func testViews() {
    verifySnapshot(FavoriteView_Previews.self)
    verifySnapshot(ContentView())
    verifySnapshot(Text("SwiftUI").foregroundColor(.red), "example")
}
