What are integration testing setup for Core ML in Swift?

Integration testing for Core ML in Swift involves setting up a test environment where you can validate the interaction between the Core ML model and your app’s components. This often includes loading a model, making predictions, and verifying the output against expected results.

Steps to Set Up Integration Testing for Core ML

  1. Import the Core ML Model: Ensure the model is included in your project.
  2. Create Test Cases: Use XCTest framework to write test cases for the model's functionality.
  3. Load the Model: In your test, load the Core ML model.
  4. Make Predictions: Pass sample data to the model and retrieve predictions.
  5. Assert Results: Verify that the predictions match the expected outputs.

Example of Core ML Integration Testing

import XCTest import CoreML class CoreMLModelTests: XCTestCase { var model: YourModelName! override func setUp() { super.setUp() // Load your Core ML model model = try? YourModelName(configuration: MLModelConfiguration()) } func testModelPrediction() { // Prepare sample input data let input = YourModelNameInput(sampleData: ...) // Make prediction let prediction = try? model.prediction(input: input) // Verify the output XCTAssertNotNil(prediction) XCTAssertEqual(prediction?.outputValue, expectedOutput) } }
