How do I set up unit tests and mocks with StoreKit 2 in Swift?

Unit tests in Swift are essential for ensuring the robustness of your application. With the introduction of StoreKit 2, testing in-app purchases and subscriptions has become more manageable. This guide will show you how to set up unit tests and create mocks for StoreKit 2 in Swift.

import XCTest import StoreKit // Mock class for StoreKit class MockProduct: Product { let productId: String let price: Decimal let currency: String init(productId: String, price: Decimal, currency: String) { self.productId = productId self.price = price self.currency = currency } } // Your test class class StoreKitTests: XCTestCase { func testFetchProducts() { let mockProduct = MockProduct(productId: "com.example.app.subscription", price: 9.99, currency: "USD") // Assuming we have a method to fetch products let products = fetchProducts() // Replace this with your actual implementation XCTAssertEqual(products.count, 1) XCTAssertEqual(products[0].productId, mockProduct.productId) XCTAssertEqual(products[0].price, mockProduct.price) } }
