SKTestSession.buyProduct(identifier: options:) throws error

Hi,

Overview

• I am trying to write a unit test case to buy a storekit product.
• SKTestSession.buyProduct(identifier: options:) throws the error StoreKit.StoreKitError.notEntitled

Testcase Code

@Test func example() async throws {
    let session = try SKTestSession(configurationFileNamed: "VehicleStore")
    session.disableDialogs = true
    session.clearTransactions()
    do {
        let transaction = try await session.buyProduct(identifier: "nonconsumable.car", options: [])
        print(transaction)
    } catch {
        // Throws StoreKit.StoreKitError.notEntitled
        print("Error: \(error)")
    }
}

Storekit configuration file

Note

• In-App purchases capability is added
• StoreKit configuration file is used in testcase

Environment:

• macOS 26.5.2 (25F84)
• Xcode 26.6 (17F113)
