现在我正在使用Core Data,如何对我的模型进行单元测试？

import XCTest
import CoreData

class MyModelTests: XCTestCase {
    var managedObjectModel: NSManagedObjectModel!
    var persistentStoreCoordinator: NSPersistentStoreCoordinator!
    var managedObjectContext: NSManagedObjectContext!

    override func setUp() {
        super.setUp()

        // Load the managed object model from the Core Data model file
        let modelURL = Bundle(for: type(of: self)).url(forResource: "MyModel", withExtension: "momd")!
        managedObjectModel = NSManagedObjectModel(contentsOf: modelURL)!

        // Create the persistent store coordinator
        persistentStoreCoordinator = NSPersistentStoreCoordinator(managedObjectModel: managedObjectModel)

        // Create the managed object context
        managedObjectContext = NSManagedObjectContext(concurrencyType: .mainQueueConcurrencyType)
        managedObjectContext.persistentStoreCoordinator = persistentStoreCoordinator

        // Add an in-memory persistent store
        let store = persistentStoreCoordinator.addPersistentStore(ofType: NSInMemoryStoreType, configurationName: nil, at: nil, options: nil)
        XCTAssertNotNil(store)
    }

    func testCreateMyEntity() {
        // Create a new MyEntity object
        let myEntity = NSEntityDescription.insertNewObject(forEntityName: "MyEntity", into: managedObjectContext) as! MyEntity

        // Set the properties of the MyEntity object
        myEntity.name = "Test"
        myEntity.age = 42

        // Save the managed object context
        XCTAssertNoThrow(try managedObjectContext.save())

        // Verify that the properties were set correctly
        XCTAssertEqual(myEntity.name, "Test")
        XCTAssertEqual(myEntity.age, 42)
    }
}
