Unit testing for adding record in DB
===

I am using unit testing first time.

I have created the class 'CAR' using entity framework.
I have following code in my project

    namespace EntityFrameworkExample
    {
        class Program
        {
            static void Main(string[] args)
            {
    
              public static void AddCar()
              {
    
                SampleDBEntities db = new SampleDBEntities();
                Car car = new Car();
                car.Brand = "Ford";
                car.Model = "Mastang";
                db.Cars.AddObject(car);
                db.SaveChanges();
                Console.WriteLine("Record Saved");
                Console.ReadLine();
             }
          }
      } 
    }

Now I want to perform unit testing on this method.

I have added unit test project as well added ref of above project to it...
but I am confused abt how to call it  ? 

I have writen below code 

    namespace UnitTest
    {
        /// <summary>
        /// Summary description for UnitTest1
        /// </summary>
        [TestClass]
        public class UnitTest1
        {
    
            [TestMethod]
            public void AddCar()
            {
    
                SampleDBEntities e = new SampleDBEntities();
         
    
                //what to do next ? ////////////////////////////////
    
          }
        
        }
    }

I am confused abt next step what should I write ?
