Asp.net MVC测试

Question

CustomerController.cs： -

public ActionResult Details(int id) 
    { 
     CustomerDataContext cs = new CustomerDataContext(); 
     var query = cs.Customers.Where(m => m.CustId == id).Select(m => m); 
     Customer cust = new Customer(); 
     foreach (var q in query) 
     { 

      cust.CustId = q.CustId; 
      cust.Name = q.Name; 
      cust.Salary = q.Salary; 
      cust.JoiningDate = q.JoiningDate; 
     } 
     return View("Details",cust); 
    } 

CustomerControllerTest.cs： -

[TestMethod] 
public void TestDetailsViewData() 
{ 
    CustomerController controller = new CustomerController(); 
    var result = controller.Details(5) as ViewResult; 
    Customer cust = result.ViewData.Model as Customer; 
    Assert.AreEqual(5,cust.CustId); 

} 

我的测试失败，我收到以下错误消息话题： 试验方法MvcApplication1.Tests。 Controllers.CustomerControllerTest.TestDetailsViewData引发异常： System.NullReferenceException：未将对象引用设置为对象的实例。

问题已解决。 它只是没有连接字符串。
