How to mock the Request for ASP.Net WebForm Page?

Question

I have following asp.net Page Contact and having TestHandlerDemoClass which is having one method I want to write a unit test case for that method but when I tried it using MSTest project it throws exception like Request not available in this context

public partial class Contact : Page
    {

    }
 public class TestHandlerDemoClass
    {
 public void MyTestMethod(Page mypage)
        {
       string id= mypage.Request["EntityId"]

//here I'm not getting Request inside mypage

My Test Project code -

[TestClass]
    public class UnitTest1
    {
        [TestMethod]
        public void NullCheck()
        {
            try
            {
                Contact contactPage = new Contact();
                TestHandlerDemoClass mydemo = new TestHandlerDemoClass();
                mydemo.MyTestMethod(contactPage);
            }
            catch (Exception ex)
            {
                Assert.AreEqual(ex.Message, "Id not found");
            }
        }
    }

here in above ex I got message like {"Request is not available in this context"}

I 'm just trying to write unit test cases for method `

public void MyTestMethod(Page mypage)

which takes Page mypage as parameter.

how to do it?

By mocking your Contact class the test will pass, the problem is most of the unit testing tools doesn't allow to mock a Non-virtual Class. im using Typemock where its possible to mock almost any type of Object without changing your code, and its realy esay to use.

for example:

  [TestMethod]
        public void NullCheck()
        {
            try
            {
                var contactPage = Isolate.Fake.Instance<Contact>();
                TestHandlerDemoClass t = new TestHandlerDemoClass();
                t.MyTestMethod(contactPage);
            }
            catch (Exception ex)
            {
                Assert.AreEqual(ex.Message, "Id not found");
            }
        }

how and where it will assign a request value `EntityId`? – Neo Nov 06 '16 at 09:20 — Neo, Nov 06 '16 at 09:20

I'm not an expert in unit testing, but I think you should pass a mock object like is answered here: How to mock the Request on Controller in ASP.Net MVC?

I got your point thanks but instead of mock it would be more simpler if I got to know how to pass a page request from unit test method – Neo Nov 05 '16 at 11:12
An [HttpRequest object](https://msdn.microsoft.com/it-it/library/system.web.httprequest(v=vs.110).aspx) is something quite complicated, that is build starting from what is sent by a client able to send http request (often, a browser). I doubt you can find something simpler than a mock – Gian Paolo Nov 05 '16 at 11:58
