how to setup Fake controller context and httpsession

Question

I am using NUnit and Fake it easy. I am planning to Setup which can be reusable across the project.

here is my setupCode:

IClient fake;
SampleController sController;
[SetUp]
public void Setup()
{
    sController = new SampleController();
    fake = A.Fake<IClient>();
    fakeContext =new  FakeContext(sController);

    sController = new SampleController(fake);
}

here is my FakeContextClass:

 public class FakeContext
 {
     HttpSessionStateBase fakeHttpSession;
     HttpContextBase fakeHttpContext;
     ControllerContext ControllerContext;

     public  FakeContext(Controller controller)
     {
         try
         {
             fakeHttpSession = A.Fake<HttpSessionStateBase>();
             fakeHttpContext = A.Fake<HttpContextBase>();

             fakeHttpSession.Contents["TestSession"] = new SaSession()
             {
                 DefaultUID = 1,
                 Name = "system",
                 LastName = "Test",
             };
             var fake = (SaSession)fakeHttpSession.Contents["TestSession"];
             A.CallTo(() => fakeHttpContext.Session).Returns(fakeHttpSession);
             A.CallTo(() => fakeHttpSession["TestSession"]).Returns(fake);
             ControllerContext = new ControllerContext(fakeHttpContext, new RouteData(), A.Fake<ControllerBase>());

             controller.ControllerContext = ControllerContext;
         }
    }
}

During Setup, when I pass controller which needs to be faked, I am able to get faked controller context of the passed controller. Also I want the HttpSessionStatebase also to be faked along with the context during TestSetup,so i don't need to fake the HttpSession for every call in the unit test methods.

 My test Method:   

[Test]
public async Task DetailsView()
{
    int UID = 0;
    string Name = "MedPlus";

    A.CallTo(() => fake.GetDataAsync<IEnumerable<Group>>(fakeHttpSession, "/ManagementSvc/v1/Groups?UID=" + UID ));

    ////Act
    var actionResult = await sController.DetailsView(UID,Name);
    var viewResult = actionResult as ViewResult;
    var grpModel = viewResult.Model as Model;

    //Assert
    Assert.IsNotNull(actionResult);
    Assert.AreEqual("GrpDetails", viewResult.ViewName);
    Assert.IsInstanceOf(typeof(Model), viewResult.Model);
}

If I fake HttpSessionStatebase in Test method,then I am able to get the fakeHttpSession.

Is there a way to fake HttpSessionState(fakeHttpSession) and hte controller context once so that the same instances are used in every test in my assembly?

I'm sorry. I'm not really sure what information you're after. Is your code not working as you'd like? Or are you just wondering about alternative implementations? — Blair Conrad, Aug 30 '16 at 13:18
I want to Setup both controller context and session in Setup so that i can reuse same context and session across all test methods in test class — AMDI, Aug 30 '16 at 13:30
Sounds like you want to use the NUnit attribute [SetUpFixture](https://github.com/nunit/docs/wiki/SetUpFixture-Attribute) to run your setup code, and isn't specific to FakeItEasy. I've marked the question as a duplicate of another question that asks how to run NUnit setup code once for an assembly. — Blair Conrad, Aug 30 '16 at 13:49

As an alternative, since you're looking for one-time initialization and access to a couple of objects, you could just implement a [Singleton](http://csharpindepth.com/Articles/General/Singleton.aspx) and not worry about NUnit's special attributes for one-time setup. — Blair Conrad, Aug 30 '16 at 13:58
Sorry for the confusion.I am looking for [Setup] attribute for each Test Class.I want to create and fake HttpSessionState in FakeContext class and reuse the fake session across the Test class — AMDI, Aug 31 '16 at 06:49
In that case, your question is s duplicate of http://stackoverflow.com/questions/23158500/is-there-a-way-to-have-a-setupfixture-that-runs-once-per-class-instead-of-once-p. You want a [OneTimeSetUp](https://github.com/nunit/docs/wiki/OneTimeSetUp-Attribute) inside your test class. (Called [TestFixtureSetUp](http://www.nunit.org/index.php?p=fixtureSetup&r=2.6.4) in NUnit 2.x.) — Blair Conrad, Aug 31 '16 at 10:26
