We had to mock <code>HttpContext</code> by using a <code>HttpContextManager</code> and calling the factory from within our application as well as the Unit Tests

<pre><code>public class HttpContextManager 
{
 private static HttpContextBase m_context;
 public static HttpContextBase Current
 {
 get
 {
 if (m_context != null)
 return m_context;

 if (HttpContext.Current == null)
 throw new InvalidOperationException("HttpContext not available");

 return new HttpContextWrapper(HttpContext.Current);
 }
 }

 public static void SetCurrentContext(HttpContextBase context)
 {
 m_context = context;
 }
}
</code></pre>

You would then replace any calls to <code>HttpContext.Current</code> with <code>HttpContextManager.Current</code> and have access to the same methods. Then when you're testing, you can also access the <code>HttpContextManager</code> and mock your expectations

This is an example using <a href="https://www.nuget.org/packages/Moq/" rel="noreferrer">Moq</a>:

<pre><code>private HttpContextBase GetMockedHttpContext()
{
 var context = new Mock&lt;HttpContextBase&gt;();
 var request = new Mock&lt;HttpRequestBase&gt;();
 var response = new Mock&lt;HttpResponseBase&gt;();
 var session = new Mock&lt;HttpSessionStateBase&gt;();
 var server = new Mock&lt;HttpServerUtilityBase&gt;();
 var user = new Mock&lt;IPrincipal&gt;();
 var identity = new Mock&lt;IIdentity&gt;();
 var urlHelper = new Mock&lt;UrlHelper&gt;();

 var routes = new RouteCollection();
 MvcApplication.RegisterRoutes(routes);
 var requestContext = new Mock&lt;RequestContext&gt;();
 requestContext.Setup(x =&gt; x.HttpContext).Returns(context.Object);
 context.Setup(ctx =&gt; ctx.Request).Returns(request.Object);
 context.Setup(ctx =&gt; ctx.Response).Returns(response.Object);
 context.Setup(ctx =&gt; ctx.Session).Returns(session.Object);
 context.Setup(ctx =&gt; ctx.Server).Returns(server.Object);
 context.Setup(ctx =&gt; ctx.User).Returns(user.Object);
 user.Setup(ctx =&gt; ctx.Identity).Returns(identity.Object);
 identity.Setup(id =&gt; id.IsAuthenticated).Returns(true);
 identity.Setup(id =&gt; id.Name).Returns("test");
 request.Setup(req =&gt; req.Url).Returns(new Uri("http://www.google.com"));
 request.Setup(req =&gt; req.RequestContext).Returns(requestContext.Object);
 requestContext.Setup(x =&gt; x.RouteData).Returns(new RouteData());
 request.SetupGet(req =&gt; req.Headers).Returns(new NameValueCollection());

 return context.Object;
}
</code></pre>

and then to use it within your unit tests, I call this within my Test Init method

<pre><code>HttpContextManager.SetCurrentContext(GetMockedHttpContext());
</code></pre>

you can then, in the above method add the expected results from Session that you're expecting to be available to your web service.

blocks|key|413980|text|您可以通过创建一个新HttpContext来“伪造它”，如下所示：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|413981|http://www.necronet.org/archive/2010/07/28/unit-testing-code-that-uses-httpcontext-current-session.aspx|413982|我将该代码放在一个静态助手类中，如下所示：|413983|public+static+HttpContext+FakeHttpContext()

}|code-block|syntax|javascript|413984|或者，不使用反射来构造新的HttpSessionState实例，您可以直接将HttpSessionStateContainer附加到HttpContext+(根据Brent+M.Spell的评论)：|413985|SessionStateUtility.AddHttpSessionStateToContext(httpContext,+sessionContainer);|413986|然后你可以在你的单元测试中调用它，就像这样：|413987|HttpContext.Current+=+MockHelper.FakeHttpContext();|413988|entityMap|0|LINK|mutability|MUTABLE|url^0|A|B|0|0|2V|0|0|0|0|D|G|12|P|1U|B|0|0|0|0^^$0|@$1|2|3|4|5|6|7|13|8|@$9|14|A|15|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|16|8|@]|D|@$9|17|A|18|1|19]]|E|$]]|$1|H|3|I|5|6|7|1A|8|@]|D|@]|E|$]]|$1|J|3|K|5|L|7|1B|8|@]|D|@]|E|$M|N]]|$1|O|3|P|5|6|7|1C|8|@$9|1D|A|1E|B|C]|$9|1F|A|1G|B|C]|$9|1H|A|1I|B|C]]|D|@]|E|$]]|$1|Q|3|R|5|L|7|1J|8|@]|D|@]|E|$M|N]]|$1|S|3|T|5|6|7|1K|8|@]|D|@]|E|$]]|$1|U|3|V|5|L|7|1L|8|@]|D|@]|E|$M|N]]|$1|W|3|-4|5|6|7|1M|8|@]|D|@]|E|$]]]|X|$Y|$5|Z|10|11|E|$12|G]]]]

You can "fake it" by creating a new <code>HttpContext</code> like this:

<a href="http://www.necronet.org/archive/2010/07/28/unit-testing-code-that-uses-httpcontext-current-session.aspx" rel="noreferrer">http://www.necronet.org/archive/2010/07/28/unit-testing-code-that-uses-httpcontext-current-session.aspx</a>

I've taken that code and put it on an static helper class like so: 

<pre><code>public static HttpContext FakeHttpContext()
{
 var httpRequest = new HttpRequest("", "http://example.com/", "");
 var stringWriter = new StringWriter();
 var httpResponse = new HttpResponse(stringWriter);
 var httpContext = new HttpContext(httpRequest, httpResponse);

 var sessionContainer = new HttpSessionStateContainer("id", new SessionStateItemCollection(),
 new HttpStaticObjectsCollection(), 10, true,
 HttpCookieMode.AutoDetect,
 SessionStateMode.InProc, false);

 httpContext.Items["AspSession"] = typeof(HttpSessionState).GetConstructor(
 BindingFlags.NonPublic | BindingFlags.Instance,
 null, CallingConventions.Standard,
 new[] { typeof(HttpSessionStateContainer) },
 null)
 .Invoke(new object[] { sessionContainer });

 return httpContext;
}
</code></pre>

Or instead of using reflection to construct the new <code>HttpSessionState</code> instance, you can just attach your <code>HttpSessionStateContainer</code> to the <code>HttpContext</code> (as per Brent M. Spell's comment):

<pre><code>SessionStateUtility.AddHttpSessionStateToContext(httpContext, sessionContainer);
</code></pre>

and then you can call it in your unit tests like:

<pre><code>HttpContext.Current = MockHelper.FakeHttpContext();
</code></pre>

The answer that worked with me is what @Anthony had written, but you have to add another line which is 

<pre><code> request.SetupGet(req =&gt; req.Headers).Returns(new NameValueCollection());

so you can use this:

Try this: 

<pre><code> // MockHttpSession Setup
 var session = new MockHttpSession();

 // MockHttpRequest Setup - mock AJAX request
 var httpRequest = new Mock&lt;HttpRequestBase&gt;();

 // Setup this part of the HTTP request for AJAX calls
 httpRequest.Setup(req =&gt; req["X-Requested-With"]).Returns("XMLHttpRequest");

 // MockHttpContextBase Setup - mock request, cache, and session
 var httpContext = new Mock&lt;HttpContextBase&gt;();
 httpContext.Setup(ctx =&gt; ctx.Request).Returns(httpRequest.Object);
 httpContext.Setup(ctx =&gt; ctx.Cache).Returns(HttpRuntime.Cache);
 httpContext.Setup(ctx =&gt; ctx.Session).Returns(session);

 // MockHttpContext for cache
 var contextRequest = new HttpRequest("", "http://localhost/", "");
 var contextResponse = new HttpResponse(new StringWriter());
 HttpContext.Current = new HttpContext(contextRequest, contextResponse);

 // MockControllerContext Setup
 var context = new Mock&lt;ControllerContext&gt;();
 context.Setup(ctx =&gt; ctx.HttpContext).Returns(httpContext.Object);

 //TODO: Create new controller here
 // Set controller's ControllerContext to context.Object
</code></pre>

And Add the class:

<pre><code>public class MockHttpSession : HttpSessionStateBase
{
 Dictionary&lt;string, object&gt; _sessionDictionary = new Dictionary&lt;string, object&gt;();
 public override object this[string name]
 {
 get
 {
 return _sessionDictionary.ContainsKey(name) ? _sessionDictionary[name] : null;
 }
 set
 {
 _sessionDictionary[name] = value;
 }
 }

 public override void Abandon()
 {
 var keys = new List&lt;string&gt;();

 foreach (var kvp in _sessionDictionary)
 {
 keys.Add(kvp.Key);
 }

 foreach (var key in keys)
 {
 _sessionDictionary.Remove(key);
 }
 }

 public override void Clear()
 {
 var keys = new List&lt;string&gt;();

 foreach (var kvp in _sessionDictionary)
 {
 keys.Add(kvp.Key);
 }

 foreach(var key in keys)
 {
 _sessionDictionary.Remove(key);
 }
 }
}
</code></pre>

This will allow you to test with both session and cache.

In asp.net Core / MVC 6 rc2 you can set the <code>HttpContext</code>

<pre><code>var SomeController controller = new SomeController();

controller.ControllerContext = new ControllerContext();
controller.ControllerContext.HttpContext = new DefaultHttpContext();
controller.HttpContext.Session = new DummySession();
</code></pre>

rc 1 was

<pre><code>var SomeController controller = new SomeController();

controller.ActionContext = new ActionContext();
controller.ActionContext.HttpContext = new DefaultHttpContext();
controller.HttpContext.Session = new DummySession();
</code></pre>

Never mock.. never! The solution is pretty simple. Why fake such a beautiful creation like <code>HttpContext</code>? 

Push the session down! (Just this line is enough for most of us to understand but explained in detail below)

<code>(string)HttpContext.Current.Session["CustomerId"];</code> is how we access it now. Change this to 

<pre><code>_customObject.SessionProperty("CustomerId")
</code></pre>

When called from test, _customObject uses alternative store (DB or cloud key value[ <a href="http://www.kvstore.io/]" rel="nofollow noreferrer">http://www.kvstore.io/]</a> )

But when called from the real application, <code>_customObject</code> uses <code>Session</code>.

how is this done? well... Dependency Injection! 

So test can set the session(underground) and then call the application method as if it knows nothing about the session. Then test secretly checks if the application code correctly updated the session. Or if the application behaves based on the session value set by the test.

Actually, we did end up mocking even though I said: "never mock". Becuase we couldn't help but slip to the next rule, "mock where it hurts the least!". Mocking huge <code>HttpContext</code> or mocking a tiny session, which hurts the least? don't ask me where these rules came from. Let us just say common sense. Here is an interesting read on not mocking <a href="https://www.linkedin.com/pulse/before-you-feed-unit-test-beast-s-a-n-j-ay-mohan/" rel="nofollow noreferrer">as unit test can kills us</a>

Try this way..

<pre><code>public static HttpContext getCurrentSession()
 {
 HttpContext.Current = new HttpContext(new HttpRequest("", ConfigurationManager.AppSettings["UnitTestSessionURL"], ""), new HttpResponse(new System.IO.StringWriter()));
 System.Web.SessionState.SessionStateUtility.AddHttpSessionStateToContext(
 HttpContext.Current, new HttpSessionStateContainer("", new SessionStateItemCollection(), new HttpStaticObjectsCollection(), 20000, true,
 HttpCookieMode.UseCookies, SessionStateMode.InProc, false));
 return HttpContext.Current;
 }
</code></pre>

I have a web service I am trying to unit test. In the service it pulls several values from the <code>HttpContext</code> like so:

<pre><code> m_password = (string)HttpContext.Current.Session["CustomerId"];
 m_userID = (string)HttpContext.Current.Session["CustomerUrl"];
</code></pre>

in the unit test I am creating the context using a simple worker request, like so:

<pre><code>SimpleWorkerRequest request = new SimpleWorkerRequest("", "", "", null, new StringWriter());
HttpContext context = new HttpContext(request);
HttpContext.Current = context;
</code></pre>

However, whenever I try to set the values of <code>HttpContext.Current.Session</code>

<pre><code>HttpContext.Current.Session["CustomerId"] = "customer1";
HttpContext.Current.Session["CustomerUrl"] = "customer1Url";
</code></pre>

I get null reference exception that says <code>HttpContext.Current.Session</code> is null. 

Is there any way to initialize the current session within the unit test?
