我有一个web服务，我试图单元测试。在服务中，它从HttpContext中提取了几个值，如下所示:
m_password = (string)HttpContext.Current.Session["CustomerId"];
m_userID = (string)HttpContext.Current.Session["CustomerUrl"];
在单元测试中，我使用一个简单的工作请求创建上下文，如下所示:
SimpleWorkerRequest request = new SimpleWorkerRequest("", "", "", null, new StringWriter());
HttpContext context = new HttpContext(request);
HttpContext.Current = context;
然而，每当我试图设置HttpContext.Current.Session的值时
HttpContext.Current.Session["CustomerId"] = "customer1";
HttpContext.Current.Session["CustomerUrl"] = "customer1Url";
我得到空引用异常，说HttpContext.Current.Session是空的。
是否有方法在单元测试中初始化当前会话?
我之前写过一些关于这方面的东西。

希望能有所帮助。
[TestInitialize]
public void TestSetup()
{
// We need to setup the Current HTTP Context as follows:
// Step 1: Setup the HTTP Request
var httpRequest = new HttpRequest("", "http://localhost/", "");
// Step 2: Setup the HTTP Response
var httpResponce = new HttpResponse(new StringWriter());
// Step 3: Setup the Http Context
var httpContext = new HttpContext(httpRequest, httpResponce);
var sessionContainer =
new HttpSessionStateContainer("id",

CallingConventions.Standard,
new[] { typeof(HttpSessionStateContainer) },

.Invoke(new object[] { sessionContainer });
// Step 4: Assign the Context
HttpContext.Current = httpContext;

}
在asp.net Core / MVC 6 rc2中，你可以设置HttpContext
var SomeController controller = new SomeController();
controller.ControllerContext = new ControllerContext();
controller.ControllerContext.HttpContext = new DefaultHttpContext();
controller.HttpContext.Session = new DummySession();
Rc 1为
var SomeController controller = new SomeController();
controller.ActionContext = new ActionContext();
controller.ActionContext.HttpContext = new DefaultHttpContext();
controller.HttpContext.Session = new DummySession();

考虑使用Moq
new Mock<ISession>();
如果您正在使用MVC框架，这应该可以工作。我使用Milox的FakeHttpContext并添加了一些额外的代码行。这个想法来自这个帖子:
http://codepaste.net/p269t8
这似乎在MVC 5中工作。我还没有尝试在早期版本的MVC。
HttpContext.Current = MockHttpContext.FakeHttpContext();
var wrapper = new HttpContextWrapper(HttpContext.Current);
MyController controller = new MyController();
controller.ControllerContext = new ControllerContext(wrapper, new RouteData(), controller);
string result = controller.MyMethod();

我正在寻找一种比上面提到的选项更少侵入性的东西。最后，我提出了一个俗气的解决方案，但它可能会让一些人行动得更快一些。
首先，我创建了一个TestSession类:
class TestSession : ISession
{
public TestSession()
{
Values = new Dictionary<string, byte[]>();
}
public string Id
{
get
{
return "session_id";
}
}
public bool IsAvailable
{
get
{
return true;
}
}
public IEnumerable<string> Keys
{
get { return Values.Keys; }
}
public Dictionary<string, byte[]> Values { get; set; }
public void Clear()
{
Values.Clear();
}
public Task CommitAsync()
{
throw new NotImplementedException();
}
public Task LoadAsync()
{
throw new NotImplementedException();
}
public void Remove(string key)
{
Values.Remove(key);
}
public void Set(string key, byte[] value)
{
if (Values.ContainsKey(key))
{
Remove(key);
}
Values.Add(key, value);
}
public bool TryGetValue(string key, out byte[] value)
{
if (Values.ContainsKey(key))
{
value = Values[key];
return true;
}
value = new byte[0];
return false;
}
}
然后我在控制器的构造函数中添加了一个可选参数。如果该参数存在，则将其用于会话操作。否则，使用HttpContext。会话:
class MyController
{
private readonly ISession _session;
public MyController(ISession session = null)
{
_session = session;
}
public IActionResult Action1()
{
Session().SetString("Key", "Value");
View();
}
public IActionResult Action2()
{
ViewBag.Key = Session().GetString("Key");
View();
}
private ISession Session()
{
return _session ?? HttpContext.Session;
}
}
现在我可以将我的TestSession注入到控制器中:
class MyControllerTest
{
private readonly MyController _controller;
public MyControllerTest()
{
var testSession = new TestSession();
var _controller = new MyController(testSession);
}
}
