How to moq HttpContext on Asp net Core

I have an asp .net core project, and practically in each action we use session, my question is how to test it if I don't have sessionRepository. Controller tests crush because session in controller is null. I try to Moq IHttpContextAcessor and it also doesn't work.

I try this:

HttpContext.Current = new HttpContext(new HttpRequest(null, "http://tempuri.org", null), new HttpResponse(null));

but HttpContext doesn't contain the definition for Current. (using Microsoft.AspNetCore.Http;)

Is there any way to moq or test controllers that use HttpContext and sessions?

You can use ControllerContext to set the context to be DefaultHttpContext which you can modify to your needs.

var ctx = new ControllerContext() { HttpContext = new DefaultHttpContext()};
var tested = new MyCtrl();
tested.ControllerContext = ctx;

The controller has an Controller context which you can set (i used the default one) :

Controller.ControllerContext = new ControllerContext                                                
{
    HttpContext = new DefaultHttpContext()
};

After time I think is bad idea to moq Session, better way is to create a IOC container, for example we create ISessionManager interface with methods which return stored in session objects:

public class SessionManager:ISessionManager{

public User GetUser(){
  User usr= JsonConvert.DeserializeObject<User>(HttpContext.Session.GetString("USER"));
  return usr;
}

***here we get data from session***

}

for UnitTest we just create a new class which implement ISessionManager and use it for test Controller's.

public class SessionManagerTest:ISessionManager{

public User GetUser(){
  User usr=new User();
  ...initialize all fields
  return usr;
}
