Mocking httpcontext in dotnet core

Make sure the reference to httpcontext is moved into some service. That service is injected into the controller. And can therefore be mocked.

add

services.AddSingleton\<IHttpContextAccessor, HttpContextAccessor>();

to the startup.cs ConfigureServices method. then

public class UserService : IUserService
{
private readonly IHttpContextAccessor _httpContextAccessor;

public UserService(IHttpContextAccessor httpContextAccessor)
{
_httpContextAccessor = httpContextAccessor;
}

public bool IsUserLoggedIn()
{
var context = _httpContextAccessor.HttpContext;
return context.User.Identities.Any(x => x.IsAuthenticated);
}
}
