To make this test to work, I should change the signature of your class. Because you can not make a stub or a mock of your class Webservice, because you are creating it in the method.
class YourClass
{
private readeonly WebService _ws;
public YourClass(WebService ws)
{
_ws=ws;
}
[HttpPost]
public JsonResult GetUserListFromWebService()
{
JsonResult jsonResult = new JsonResult();
jsonResult.Data = _ws.GetUserList(User.Identity.Name);
return jsonResult;
}
}
Now you can in your test easily mock the class WebService with Moq or other frameworks. To make it eaven easier you shoul create an interface to your class WebService that implements the method GetUserList();
And to mock the User.Identy
public SomeController CreateControllerForUser(string userName)
{
var mock = new Mock<ControllerContext>();
mock.SetupGet(p => p.HttpContext.User.Identity.Name).Returns(userName);
mock.SetupGet(p => p.HttpContext.Request.IsAuthenticated).Returns(true);
var controller = new SomeController();
controller.ControllerContext = mock.Object;
return controller;
}
