NUll exception in filling a querystring by mocing framework
- by user564101
There is a simple controller that a querystring is read in constructor of it.
public class ProductController : Controller
{
parivate string productName;
public ProductController()
{
productName = Request.QueryString["productname"];
}
public ActionResult Index()
{
ViewData["Message"] = productName;
return View();
}
}
Also I have a function in unit test that create an instance of this Controller and I fill the querystring by a Mock object like below.
[TestClass]
public class ProductControllerTest
{
[TestMethod]
public void test()
{
// Arrange
var querystring = new System.Collections.Specialized.NameValueCollection { { "productname", "sampleproduct"} };
var mock = new Mock<ControllerContext>();
mock.SetupGet(p => p.HttpContext.Request.QueryString).Returns(querystring);
var controller = new ProductController();
controller.ControllerContext = mock.Object;
// Act
var result = controller.Index() as ViewResult;
// Assert
Assert.AreEqual("Index", result.ViewName);
}
}
Unfortunately Request.QueryString["productname"] is null in constructor of ProductController when I run test unit.
Is ther any way to fill a querystrin by a mocking and get it in constructor of a control?
