How to write a test for accounts controller for forms authenticate
- by Anil Ali
Trying to figure out how to adequately test my accounts controller. I am having problem testing the successful logon scenario.
Issue 1) Am I missing any other tests.(I am testing the model validation attributes separately)
Issue 2) Put_ReturnsOverviewRedirectToRouteResultIfLogonSuccessAndNoReturnUrlGiven() and Put_ReturnsRedirectResultIfLogonSuccessAndReturnUrlGiven() test are not passing. I have narrowed it down to the line where i am calling _membership.validateuser(). Even though during my mock setup of the service i am stating that i want to return true whenever validateuser is called, the method call returns false.
Here is what I have gotten so far
AccountController.cs
[HandleError]
public class AccountController : Controller
{
private IMembershipService _membershipService;
public AccountController()
: this(null)
{
}
public AccountController(IMembershipService membershipService)
{
_membershipService = membershipService ?? new AccountMembershipService();
}
[HttpGet]
public ActionResult LogOn()
{
return View();
}
[HttpPost]
public ActionResult LogOn(LogOnModel model, string returnUrl)
{
if (ModelState.IsValid)
{
if (_membershipService.ValidateUser(model.UserName,model.Password))
{
if (!String.IsNullOrEmpty(returnUrl))
{
return Redirect(returnUrl);
}
return RedirectToAction("Index", "Overview");
}
ModelState.AddModelError("*", "The user name or password provided is incorrect.");
}
return View(model);
}
}
AccountServices.cs
public interface IMembershipService
{
bool ValidateUser(string userName, string password);
}
public class AccountMembershipService : IMembershipService
{
public bool ValidateUser(string userName, string password)
{
throw new System.NotImplementedException();
}
}
AccountControllerFacts.cs
public class AccountControllerFacts
{
public static AccountController GetAccountControllerForLogonSuccess()
{
var membershipServiceStub = MockRepository.GenerateStub<IMembershipService>();
var controller = new AccountController(membershipServiceStub);
membershipServiceStub
.Stub(x => x.ValidateUser("someuser", "somepass"))
.Return(true);
return controller;
}
public static AccountController GetAccountControllerForLogonFailure()
{
var membershipServiceStub = MockRepository.GenerateStub<IMembershipService>();
var controller = new AccountController(membershipServiceStub);
membershipServiceStub
.Stub(x => x.ValidateUser("someuser", "somepass"))
.Return(false);
return controller;
}
public class LogOn
{
[Fact]
public void Get_ReturnsViewResultWithDefaultViewName()
{
// Arrange
var controller = GetAccountControllerForLogonSuccess();
// Act
var result = controller.LogOn();

var redirectresult = (RedirectToRouteResult) result;

}
[Fact]
public void Put_ReturnsViewIfInvalidModelState()
{
// Arrange

controller.ModelState.AddModelError("*","Invalid model state.");
// Act
var result = controller.LogOn(user, "someurl");
var viewResult = (ViewResult) result;
// Assert
Assert.IsType<ViewResult>(result);
Assert.Empty(viewResult.ViewName);
Assert.Same(user,viewResult.ViewData.Model);
}
[Fact]
public void Put_ReturnsViewIfLogonFailed()
{
// Arrange
var controller = GetAccountControllerForLogonFailure();
var user = new LogOnModel();
// Act
