Hi I am trying to set up a unit test that has reference of membership.provider in it.  This is done in MVC3. 

I tried doing a couple things but I got no luck. 

On this accountcontroller, the Login Method goes through a large amount of logic. 

I tried this:

Mock.Arrange(() => Membership.Provider).Returns(fakeProvider);


where fakeprovider was Mock.Create<CustomMembershipProvider>();

It is always returning as null. 

I was able to get my unit test to make sure that it can check the logic of the !ModelState.IsValid, but I cannot seem to get the two bolded lines in the code below to return what I want it to return.

I tried to use the doinstead but I had to make the Arrange/ArrangeSet in a try/catch block. 

Is there something that I am missing that is making this always null. 

Any help would be greatly appreciate.  Thanks.

 

public ActionResult Login(AccountLogin accountLogin)
if (!ModelState.IsValid)
{
return View(accountLogin);
}
CustomMembershipProvider membershipProvider = Membership.Provider as CustomMembershipProvider;
MembershipUser user = membershipProvider.GetUser(accountLogin.UserName);
 
if (user != null && user.LastLoginDate.AddDays(180) < DateTime.Now)
{
      membershipProvider.LockUser(user.UserName);
ModelState.AddModelError("", inactivityLockedMessage);
return View(accountLogin);
 }
if (Membership.ValidateUser(accountLogin.UserName, AESCryptography.Encrypt(accountLogin.Password)))
      {
  // store single session ID
user.Comment = Guid.NewGuid().ToString();
Membership.UpdateUser(user);
public void Login_Where_ModelState_IsNot_Valid_test() //this unit test passes with no issue
{
var target = new AccountController();
var accountLogin = new AccountLogin();
var result = new ViewResult();
  
Mock.Arrange(() => target.Login(accountLogin)).OccursOnce();
//to make target.ModelState.IsValid return false
target.ModelState.AddModelError("key", "needs to be false");
  
result = (ViewResult)target.Login(accountLogin);
  
Assert.IsTrue(target.ModelState.IsValid == false);
Assert.IsTrue(result.ViewName == string.Empty);
Mock.Assert(target.Login(accountLogin));
}

 

 

 

 

[TestMethod]
public void Login_Where_Inactivity_is_Hit_test()
{
    string inactivityLockedMessage = "Your account is locked due to inactivity.  Please contact AI Portal support.";
       //Arrange
    controller = Mock.Create<AccountController>();
    accountLogin = new AccountLogin { UserName = "" } //string.empty;
    action = Mock.Create<ActionResult>(); 

    Mock.Arrange(() => controller.ModelState.IsValid).Returns(true);
    CustomMembershipProvider fakeProvider = Mock.Create <CustomMembershipProvider>();
    MembershipUser user = Mock.Create<MembershipUser>();
             
    bool called = false
    try
     {
     Mock.ArrangeSet(() => action = controller.Login(Arg.IsAny<AccountLogin>()))
     .DoInstead(() =>
     {
     Mock.ArrangeSet(() => user.LastLoginDate.AddDays(180));
     Mock.Arrange(() => user.LastLoginDate < DateTime.Now).Returns(true);
     controller.ModelState.AddModelError("", inactivityLockedMessage);
     called = true;
     })
     .Returns(action);
     }
     catch (NullReferenceException)
     {
    Mock.Arrange(() => fakeProvider.LockUser(accountLogin.UserName)).Returns(true);
    Mock.ArrangeSet(() => user.LastLoginDate.AddDays(180));
    Mock.Arrange(() => user.LastLoginDate < DateTime.Now).Returns(true);
    controller.ModelState.AddModelError("", inactivityLockedMessage);
    called = true;
     }
  
    //Assert 
    Mock.Assert(user.LastLoginDate);
    Mock.Assert(fakeProvider);
    Assert.IsTrue(called);
    Assert.IsFalse(controller.ModelState.IsValid);
    Assert.IsTrue(controller.ModelState.Count==1, "should not be more than 1 error");
    string modelerror = controller.ModelState[""].Errors[0].ErrorMessage;
    Assert.IsTrue(inactivityLockedMessage==modelerror, "should be equal");  
}

Hi Ewin,

 Thank you for reaching Telerik support.

 In order to help you further, I must object that you are using the JustMock Free edition, which does not support features using profiler. Without the profiler you are not able to mock static members/classes, which makes the correct execution of your test method difficult. You can find more about the Free and Commercial version of our product here:
 - http://www.telerik.com/help/justmock/getting-started-commercial-vs-free-version.html

 If there is anything else, I can help you with, please do not hesitate to ask.

Greetings,
