Hi,
I'm having trouble when mocking methods from VirtualPathUtility class, i.e.VirtualPathUtility.ToAbsolute(...)

Here is a test sample :

    public class XTest
    {
        static XTest()
        {
            Mock.Replace(() => System.Web.VirtualPathUtility.ToAbsolute(Arg.AnyString)).In<XTest>(x => x.Test());
        }

        [Fact]
        public void Test()
        {
            Mock.SetupStatic(typeof(System.Web.VirtualPathUtility));
            Mock.Arrange(() => System.Web.VirtualPathUtility.ToAbsolute(Arg.AnyString)).Returns("absolute");

            string r = System.Web.VirtualPathUtility.ToAbsolute("test");

            Assert.Equal("absolute", r);
        }
    }

I've also tried using Mock.Initialize, Mock.Replace is static constructor but didn't help.
I'm always getting exception:

System.IO.FileNotFoundException : Could not load file or assembly 'Telerik.CodeWeaver.Api, Version=1.0.0.0, Culture=neutral, PublicKeyToken=87210992829a189d' or one of its dependencies. The system cannot find the file specified.

Any idea what am I doing wrong?

Thanks

Heiko

EntityFramework mocking: ObjectContext.Dispose() throwing FileLoadException.

Hi.

I recently downloaded a sample project from this thread and it worked fine.

So, I started to make some modifications, adding this simple test method to the JustMockTest1 class:

[TestMethod]

public void ShouldAssertMockedGetAllCategories()

{

NorthwindEntities entities = Mock.Create<NorthwindEntities>();

Category category = new Category()

{

CategoryName = "Beer"

};

List<Category> allCategories = new List<Category>

{

category

};

// Arrange

Mock.Arrange(() => entities.Categories).ReturnsCollection(allCategories);

// Act

List<Category> categoriesList= entities.Categories.ToList();

// Assert

Assert.AreEqual(1, categoriesList.Count);

Assert.AreSame(category, categoriesList[0]);

}

Again, everything worked like a charm.

Since I don't access a ObjectContext directly I tried to make things a little bit real world like.

[TestMethod]

public void ShouldAssertMockedGetAllCategories()

{

NorthwindEntities entities = Mock.Create<NorthwindEntities>();

Category category = new Category()

{

CategoryName = "Beer"

};

List<Category> allCategories = new List<Category>

{

category

};

// Arrange

Mock.Arrange(() => entities.Categories).IgnoreInstance().ReturnsCollection(allCategories);

// Act

//Some instance of some class calls the following lines of code somewhere, somehow. =)

NorthwindEntities ne = new NorthwindEntities();

List<Category> categoriesList = ne.Categories.ToList();

// Assert

Assert.AreEqual(1, categoriesList.Count);

Assert.AreSame(category, categoriesList[0]);

}

Test passed. \o/

Oops! I forget to call Dispose(). Let's first try the default way to do that.

[TestMethod]

public void ShouldAssertMockedGetAllCategories()

{

NorthwindEntities entities = Mock.Create<NorthwindEntities>();

Category category = new Category()

{

CategoryName = "Beer"

};

List<Category> allCategories = new List<Category>

{

category

};

// Arrange

Mock.Arrange(() => entities.Categories).IgnoreInstance().ReturnsCollection(allCategories);

// Act

//Some instance of some class calls the following lines of code somewhere, somehow. =)

List<Category> categoriesList;

using (NorthwindEntities ne = new NorthwindEntities())

{

categoriesList = ne.Categories.ToList();

}

// Assert

Assert.AreEqual(1, categoriesList.Count);

Assert.AreSame(category, categoriesList[0]);

}

Uh-oh. An Exception was thrown at the end of using block.

Even if I call Dispose() directly (instead of using the using statement), test fails for the same reason.

[TestMethod]

public void ShouldAssertMockedGetAllCategories()

{

NorthwindEntities entities = Mock.Create<NorthwindEntities>();

Category category = new Category()

{

CategoryName = "Beer"

};

List<Category> allCategories = new List<Category>

{

category

};

// Arrange

Mock.Arrange(() => entities.Categories).IgnoreInstance().ReturnsCollection(allCategories);

// Act

//Some instance of some class calls the following lines of code somewhere, somehow. =)

NorthwindEntities ne = new NorthwindEntities();

List<Category> categoriesList = ne.Categories.ToList();

ne.Dispose();

// Assert

Assert.AreEqual(1, categoriesList.Count);

Assert.AreSame(category, categoriesList[0]);

}

Am I missing something here?

Thanks in advance.

JustMock on TFS 2010 Build not running tests.

I've completed the instructions in the document on configuring Telerik.JustMock.Build.Workflow into our Build Template but unfortunately the build process no longer runs the tests. It just outputs 'No Test Results'. I've even went into the Test.csproj and added the before and after test and added the JustMock targets like the instructions for MSBuild state.

Anyone seen this before?

Thanks,
Jason

What am I doing wrong?

Here is a unit test setup that I am having issues with.... This code exists within a class called TestBase which my unit test classes inherit from....

#region Mocked Members

protected HardCodedSiteOptionsEntity Target;

protected IDependencyInjection InjectorMock;

protected IMessageOperations MessageMock;

#endregion

[SetUp]

public void InitializeBase()

{

Target = Mock.Create<HardCodedSiteOptionsEntity>(Behavior.CallOriginal);

InjectorMock = Mock.Create<IDependencyInjection>();

MessageMock = Mock.Create<IMessageOperations>();

Target.Arrange(mockedObject => mockedObject.MessageOperationsHelper).Returns(MessageMock);

//Target.MessageOperationsHelper = MessageMock;

}

The issue I am having is when I have the code setup as shown I recieve a NullReferenceException on the Target.Arrange method.... I am using the Q3 release of JustMock.

When I comment out the Target.Arrange line and uncomment the line afterwards, it seems to work as expected.
Here is a snippet of the Target( class under test)

internal class HardCodedSiteOptionsEntity : ISiteOptions, IBlockEntityPartBuilder<uint>

{

#region Internal Properties

internal virtual BitArray StatusMaskData { get; set; }

internal virtual IDependencyInjection InjectorHelper { get; set; }

internal virtual IMessageOperations MessageOperationsHelper { get; set; }

#endregion

#region Constructor

internal HardCodedSiteOptionsEntity()

{

InjectorHelper = new DependencyInjector();

MessageOperationsHelper = InjectorHelper.InjectEntity<IMessageOperations>();

StatusMaskData = new BitArray(32, false);

}

I have InternalsVisibleTo attribute set in my assemblyinfo.cs so the internal visibility shouldn't be causing the issue....

Error while trying to run justmock sample

Hi,

Intercepting Membership.Provider

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");

}

static class File

I'm having trouble mocking File.WriteAllBytes. Here's my test code:

var called = false;

var ccr = new Ccr { Pdf = new byte[73], SubmissionId = 3 };

Mock.Replace<string, byte[]>((s, b) => File.WriteAllBytes(s, b)).In<CcrFileWriter>(x => x.WriteToDisk(ccr));

Mock.Arrange(() => File.WriteAllBytes(null, null)).IgnoreArguments().DoInstead(()=> called = true);

var writer = new CcrFileWriter();

writer.WriteToDisk(ccr);

Assert.IsTrue(called);

It's not working. It's not bypassing File.WriteAllBytes and the test fails.
Maybe I'm not understanding how this should work?

Mocked Method not returning correct object

I have a unit test that is attempting to test a very simple method. The method under test simply calls two other methods (interface methods that are marked as virtual in the implementation). I use the following code in the unit test....

IEnumerable<byte> passedMessage1 = new byte[16];

Mock.Arrange(() => MessageOperationsMock.InsertNetworkAddressIntoMessage

(Target.PrimaryReportingAddress, passedMessage1, 3))

.DoNothing()

.Returns(passedMessage1)

.OccursOnce();

Mock.Arrange(() => MessageOperationsMock.InsertNetworkAddressIntoMessage

(Target.AlternateReportingAddress, passedMessage1, 25))

.DoNothing()

.Returns(passedMessage1)

.OccursOnce();

Target.PrimaryReportingAddress = LocalTestScenarios.TestIPAddress1;

Target.AlternateReportingAddress = LocalTestScenarios.TestIPAddress2;

Target.InsertNetworkAddressesIntoPart(passedMessage1);

Mock.Assert(MessageOperationsMock);

The Target method is....

internal virtual IEnumerable<byte> InsertNetworkAddressesIntoPart(IEnumerable<byte> messageBeingCreated)

{

messageBeingCreated = MessageOperationsHelper.InsertNetworkAddressIntoMessage(PrimaryReportingAddress, messageBeingCreated, 3);

messageBeingCreated = MessageOperationsHelper.InsertNetworkAddressIntoMessage(AlternateReportingAddress, messageBeingCreated, 25);

return messageBeingCreated;

}

and here is the mocking setup....

protected HardCodedMonitoringSettingsEntity Target;

protected IDependencyInjection InjectorMock;

protected IValidationOperations ValidatorMock;

protected IMessageOperations MessageOperationsMock;

[SetUp]

public void InitializeBase()

{

Target = Mock.Create<HardCodedMonitoringSettingsEntity>(Behavior.CallOriginal);

InjectorMock = Mock.Create<IDependencyInjection>();

ValidatorMock = Mock.Create<IValidationOperations>();

MessageOperationsMock = Mock.Create<IMessageOperations>();

Target.DependencyInjector = InjectorMock;

Target.ValidationOperationsHelper = ValidatorMock;

Target.MessageOperationsHelper = MessageOperationsMock;

}

The problem is the test says that expected called once but was called 0 times. What I see when I debug the code is that my passedMessage variable goes from a byte array to some other type of object (goes from saying byte[16] to count = 0 after the first method is called.

Any thoughts?
