Failure of recursive mocking of internal type.

I think I have discovered a bug.

internal class InternalClass

{

public int GetInt() { return 5; }

}

internal class InternalOwner

{

public int GetInt() { return 5; }

public InternalClass InternalClassField = new InternalClass();

public InternalClass InternalClassProp

{

get { return InternalClassField; }

}

...

[Test]

public void Test5()

{

InternalOwner io = Mock.Create<InternalOwner>();

// Mock.Arrange(() => io.GetInt()).Returns(6); // Test1, works.

// Mock.Arrange(() => io.InternalClassField.GetInt()).Returns(6); // Test2, works.

Mock.Arrange(() => io.InternalClassProp.GetInt()).Returns(6); // Test3, FAILS.

}

If you uncomment each of the lines Test1, Test2 and Test3 in turn you'll see that recursively mocking the GetInt() method via InternalClassProp fails.

Adding the InternalsVisibleto assembly attribute has no effect.

Tests failing when mocking a type same as the type under test

Hi,

I'm using JustMock Q1 2012 SP1 (2012.1.508.6) and when I try to create a mock of the same type as the one under test most of the test for the type are failing.

A simplified example of what I'm doing follows.
var mock = Mock.Create<MyTypeUnderTest>(Constructor.Mocked);
var target = new MyTypeUnderTest ();
target.TestMethod();

The only temporary solution I've found is to create the Mock with Behavior.CallOriginal.

Any solution for this?

Kind Regards,
Edoardo

Mock Thread fails

I'm using JustMock Q1 2012 SP1 (2012.1.508.6) and when I try to create a mock of the Thread class, I get an exception.

I tried the following methods:

- var mock = Mock.Create<Thread>.Create(any argument);
- var mock = Mock.Create<Thread>.Create(new Thread(delegate{}));

Both fails whether I use the MockClass attribute or not.

Any suggestion?
Thanks.

Mocked Test Failing

I'm trying to test a method that simply looks to see if a value exists in a property that contains a list of strings, but the test fails despite the fact that the value is in the list. Here is some sample code:

Imports System.Text

Imports Telerik.JustMock

Public Class User

Public Sub New()

MyBase.New()

End Sub

Public Shared Function Create() As User

Dim returnValue As New User

returnValue.UID = "TestUser"

returnValue.Roles.Add("Admin")

Return returnValue

End Function

Public Property UID As String

Public Property Roles As List(Of String)

Public Function IsAdministrator() As Boolean

Return _roles.Contains("Admin")

End Function

End Class

<TestClass()>

Public Class Mocking

<TestMethod()>

Public Sub Works()

Dim user As User = user.Create

Assert.IsTrue(user.IsAdministrator)

End Sub

<TestMethod()>

Public Sub DoesNotWork()

Dim user As User = Mock.Create(Of User)()

Dim roles As New List(Of String)

Mock.Arrange(Function() user.UID).Returns("SomeUser")

roles.Add("Admin")

Mock.Arrange(Function() user.Roles).Returns(roles)

Assert.AreEqual("SomeUser", user.UID)

Assert.AreEqual(roles.Count, user.Roles.Count)

Assert.AreEqual("Admin", user.Roles.Item(0))

Assert.IsTrue(user.IsAdministrator)

End Sub

End Class

I'm sure I'm just missing something obvious, so any help is greatly appreciated.

GUID list changes after mocked

Hi..

I have this kind of test situation I need Guid list to be send with ReturnsCollection

[TestMethod]
public void GetCodedObjectsClients_WithServiceArea()
{
// Arrange
KAPRole role = CreateDataRole();

//Create test worker
OHPClientWorker clientWorker = new OHPClientWorker(Entities);
Guid MyGuidi = new Guid("ccae2079-2ebc-4200-879d-866fc82e6afa");
Guid MyGuidi2 = new Guid("ccae2079-3ebc-4200-879d-866fc82e6afa");
IEnumerable<Guid> guids = new List<Guid> { MyGuidi, MyGuidi2 };

// Create mock data
Mock.Arrange(() => clientWorker.ServiceAreaWorker.GetServiceAreaUserGuids(Arg.IsAny<long>())).ReturnsCollection(guids);

But in code to test the Guid list contains only guids 00000 0000 00000 00000 .... So guid was changed from ccae2079-2ebc-4200-879d-866fc82e6afa" to 00000 0000 00000 0000 Why

public ICollection<OHPClientWithCodedObject> GetCodedObjectsClients(ICollection<long> objectIDs, ICollection<KAPRole> roles, long serviceAreaID)
{
//Users with rights granted through servicearea
ICollection<Guid> userGuids = ServiceAreaWorker.GetServiceAreaUserGuids(serviceAreaID);
............
userGuids  does not contain anymore real Guids

Any Idea why ReturnsCollection  chages Guids

StrongNameKeyPair

We recently had a need to start using Telerik JustMock to go along with the other telerik products we are using. Upon installation and running the sample Mock code we ran into exception setting up Mock classes "Unable to obtain public key for StrongNameKeyPair". We're running on Windows 7 x64. After hunting around in the forums and net for possible solutions, I noticed other Mocking software having similar type problems on Windows 7 x64. It turns out if we open up the security on the "C:\users\all users\microsoft\crypto\rsa" folder (Read &execute / List Folder/ Read/ Write) it resolves the issue.

Is there a better workaround that we could be using, or atleast a change in the installer so the security permissions get updated properly? or better yet, a different solution that I missed?

Can't arrange method call on different object of same type after invocation.

I have an odd case where I have multiple tests running on the same class. For most of these tests I am mocking a method on the class to return controlled results. One of the tests actually uses the normal version of the method. When the test that uses the concrete version of the method call runs first then I am unable to mock the method in the other tests.

Here is some example code depicting my issue:

var first = new MyClass();

var second = new MyClass();

second.DoSomething();

Mock.Arrange(() => first.DoSomething()).Returns(new List<IDataItem>);

first.DoSomething();

In the code above, first will actually call the method rather than using the mock. Is this a bug? It seems like a bug. Is there a work around?

Mock Extension Method Throws "Object reference not set to an instance of an object."

I am simply trying to mock an extension method on an Enum and no matter how I set it up I always seem to get a "Object reference not set to an instance of an object." error. Here is my code:

var invalidType = new

MyEnum();

Mock.Arrange(() => invalidType.ToType()).Returns((System.Type)

null);

The extension method (ToType) is just a switch statement that maps enum values to Types. I also tried using a mock for the invalidType.
