Mock property

Hi,

Yesterday, I tried to mock a property of an object to define the return value but it doesn't work. I know that I am two levels depth but can you explain me what is wrong with this code...

Public Interface IProcessor

Property Connection As IConnection

Function Execute() As Boolean

End Interface

Public Interface IConnection

Function Open() As Boolean

End Interface

Public Class DatabaseExecutor

Implements IProcessor

Public Property Connection As IConnection Implements IProcessor.Connection

Public Function Execute() As Boolean Implements IProcessor.Execute

If Me.Connection.Open Then

Return True

Else

Return False

End If

End Function

End Class

Imports NUnit.Framework

Imports Telerik.JustMock

<TestFixture()>

Public Class DatabaseExecutorTests

''' <summary>

''' This test fail because I try to mock the function open of the objet IConnection directly

''' from the property Connection of the object Processor.

''' </summary>

''' <remarks></remarks>

<Test()>

Public Sub Execute_SimpleRequest_ReturnsTrue()

Dim executor As New DatabaseExecutor

executor.Connection = Mock.Create(Of IConnection)()

Mock.Arrange(Function() executor.Connection.Open).Returns(True)

Assert.AreEqual(True, executor.Execute)

End Sub

''' <summary>

''' This test pass because I create the connection separatly of the Processor objet and then

''' assign it to the property Processor.

''' </summary>

''' <remarks></remarks>

<Test()>

Public Sub Execute_SimpleRequestViaProperty_ReturnsTrue()

Dim executor As New DatabaseExecutor

Dim connection As IConnection = Mock.Create(Of IConnection)()

Mock.Arrange(Function() connection.Open).Returns(True)

executor.Connection = connection

Assert.AreEqual(True, executor.Execute)

End Sub

End Class

If you want, I can send you a demo but I think this will be very easy question for you.

Debugging test

Hi,

In Visual Studio, my shortcut to "Step into" while I'm debugging is F8.

When I'm into a test in debug mode and I press F8 to step into and when I'm on a line like Mock.Arrange or any other instruction using JustMock, the system is trying to enter in the code of JustMock.

In my visual studio, I have enable just my code in debugging options.

I have no problem with any other third party control in the sens that F8 don't try to step into the code of the third party.

It's very weird.

Here is what it show in the immediate when I press F8 on a line with JustMock instruction:

Step into: Stepping over non-user code 'System.Linq.Expressions.Expression.Constant'
A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll
Step into: Stepping over non-user code 'Telerik.JustMock.Mock.<bool>.'

Public Sub Execute_SimpleRequest_ReturnsTrue()

Dim executor As New DatabaseExecutor

executor.Connection = New Connection

Mock.Arrange(Function() executor.Connection.Open).Returns(True)

Assert.AreEqual(True, executor.Execute)

End Sub

These messages are shown on the line Mock.Arrange....

The reason why I use Step into instead of Step over is just because I want systematically to enter in any functions of my code. Remember before answering that I have no problem with other third party like your, Infragistics, DevExpress, ActiveReports, etc...

Thank you very much.

Mocking OpenAccess

To be honest I haven't really tried JustMock as of yet, but we've recently ran into some issues with OpenAccess where some updates have broken some functionality...

So as I understand it, the Mocking tool can "Fake" a database?

Is it possible to write some tests to create an OA object, then commit that object, but the database end is handled by JustMock?

Is that how this all works together? :)

System.TypeAccessException

Hi, I'm trying to evaluate JustMock for the team. Trying to convert some Moq tests to JustMocks and I'm getting an error like:

Test method Implementation.Test.HealthCheckHandlerTest.active_endpoints_returns_results_using_JustMock threw exception:
System.TypeAccessException: Attempt by method 'PrivateApiProxy_Interceptor_38cce20ce0d04bd6b91832ef4a05927c.Intercept(Implementation.PrivateApiAccess.PrivateApiProxy, Boolean ByRef)' to access type 'System.Collections.Generic.IEnumerable`1<Implementation.PrivateApiAccess.PrivateApiResponse>' failed.

Strangely, although I initialized them as strict, the calls seem to be falling through into the implementation.

I'm in a bit of a hurry, so I've simply remove some of the namespaces to protect the inocent. Can you tell me what I might be doing wrong to recieve this error. I may be able to write something stand alone that I can share, but it is annoying when you get an unhandle exception from the framework.

Getting JustMock to run on a build server

Hi,

I'm trying out the JustMock and getting it up and running on my local dev box (Windows 7 x64) with VS 2010 installed was no problem. However, I'm having problem getting the tests to run on our Windows 2003 build server where there's no VS installed.

I have added the <Import ...> and <JustMockStart> + <JustMockStop> in my build script, but it seems like the CLR profiler won't start when running on the build server. Am I missing something? Do I need to download and install CLR Profiler for .Net 2.0 (http://www.microsoft.com/downloads/en/confirmation.aspx?FamilyID=a362781c-3870-43be-8926-862b40aa0cd0&displaylang=en) on the build server? Or is VS required?

Why does this not work as expected?

Please see the narrowed down code-example below.

What I expect is the method IsElf() to return a value of TRUE.
When I debug the UnitTest, mensMock.Leeftijd returns a value of 11. When I look at the value of actual, it's value = false???
It seems that the Mock object is not 'routing' the call as expected...

When I use the Behaviour.CallOriginal setting (which is not documented BTW) when Creating the Mock everything works as expected. Loose and Strict mode both fail.

I really like your concept of mocking, could you please tell me what I'm doing wrong?

Kind regards from Holland & TIA,

Ronald.

Mocking SharePoint SPSecurity.RunWithElevatedPrivileges

Hi,

is there any way to mock the the call to SPSecurity.RunWithElevatedPrivileges delegate, e.g.

...

SPSecurity.RunWithElevatedPrivileges(delegate()

{

// Code to unit test

});

...

Basically, I'd like to test the code passed as an anonymous delegate to the SPSecurity.RunWithElevatedPrivileges(), but am not able to mock the call to the SPSecurity.RunWithElevatedPrivileges() to simply bypass SharePoint and just execute whatever is passed in.

Any suggestions?

Regards, Robert

Mocking final methods

I seem to be having problems with mocking final methods (or any other elevated features). even running the examples fails. Take the following for instance...

[TestMethod]

public void ShouldTreatSetupsForTwoDifferentInstancesDifferently()

{

var foo1 = Mock.Create<Foo>();

var foo2 = Mock.Create<Foo>();

Mock.Arrange(() => foo2.Echo(Arg.IsAny<int>())).Returns(10);

Mock.Arrange(() => foo1.Echo(Arg.IsAny<int>())).Returns((int arg) => arg);

Assert.Equal(foo2.Echo(12), 10);

Assert.Equal(foo1.Echo(12), 12);

}

I expect both of these asserts to return true but the first fails as the call to echo returns 36. I have the 'advanced' features turned on from the justmock menu (VS2008SP1) but no matter what I try it just wont pass.

Any help greatly appreciated,

Leom

Assert() and Arrange()

Hello,

I got a question or sort of functionallity request.
After a little while working with JustMock, I found out that the Assert(action) communicates with Arrange(action).

I will show you a sample of how the code works how it is now

//Arrange

Mock.Arrange(() => _mock.ThisIsAMethod(module, moduleSetting1.Name)).Returns(moduleSetting1.Value).MustBeCalled();

Mock.Arrange(() => _mock.ThisIsAMethod(module, moduleSetting2.Name)).Returns(moduleSetting2.Value).MustBeCalled();

Mock.Arrange(() => _mock.ThisIsAMethod(module, moduleSetting3.Name)).Returns(moduleSetting3.Value).MustBeCalled();

//Act

_presenter.Load();

//Assert

Mock.Assert(() => _mock.ThisIsAMethod(module, moduleSetting1.Name), Occurs.Exactly(1));

Mock.Assert(() => _mock.ThisIsAMethod(module, moduleSetting2.Name), Occurs.Exactly(1));

Mock.Assert(() => _mock.ThisIsAMethod(module, moduleSetting3.Name), Occurs.Exactly(1));

Well in the sample I got 3 module settings but in the real code i got like 12. Now I want to validate how much times it is cast with 1 code rule not 12. I thougth about the below solution but it always says it has been called once.

//Arrange

Mock.Arrange(() => _mock.ThisIsAMethod(module, moduleSetting1.Name)).Returns(moduleSetting1.Value).MustBeCalled();

Mock.Arrange(() => _mock.ThisIsAMethod(module, moduleSetting2.Name)).Returns(moduleSetting2.Value).MustBeCalled();

Mock.Arrange(() => _mock.ThisIsAMethod(module, moduleSetting3.Name)).Returns(moduleSetting3.Value).MustBeCalled();

//Act

_presenter.Load();

//Assert

Mock.Assert(() => _mock.ThisIsAMethod(module, Arg.AnyString), Occurs.Exactly(3));

This woulth be a good solution because it saves me a lot of code. Hope this is possible some how or will be possible in the next update.

Thanks in advance,
Jeroen Speldekamp

Tests using Static mocking failing on Build Server

Hi,

We're using TFS2010, and we think we've installed JustMock correctly on the server, but everytime we run the build any test using the Static mocking is failing and everything else passes.

The documentation only seems to deal with the 2008 build scripts, is there a 2010 version anywhere?

Thanks,
John
