Static Mock Help

Hey everyone,

I am trying to do some static mocking. here is my test.

[Test]

public void timesheet_processor_tests_just_mock()

{

Mock.SetupStatic(typeof(LaborManager));

Mock.Arrange(() => LaborManager.GetTimesheetLabor(DateTime.Now, 1683)).Returns(new TimesheetLaborReadOnlyCollection());

var processor = new TimesheetProcessor();

processor.ProcessUserTimesheet(DateTime.Now, 1683);

Mock.Assert(() => LaborManager.GetTimesheetLabor(DateTime.Now, 1683), Occurs.AtLeastOnce());

}

The class TimesheetProcessor uses LaborManager.GetTimesheetLabor() method which I have setup to return a new Collection which by Default would have a count == 0.

However, when I step into this and get into the TimesheetProcessor class where LaborManager.GetTimeSheetLabor() method is called. the variable laborEntries which calls the method I arranged in my test gets set to null instead of a new collection. Please see the timesheet processor code below

//Timesheet Processor Class

public void ProcessUserTimesheet(DateTime weekEndingDate, int userId)

{

TimesheetsCreated = new List<int>();

TimesheetLaborReadOnlyCollection laborEntries = LaborManager.GetTimesheetLabor(weekEndingDate, userId);

if(laborEntries.Count > 0)

ProcessTimesheetLaborUser(userId, weekEndingDate, laborEntries);

}

Why is this happening?
Have I setup my test incorrectly?

I have JustMock enabled.

Thanks,

-zd

Mock Property Set in VB.Net Module

Does anyone any ideas on how to mock a static property in a Vb.Net module?

I have attempted various solutions, all of which lead to JustMock throwing exceptions.

I am looking for something like:

Mock.ArrangeSet(Sub() VbModule.MyProperty = Arg.AnyString).DoNothing()
 




Any help would be appreciated.

Mock Registry.GetValue

I am attempting to mock Registry.GetValue with specific parameters using the following code:

Mock.Arrange(Function() Registry.GetValue("HKEY_CURRENT_USER\Software\VB and VBA Program Settings\Legacy App\Options", "SettingValue", String.Empty)).Returns("Test Result")

I get the following exception:

{"Object reference not set to an instance of an object."}

In the words of Julie Andrews ...

... let's start at the very beginning.

First, I want to apologise for a posting that it only loosely based on JustMock.

I have never written a unit test in my life and thought, given that I have access to JustMock, that I should give it a go and that's why I need help.

I'll explain.

I'm running VS2K8SP1 under Win7 Ultimate to develop Web Sites and Wep Applications.

I've done a bit of reading and have created a Test Project with a Test Method. My reading has led me to understand that I need to decorate my Test Method like this...

[TestMethod]

[HostType("ASP.NET")]

[UrlToTest("http://localhost:50612/TestBed/Default3.aspx")]

Trying to run this test resulting in a fail with the message ...

The test or test run is configured to run in ASP.NET in IIS, but the current user (Tosh-Laptop\Stuart) is not in the Administrators group. Running tests in ASP.NET in IIS requires the user to be in the Administrators group.

The thing is, I am in the Administrators group. The output from the command net localgroup Administrators confirms this ...

C:\Users\Stuart>net localgroup Administrators

Alias name Administrators

Comment Administrators have complete and unrestricted access to the compu

ter/domain

Members

-------------------------------------------------------------------------------

Administrator

Stuart

The command completed successfully.

So, I guess I'm missing something. Is anyone here running tests under a similar environment? Is anyone here better versed in what's needed to get me running.

Any help, either here, or - if you feel the response too off-topic for posting here - direct to me at sejhemming@gmail.com would be much appreciated.

Documentation error?

This refers to both the installed and online version of the docs.

If you go to figure 6 of this page you will see that includes a reference to the method Mock.CreateInstance<>().

Now, I've really only just started playing with JM, but I think that is is wrong.

mscorlib mocking without access to instance

The example, in the documentation, for mocking mscorlib types assumes that you have direct access to the object you want to mock from the unit test. However, I'm trying to mock a filesystem scenario and the code that I'm testing creates its own instance of the DirectoryInfo type that I want to mock.

Here's what my code looks like:

public class TypeBeingTested

{

public TypeBeingTested()

{

var folder = new DirectoryInfo("C:\\Program Files");

var folders = folder.GetDirectories("Microsoft Visual Studio 8");

if (folders.Length == 0)

throw new DirectoryNotFoundException("Visual Studio 2005 is not installed.");

}

I want to test the scenario where the Visual Studio folder cannot be found on my disk. The way I thought I could do this, looks like this:

[TestInitialize]

public void Mock_DirectoryInfo()

{

Mock.Partial<DirectoryInfo>().For<string>((folder, name) => folder.GetDirectories(name));

}

[TestMethod]

[ExpectedException(typeof(DirectoryNotFoundException))]

public void Missing_Program_Files_folder_throws_exception()

{

var folder = new DirectoryInfo("C:\\Program Files");

Mock.Arrange(() => folder.GetDirectories("Microsoft Visual Studio 8")).Returns(new DirectoryInfo[] {});

var instance = new TypeBeingTested();

Assert.Fail("No exception was raised in TypeBeingTested constructor.");

}

Obviously, that instance of "folder" in my test method isn't being used for anything other than the Arrange statement... I knew as I was writing that, that this wasn't going to work; but, I can't figure out how this test should be constructed.

Can anyone help?

Thanks!

Mocking a static method in Silverlight

I’m getting the following error when trying to mock a static function in a silverlight unit test:

“There were some problems intercepting the mock call. Optionally, please make sure that you have turned on JustMock's profiler while mocking concrete members.”

I don’t get the error in a full .NET unit test project, so, I wondered whether I was missing a setting or something?

My code from my silverlight unit test project is below. I get the error on the Mock.Arrange() line

Imports Microsoft.VisualStudio.TestTools.UnitTesting

Imports Telerik.JustMock

<TestClass()> _

Public Class Tests

<TestMethod()> _

Public Sub SharedMethodMustBeCalled()

Mock.Arrange(Function() SharedStuff.GetSomething(Arg.AnyString)).MustBeCalled()

Dim SomeClass As New SomeClass

Dim ret As String = SomeClass.DoSomething()

Mock.Assert(SomeClass)

End Sub

Public Class SomeClass

Public Function DoSomething() As String

Dim ret As String = SharedStuff.GetSomething("fred")

Return ret

End Function

End Class

Public Class SharedStuff

Public Shared Function GetSomething(ByVal Name As String) As String

Return "test"

End Function

End Class

Converting Rhino Mock code to JustMock

Could you help me convert this Rhino Mock code to JustMock?

[Test]

MockRepository mocks = new MockRepository();
IWebService simulatedService =
MockRespository.DynamicMock<IWebService>();
using(mocks.Record())
{
//we expected "Filename too short:abc.ext"
simulatedService.LogError("bad string");
}
LogAnalyzer log = new LogAnalyzer(simulatedService);
string tooShortFileName="abc.ext";
log.Analyze(tooShortFileName);

Mock.Arrange with dictionary parameter

I can't seem to get Mock.Arrange working with a dictionary parameter. I've included some sample code below. I was expecting ret to be equal to "test" but it is coming back as nothing. Have I got the syntax wrong in the Mock.Arrange() call?

<TestClass()> _

Public Class MyTests

<TestMethod()> _

Public Sub GetValue_ValueReturnedFromDatabase()

Dim ds As IDataService = Mock.Create(Of IDataService)()

Mock.Arrange(Function() ds.GetValue(Arg.AnyString, Arg.IsAny(Of Dictionary(Of String, Object)))).Returns("test")

Dim l As New LD(ds)

Dim ret As String = l.GetValue("xxx")

Assert.AreEqual("test", ret)

End Sub

End Class

Public Interface IDataService

Function GetValue(ByVal SQL As String, ByVal Params As Dictionary(Of String, Object)) As String

End Interface

Public Class DS

Implements IDataService

Public Function GetValue(ByVal SQL As String, ByVal Params As Dictionary(Of String, Object)) As String Implements IDataService.GetValue

Return "anything"

End Function

End Class

Public Class LD

Private _DataService As IDataService

Public Sub New(ByVal DataService As IDataService)

_DataService = DataService

End Sub

Public Function GetValue(ByVal Name As String)

Dim params As New Dictionary(Of String, Object)

Dim ret As String = _DataService.GetValue("Some SQL", params)

Return ret

End Function

End Class
