Using DoInstead for a private method

Hi I have this situation.

Public Class PrivateMethodDoInstead

Private Function GetSomeQuantity(ByRef quantity As Long) As Boolean

'....get quantity from the database code would be here

Return quantity > 0

End Function

Public Function HandleRecords() As Boolean

Dim quantity As Long

Dim returnValue As Boolean = GetSomeQuantity(quantity)

If returnValue Then

StoreTotals(quantity)

End If

Return returnValue

End Function

Private Sub StoreTotals(quantity As Long)

' do something

End Sub

End Class

I would like to Mock my private function GetSomeQuantity.
It is private. When it is public it would work by doing this:

Mock.Arrange(Function() testInstance.GetSomeQuantity(

Arg.IsAny(Of Long))

).DoInstead(Function(ByRef quantity As Long) As Boolean

quantity = 5

Return True

End Function).Returns(True)

But how can I do this for a private function?
I did try it using the nonpublic, but it keeps giving me an error that it cannot resolve the method and that I should check my arguments.

Any help would be appreciated.

Thanks,

Wietze

JustMock support on Mono

I had a first try with JustMock on a Linux build machine (Jenkins) and xunit (Mono 4.6 is installed there). Unfortuntely, I get the following exception (one of them):

01.

Is this scenario supported on Linux/Mono at all? Can I do something to make this work?

Thanks, Ioan

Sequential mocking (ReturnsMany) does not work

For some reason, the ReturnsMany method does not work for me. I have the follwing code:

List<ORGANIZATION> existingOrganizations = new List<ORGANIZATION>()

{

new ORGANIZATION() {ID = 1, NAME = "Organization1", ISINCLUDEDINSAMPLE = false},

new ORGANIZATION() {ID = 2, NAME = "Organization2", ISINCLUDEDINSAMPLE = false},

new ORGANIZATION() {ID = 3, NAME = "Organization3", ISINCLUDEDINSAMPLE = false},

};

container.Arrange<IOrganizationRepository>(or => or.GetById(Arg.AnyLong)).ReturnsMany(existingOrganizations);

And the exception I'm getting:

System.InvalidCastException : Unable to cast object of type 'System.Collections.Generic.List`1[Cpims.WFM.Domain.Organizations.ORGANIZATION]' to type 'Cpims.WFM.Domain.Organizations.ORGANIZATION'.

at Castle.Proxies.IOrganizationRepositoryProxy.GetById(Int64 primaryKey, Expression`1[] includeNavigationProperties)

Mocking Encoding.UTF8.GetBytes throws NotImplementedException

Trying to arrange Encoding.UTF8.GetBytes to return some bytes is throwing an NotImplementedException with the message "You can't call the original implementation of a method that does not have one (abstract or interface method). I'm able to successfully mock out Encoding.UTF8.GetString in the exact same way, so this confuses me. Is it a bug?

Why is the Enable/Disable the profiler an IDE setting?

Hi.
I am slightly confused by the JustMock integration with visual studio.

Will tests start failing if I disable the "Enable Profiler" setting?
How do I control this setting on the CI build server?

It seems to me that wether or not the JustMock library shall use the .NET profiler API should be an attribute or passed parameter in the individual test and not a global IDE setting. Then I should organize my tests so that I don't run long-running ones on the quick cycles.
The profiler should be dynamically loaded if the unit tests demanded the profiler. AFAICT, this information should be contained in the unit tests.

Why was the approach chosen to have this as a manual setting in the IDE? I want my testcode to be self specified. I don't want to explain to a colleague that the reason why my unit tests are failing on his computer is because of a setting. That's a definite no-no in TDD.

Why was this approach chosen?

Asserting that return was called after condition met in void type method

In a method like

void ReturnIfObjectIsNull()

{

var obj = new SomeObject();

if (obj == null)

return;

// Do other stuff..

}

How do I assert that the early return fired (without asserting that the stuff that would have happened afterword never occurred).
Asserting the object is null is not enough. I would need to assert that he function returned early when the object was null.

Thanks.

Moking HttpWebRequest & HttpWebResponse

Hi,

I am new to justmock and need help in mocking the below code.I have a WCF data service method which process the service URI and gives out a XML result. I am not sure on how to mock the HTTP request and response, especially assigning content type etc.Can anybody help out with below.Thanks in advance.

// Obtain an HTTP web Request object for the desired URI

var Request = WebRequest.Create(strUri) as HttpWebRequest;

if (Request != null)

{

Request.KeepAlive = false;

Request.Method = "GET";

Request.ContentType = "application/ems-v3+xml";

// Obtain the HTTP web response

using (var Response = Request.GetResponse() as HttpWebResponse)

{

// Read the response text stream (the XML) into a local string

if (Response != null)

using (var ResponseStreamReader =

new StreamReader(Response.GetResponseStream()))

{

//get XML Result

result = ResponseStreamReader.ReadToEnd();

}

Thanks,
Divya

ArrangeSet() Assert Bug When Referring To Same Subproperty Name of Two Parent Properties of the Same Type

JustMock R3 2016 (2016.3.914.2)

The below test will pass when the second ArrangeSet should fail instead. I tried reporting the issue through VS2013 but I got a CommunicationException error: The server did not provide a meaningful reply.

[TestMethod]
public void Test()
{

    var pageMock = Mock.Create<IPage>()
    Mock.ArrangeSet(() => pageMock.WebControl1.Enabled = false).OccursNever();
    Mock.ArrangeSet(() => pageMock.WebControl2.Enabled = false).MustBeCalled();

    Mock.Assert(pageMock);
}

The problem with `Install_TelerikJustMock.bat` file

JustMock Q2 2016 SP1 (2016.2.713.2)

I have the JustMock license. I installed JustMock (the JustMock_2016_2_713_2_Dev.msi file). Also I downloaded and extracted the `JustMock_2016_2_713_2_Help3.zip` file. Now I launch the `Install_TelerikJustMock.bat` file but I get the error message:

> Error: It isn't possible to find the specified section or parameter in the register.
> Ensuring same version not registered...
> ""\HelpLibManager.exe"" isn't internal or external
> command, runtime program or batch file.
> Registering the new version...
> ""\HelpLibManager.exe"" isn't internal or external
> command, runtime program or batch file.
> Done.
> Press any key for exit...

How can I solve it?
