I am trying to create a unit test similar to how I would have done one in C# but am struggling with the lambdas in vb. Bascially I am trying to mock a class and then create a stub and return. In C# I would have done something like;
MockedPersonRepository
.Stub(x => x.Find(id))
.Return(person)
[code].....
The following C# code works just fine and the test passes as expected.
using NUnit.Framework;
using Rhino.Mocks;
namespace RhinoMocksTesting
{
public interface ITesting
[Code]...
The Expect.Call line produces the following build error: "Overload resolution failed because no accessible 'Expect' accepts this number of arguments." What is the proper way to use Expect.Call with a mocked property in VB.NET? I've seen a couple posts that say Rhino Mocks works better in VB10, but I'm stuck with Visual Studio 2008 for this current project.
I have a read-only dictionary on a dependency that I'd like to be able to stub with return values, and check that assignments to it have happened.
I was hoping that Rhino.Mocks would create an empty dictionary for me by default, but unfortunately it doesn't. Since it is read-only, I can't create a new dictionary and assign it to that property.
I was hoping to be able to stub it instead. From what I understand, the C# syntax for this would looking something like this:
m.Stub(x => x.myProperty).Return("abc");
So I was hoping that this would work for VB:
m.Stub(sub(x) x.myProperty).Return("abc");
But it doesn't (compiler error). how to accomplish this? I'm open to the Expect/Verify syntax if it can accomplish this...
I remember that to set expectations on methods that return void in C# one has to write: mockedRepository.Expect(() => mr.AddUser(someUser)).DoOtherStuff()where AddUser returns void.How to achieve the same in VB.NET?
EDIT:I've found similar question. May be helpful: How to mock a method with Rhino Mocks in VB.NET .
Probably a dumb question, but can you write a unit test project in one language to test against another project in a different language?I'd like to translate one of our VB assemblies into C#, but want to build unit tests to verify the results. I've tried to set a unit test project up to do this, but I can't seem to access the VB code within a unit test... I can't figure out if I'm just missing/doing something stupid, or it really isn't allowed.

I created some string resources in My.Resources. I want to use those resources in my unit tests.How do I expose these resources to my unit test project?I tried simply setting the Access Modifier to "Public" for the resources.

I am writing a test unit (in MSTest) that consumes an XML file located in the testing project. I have this (solution name is BusinessLogic, project name is BusinessLogicTest):
Public TestContext As TestContext

<DataSource("Microsoft.VisualStudio.TestTools.DataSource.XML",
"|DataDirectory|TestData.xml", "Row", DataAccessMethod.Sequential)> _
Public Sub ConvertIntToRoman_DataDrivenTest
[Code] .....
However, when I run the test I get an error: The unit test adapter failed to connect to the data source or to read the data. I belive it's something to do with my DeploymentItem and/or DataSource, however, I cannot find an example (in VB) that works anywhere.
Is there currently any possible way to report progress of my unit test? I have a test that could take up to a hour, and I don't want to sit there not knowing what % it is done with. I have tried writing with debug.print and trace.writeline, neither of which seem to work.
View 1 RepliesI am having a problem with a unit test I have created. First time doing this so I am not sure why I am getting this error [code]Test method ETDS_Unit_Tests.LoginTest.ValidateUserNameTest threw exception: System.Data.SqlClient.SqlException: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.

View 2 RepliesI have a constructor that looks like this:
Public Sub New()
MyBase.New()
ws.Url = My.Settings.WebServiceURL
End Sub
(ws is private)
Is there any point in unit testing this?
The class did not previously have this constructor.
Usually when you add one (in Visual Basic), it pops up a message asking if you want to enable an option that lets the test access things like private methods etc.
However, I am editing a solution that does not have this enabled. I'd like to enable it so my unit tests will work, but I can't find the setting.
Can anyone tell me how to enable it after the project has been created?
I have the following code in vb.net that calculates the amount before tax was applied:

View 5 RepliesI am writing a winforms application and eventually I would like to write unit test for this application from the DAL, and Biz Objects layers etc.
Does someone know of a FREE tool that can recieve the path to an assembly and then output unit test stubs with matching signatures for the assembly.
Any configurable options like "public interfaces only", "test framework choice", "language choice" would be a plus.
One of my unit tests seems to randomly pass or fail when I run it. The only thing that makes sense to me for why this is happening is if the data in the database is getting into a different state each time the test is ran, but I use transactions to rollback the database in each test - unless it's not working right. Here's my base unit test class and the unit test class that's having the problem. Can you see anything I might be missing or what else I should look for?
This happens with TestDriven.Net and the Visual Studio Unit Test Framework.

As I develop code, I often want to unit test some of the building blocks of a class even if they are normally private. If my unit tests are inside the project, I can use "Friend" to accomplish this and still keep the functions private for normal use. But I would rather move my NUnit tests into their own separate project(s). How do I achieve the effe vb.net 2005?

View 8 RepliesI've set up a test database to begin unit-testing an app that I've recently been added to. It is a 3-tier design (presentation layer, BOL and DAL) and this is my first time writing unit tests. I've decided to start at the BOL and I figure the best way is to swap out the ConnectionString (which has been passed along as a Shared String) with one that points to my new test database. However, I don't wish to change any production code. I simply wish to somehow redirect the app to the test database during unit tests.
View 4 RepliesI have a solution with two projects within:
Company.Project.vbproj
Company.Project.Tests.vbproj
Within the Company.Project.vbproj assembly, I have a class FriendClass.vb which scope is Friend (internal in C#).Now I wish to test this FriendClass.vb from within the Company.Project.Tests.vbproj assembly. I know about the InternalsVisibleToAttribute, but that is not an option in Visual Basic .NET 2.0, as it is only available with C#, in .NET 2.0 (see here).I would like to create myself a proxy class using this internal FriendClass from within my testing assembly, so that I could instantiate it and do the testings accordingly.
We have a WCF service hosted in IIS that currently calls a VB6 DLL to do part of its job. This works fine, but we can't deploy the service to a 64-bit target environment without configuring IIS to run it in a 32-bit worker process.I am currently investigating ways around that restriction. Porting the VB6 DLL to .NET is not possible for various reasons, so I created an ActiveX EXE wrapper around the DLL in VB6, so that the service can run in 64-bit and the VB6 parts in 32-bit.
When I tested the service I got this error:
Type: System.UnauthorizedAccessException
Message: Retrieving the COM class factory for component with CLSID {9AE7303B-D159-43F6-B1A5-52D297581820} failed due to the following error: 80070005.
After some Googling I found that this is due to either:
Calling an MS Office component
DCOM permissions not being configured
NTFS file permissions not allowing read/exec access to the IIS worker process identity (ASPNET in my environment)
Of these:
Definitely not applicable Also not applicable; I am not hosting the EXE in DCOM or COM+, just a simple COM out-of-process activation
This looks likely; however, I checked the permissions, and NTFS reports that the Users group (which ASPNET is a member of) does indeed have read/exec access to the file I tried calling the EXE from a unit test fixture, which is executed in my admin-level account rather than the IIS worker process account, and it worked fine, so the error is definitely something to do with permissions. I'm not sure what to do next.
UPDATE:The IIS virtual directory is configured for Anonymous+Windows access; the WCF service uses only Anonymous authentication, the Windows authentication is for the VS debugger. Task Manager reports that the aspnet_wp.exe process is definitely running in the ASPNET account.I explicitly granted Read and Execute access to the ASPNET and IUSR_<machine> accounts on all the COM exes and dlls involved. This made no difference.
I explicitly granted Local Launch and Local Activation access to the ASPNET and IUSR_<machine> accounts on the relevant interfaces in the DCOM configuration. This made no difference either.Keep trying to get this working somehow.Go the whole hog and host the EXE in COM+.Give up. Tell users that the WCF service must be configured to run in a 32-bit app pool on 64-bit Windows.
I have written one application which communicate with one data logger unit (temperature monitoring unit) and download records after some interval. Unit continuously send current temperature which I have to show on screen and after each one hour I have to download log (all records saved inside unit at max 1024) from unit.
Now problem is after downloading log, application get hang or what we called working in background and resume after some time. If I pause debugger in visual studio 2008 it show control at application start (sub main) with message as "application will resume here after completing execution of current function". There is nothing in output window. So how can i trace is there any events got spool or what actually application doing in background.
