• Microsoft BizTalk Server vNext (after 2009 R2) - Feature Request

  - by Saravana Kumar

  All, This post is not a question; it’s more of asking for feed back and future request. The product team is always looking for feed back to facilitate the future direction of the product. Some of us as BizTalk Server MVP’s/partners get that privilege to work with the product team closely to give our feedback regularly based on our real world experience. But I believe there is a much wider BizTalk community out there working on closed door project that tests the strength of the product to extreme levels. I would like those passionate people to come forward and put their feature request. Let’s use the power of StackOverflow to help us here. We can vote up and down on each feature request, and see what's going to top the chart. I hope this will be a useful exercise. Updated 24th Feb: If you got more than one request, please post it as separate answers. So, its easy to vote against them.

• Situations to prefer Apache Lucene over Solr?

  - by Karussell

  There are several advantages to use Solr (out-of-the-box facetting search, grouping, replication, http administration vs. luke, ...). Even if I embed a search-functionality in my Java application I could use SolrJ to avoid the HTTP trade-off when using Solr. So, when would you recommend to use "pure-Lucene"? Does it have a better performance or requires less RAM? Is it better unit-testable? PS: I am aware of this question.

• Eclipse (Springsource Tool Suite 2.3.1) can't resolve dependencies for classes in the same package

  - by Steve

  This started happening when I upgraded my Springsource Toolsuite from 2.3 to 2.3.1. Essentially whenever I do anything, such as open a file, change a file, etc, I have to do a clean. Everything works fine when I do mvn commands on the command line, which leads me to believe that Eclipse is looking in the wrong place for compiled code or something along those lines, although that is entirely superstitious at this point. Example: I make a change to com.foo.mypackage.MyClass. Suddenly a bunch of tests that excercise MyClass get the red x - for class not found! In src/main/test: com.foo.DbUnitTest com.foo.mypackage.FooTest extends DbUnitTest DbUnitTest gets a class not found. I do a clean, and everything is fine. I touch something, and it breaks again :(. I don't really know where to begin on how to troubleshoot this.

• Polling duplex does not scale... what's the alternative?

  - by user80855

  Our tests showed that the polling duplex binding simply does not scale and can not be used on a service within a web-farm or even a web garden. We have looked at TCP/IP sockets for a client push method, but the firewall issue is does allow us to use sockets. I was wondering what is the alternative "free" solution to this problem? allowing us to scale and allowing us to push data to client... I have also tried the solution in this article http://tomasz.janczuk.org/2009/09/scale-out-of-silverlight-http-polling.html but at the end, there was too much polling on a database, and performance was affected. Our Silverlight application need a pub/sub design, but it needs to be reliable and scalable... any ideas?

• Handling changes in an interface shared across multiple solutions?

  - by Anthony Mastrean

  Our "main" solution is the development code: shared libraries, services, UI projects, etc. The other solution is an integration and automated tests solution. It references several of the development projects. The reason it is separate is to avoid interference with the development solution's unit test VSMDI file. And to allow us to play with different execution methods (other test runners, like Gallio or StoryTeller) without interfering with the development solution. Recently, an interface changed in the development solution, one of our test mocks implemented that interface. But, it was not updated because there was no warning at compile time because it was in another solution. This broke our CI build. Does anyone have a similar setup? How do you handle these issues, do you follow a strict procedure or is there some kind of technical answer?

• oAuth provider with Django-piston

  - by Martin Eve

  Hi, I'm working with django-piston to attempt to create an API that supports oAuth. I started out using the tutorial at: http://blog.carduner.net/2010/01/26/django-piston-and-oauth/ I added a consumer to piston's admin interface with key and secret both set to "abcd" for test purposes. The urls are successfully wired-up and the oAuth provider is called. However, running my get request token tests with tripit (python get_request_token.py "http://127.0.0.1:8000/api" abcd abcd), I receive the following error: Invalid signature. Expected signature base string: GET&http%3A%2F%2F127.0.0.1%3A8000%2Fapi%2Foauth%2Frequest_token%2F&oauth_consumer_key%3Dabcd%26oauth_nonce%3D0c0bdded5b1afb8eddf94f7ccc672658%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1275135410%26oauth_version%3D1.0 The problem seems to lie inside the _check_signature method of Piston's oauth.py, where valid_sig = signature_method.check_signature(oauth_request, consumer, token, signature) is returning false. I can't, however, work out how to get the signature validated. Any ideas?

• CSharpCodeProvider: Why is a result of compilation out of context when debugging

  - by epitka

  I have following code snippet that i use to compile class at the run time. //now compile the runner var codeProvider = new CSharpCodeProvider( new Dictionary<string, string>() { { "CompilerVersion", "v3.5" } }); string[] references = new string[] { "System.dll", "System.Core.dll", "System.Core.dll" }; CompilerParameters parameters = new CompilerParameters(); parameters.ReferencedAssemblies.AddRange(references); parameters.OutputAssembly = "CGRunner"; parameters.GenerateInMemory = true; parameters.TreatWarningsAsErrors = true; CompilerResults result = codeProvider.CompileAssemblyFromSource(parameters, template); Whenever I step through the code to debug the unit test, and I try to see what is the value of "result" I get an error that name "result" does not exist in current context. Why?

• Selection of parameters in Diffie-Hellman

  - by allenzzzxd

  Hello, maybe it's not so proper to ask this question here... anyway, I'm trying to use the gmp library for the implementation of DH, but the problem here I got is: Once, when I was doing the tests to observe the output, although big values of prime and the private keys were selected: p was about more than 300 digits long in decimal a, b were about 100 digits long finally I got a shared secret key which was extremely small, perhaps smaller than 10^8 in decimal... This problem didn't show up many times, in fact, during all the observation, it appeared just once...but still, this was not so good at all. So I wonder if there are some methods which can avoid this... Thanx a lot

• PPP connection with RAS dialer in C++

  - by user312054

  I have a windows mobile application that is using Windows CE 5.0. I have been informed by the people supplying the hardware for the unit that I need to create a socket, which I have done successfully, and then dial out to the internet with a PPP connection with a RAS dialer connection. Our old code uses an APN to dial out so I need to create the above connection with an APN. I am having trouble finding examples of this. Can someone point me to some examples of this situation?

• Starting a VC++ .exe from MSAccess

  - by Pieter_Jack

  For a complex calculating problem we use an VC++ module (.exe). For the users we have build an ms Access application as userinterface. After input dthe calculating module should start and do its job. The result is again imported in Ms Access. However we work wit dBase files (.dbf) as datafiles. The calculating unit works fine by its own, but when access is running it wo'nt do its job. It will start-up when called from the Access module, but then generates errors or at least does not write correct results to a datatable. We cannot find the reason for this beheavior. Can anyone give us a tip?

• Linq to sql add/update in different methods with different datacontexts

  - by Kurresmack

  I have to methods, Add() and Update() which both create a datacontext and returns the object created/updated. In my unit test I call first Add(), do some stuff and then call Update(). The problem is that Update() fails with the exception: System.Data.Linq.DuplicateKeyException: Cannot add an entity with a key that is already in use.. I understand the issue but want to know what to do about it? I've read a bit about how to handle multiple datacontext objects and from what I've heard this way is OK. I understand that the entity is still attached to the datacontext in Add() but I need to find out how to solve this? Thanks in advance

• How to get a handle/reference to the current controller object inside a rails functional test?

  - by Dave Paroulek

  I must be missing something very simple, but can't find the answer to this. I have a method named foo inside bar_controller. I simply want to call that method from inside a functional test. Here's my controller: class BarsController < ApplicationController def foo # does stuff end end Here's my functional test: class BarsControllerTest << ActionController::TestCase def "test foo" do # run foo foo # assert stuff end end When I run the test I get: NameError: undefined local variable or method `foo' for #<BarsControllerTest:0x102f2eab0> All the documentation on functional tests describe how to simulate a http get request to the bar_controller which then runs the method. But I'd just like to run the method without hitting it with an http get or post request. Is that possible? There must be a reference to the controller object inside the functional test, but I'm still learning ruby and rails so need some help.

• Get the full URI from the href property of a link

  - by Savageman

  Hello SO, I would like to have a confirmation on some point. My goal is to always get the same string (which is the URI in my case) while reading the href property from a link. Example: <a href="test.htm" /> with base_url = http://domain.name/ <a href="../test.htm" /> with base_url = http://domain.name/domain/ <a href="http://domain.name/test.htm" /> with base_url = any folder from http://domain.name/ I need to get http://domain.name/test.htm from the 3 situations above (or any other identical string). After some tests, it appears that my_a_dom_node.href always return the full-qualified URI, including the http://domaine.name, which should be okay for what I want. jQuery has a different behaviour and $(my_a_dom_node).attr('href') returns the content (text) that appears inside the HTML. So my trick is to use $(my_a_dom_node).get(0).href to get the full URI. The question is: can I rely on this?

• Anyone have an XSL to convert Boost.Test XML logs to a presentable format?

  - by Stuart Lange

  I have some C++ projects running through cruisecontrol.net. As a part of the build process, we compile and run Boost.Test unit test suites. I have these configured to dump XML log files. While the format is similar to JUnit/NUnit, it's not quite the same (and lacks some information), so cruisecontrol.net is unable to pick them up. I am wondering if anyone has created (or knows of) an existing XSL transform that will convert Boost.Test results to JUnit/NUnit format, or alternatively, directly to a presentable (html) format. Thanks!

• Cucumber/Webrat: follow link by CSS class?

  - by Joe

  Hello there, is it possible to follow a link by it's class name instead of the id, text or title? Given I have (haha, cucumber insider he?) the following html code: <div id="some_information_container"> <a href="edit" class="edit_button">Translation here</a> </div> I do not want to match by text because I'd have to care about the translation values in my tests I want to have my buttons look all the same style, so I will use the CSS class. I don't want to assign a id to every single link, because some of them are perfectly identified through the container and the link class Is there anything I missed in Cucumber/Webrat? Or do you have some advices to solve this in a better way? Thanks for your help and best regards, Joe edit: I found an interesting discussion going on about this topic right here - seems to remain an open issue for now. Do you have any other solutions for this?

• How should moq's VerifySet be called in VB.net

  - by Bender

  I am trying to test that a property has been set but when I write this as a unit test: moqFeed.VerifySet(Function(m) m.RowAdded = "Row Added") moq complains that "Expression is not a property setter invocation" My complete code is Imports Gallio.Framework Imports MbUnit.Framework Imports Moq <TestFixture()> Public Class GUI_FeedPresenter_Test Private moqFeed As Moq.Mock(Of IFeedView) <SetUp()> Sub Setup() moqFeed = New Mock(Of IFeedView) End Sub <Test()> Public Sub New_Presenter() Dim pres = New FeedPresenter(moqFeed.Object) moqFeed.VerifySet(Function(m) m.RowAdded = "Row Added") End Sub End Class Public Interface IFeedView Property RowAdded() As String End Interface Public Class FeedPresenter Private _FeedView As IFeedView Public Sub New(ByVal feedView As IFeedView) _FeedView = feedView _FeedView.RowAdded = "Row Added" End Sub End Class I can't find any examples of moq in VB, I would be grateful for any examples.

• ActiveX controls with old Delphi versions

  - by DamienD

  I'm testing a non visual ActiveX control based on a registered .ocx which I import into Delphi using the provided wizard. Then, I simply put the generated component on the main form of a new VCL application. Under old Delphi versions (D5 and D2007), when i launch the application, this raise an AV during the component initialization. with Delphi 2009 : no problem, the application starts smoothly. My questions are : Are there known enhancements of ActiveX management in recent Delphi versions which can explain this difference ? Can I suspect a bug in the ActiveX control, or can I consider the origin of the problem is from old Delphi versions ? I need to use this component (if tests OK) in D2007. Do you think that it is possible to correct the AV problem under D2007 by modifying the D2007 generated .tlb file (for example by trying to use the D2009 generated one) PS: the ActiveX control is not named, because my question is a general question about Delphi and ActiveX, not about a specific ActiveX control.

• Excluding standard directories from code coverage results with C++/CLI

  - by brickner

  I have a Visual Studio 2010 .NET 4 solution with C# projects and a C++/CLI project. I use Visual Studio's built in unit tests and code coverage. Other than the fact that Visual Studio 2010 coverage tool for C++/CLI projects seems to be much weaker than Visual Studio 2008 coverage tool, I get weird results. For example, I get uncovered code in this file: c:\program files (x86)\microsoft visual studio 10.0\vc\include\xstring And some other files in that directory. I want to exclude this code from coverage results. Is there a way to put some exclude attributes on that code? If not, is there a different automatic way to exclude that code from coverage? If not, is there a way to use EXCLUDE option to exclude it? Can it be done automatically within Visual Studio without running the coverage tool from command prompt? Any other solutions?

• how to prevent white spaces in a regular expression regex validation

  - by Rees

  i am completely new to regular expressions and am trying to create a regular expression in flex for a validation. using a regular expression, i am going to validate that the user input does NOT contain any white-space and consists of only characters and digits... starting with digit. so far i have: expression="[A-Za-z][A-Za-z0-9]*" this correctly checks for user input to start with a character followed by a possible digit, but this does not check if there is white space...(in my tests if user input has a space this input will pass through validation - this is not desired) can someone tell me how i can modify this expression to ensure that user input with whitespace is flagged as invalid?

• Using TSQLUnit to test INSTEAD OF triggers

  - by Jeff Jones

  I have an INSTEAD OF trigger on a table in my SQL Server 2005 database that checks several incoming values. If an incoming value is invalid, an error is raised and the transaction is rolled back. Otherwise the record is inserted. I would like to include a TSQLUnit test of this trigger where, if an invalid value is inserted, having the transaction rolled back is the successful outcome of the test. I have created a test procedure to do this, but rolling back the transaction aborts execution of the whole suite of tests. Has anyone had success with this? If so, how did you accomplish it? If this is not possible with TSQLUnit, how do you test your triggers? Or do you test them at all?

• Setting up gcov in Xcode 3.1

  - by Algorithmic

  I'm trying to setup my Xcode project to be instrumented with gcov so I can determine the code coverage of my unit tests. All of the documentation I find online talks about settings that I don't find in Xcode 3.1, though. An example: To work with Coverstory, first you need to set up your target to work with gcov. This requires turning on "Instrument Program Flow", "Generate Test Coverage Files" and linking with the gcov library. (Using Coverstory) The closest thing I can find to "Instrument Program Flow" and "Generate Test Coverage Files" in my build settings is "Generate Profiling Code", which doesn't appear to do what I want it to do. Am I looking in the wrong place for these settings or are all of the examples I'm finding online stale?

• Viewing Code Coverage Results outside of Visual studio

  - by Wonchance

  I've got some unit tests, and got some code coverage data. Now, I'd like to be able to view that code coverage data outside of visual studio, say in a web browser. But, when I export the code coverage to an xml file, I can't do anything with it. Are there readers out there for this? Do I have to write an xml parser and then display it how I want it (seems like a waste since visual studio already does this.) Seems kinda silly to have to take a screenshot of my code coverage results as my "report" Suggestions?

• How to prepare for a Java test?

  - by Zenzen

  Ok so in two days I have a test for my dream job (well it's an internship, but still!) and for quite some time now I've been reading the SCJP Guide book in order to prepare myself. BUT seeing how slow my reading speed is I guess finding a website with some "java essentials" or "standard java test questions" and going through it in those 2 days would be a better idea. Don't misunderstand me, I do have java experience and it's "only" an internship, but we all know how programming tests look like and how tricky they can be. So are there any online resources you could recommend me? I know 2 days is not much, but well I was informed bout the test 1-2days ago.

• Does it make sense to commit after every save with a DVCS?

  - by blockhead

  I know the question has been asked before how often to commit with a DVCS. All answers have one thing in common--as often as possible. But they're usually something like, after finishing a thought, a user story, getting code that compiles, or passing tests. I was thinking, given that a DVCS gives you you're own repository, with very cheap commits, doesn't it make sense, to commit after every change to a file? After all, this is what happens in NetBeans, and you get a nice free "time machine" without even asking for it. If not every change, then at least every save, or compile. Does this make sense, or do I have the wrong idea about DVCS. My feeling is that this not the workflow most people have with DVCS.

• BigDecimal precision not persisted with javax.persistence annotations

  - by dkaczynski

  I am using the javax.persistence API and Hibernate to create annotations and persist entities and their attributes in an Oracle 11g Express database. I have the following attribute in an entity: @Column(precision = 12, scale = 9) private BigDecimal weightedScore; The goal is to persist a decimal value with a maximum of 12 digits and a maximum of 9 of those digits to the right of the decimal place. After calculating the weightedScore, the result is 0.1234, but once I commit the entity with the Oracle database, the value displays as 0.12. I can see this by either by using an EntityManager object to query the entry or by viewing it directly in the Oracle Application Express (Apex) interface in a web browser. How should I annotate my BigDecimal attribute so that the precision is persisted correctly? Note: We use an in-memory HSQL database to run our unit tests, and it does not experience the issue with the lack of precision, with or without the @Column annotation.
