  • Visual Studio Unit Test failure to start

    - by swmi
    Hi, I am having an issue when starting the tests under debug mode in Visual Studio 2008 Team Test where it gives the following error: "Failed to queue test run '{user@machinename}': Object reference not set to an instance of an object." I googled for the error but no joy. Don't even understand what it means as it is too brief. Has anyone come across this? Note that I can run tests fine if I am not debugging and I get the same error irrespective of the test I run. Thank you, Swati ETA: Being new to Visual Studio Team Test, I didn't know there was a better exception log then what I was seeing. Anyhow, here it is: <Exception> System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.VisualStudio.TestTools.TestCaseManagement.QualityToolsPackage. ShowToolWindow [T](T&amp; toolWindow, String errorMessage, Boolean show) at Microsoft.VisualStudio.TestTools.TestCaseManagement.QualityToolsPackage.

  • custom attribute changes in .NET 4

    - by Sarah Vessels
    I recently upgraded a C# project from .NET 3.5 to .NET 4. I have a method that extracts all MSTest test methods from a given list of MethodBase instances. Its body looks like this: return null == methods || methods.Count() == 0 ? null : from method in methods let testAttribute = Attribute.GetCustomAttribute(method, typeof(TestMethodAttribute)) where null != testAttribute select method; This worked in .NET 3.5, but since upgrading my projects to .NET 4, this code always returns an empty list, even when given a list of methods containing a method that is marked with [TestMethod]. Did something change with custom attributes in .NET 4? Debugging, I found that the results of GetCustomAttributesData() on the test method gives a list of two CustomAttributeData which are described in Visual Studio 2010's 'Locals' window as: Microsoft.VisualStudio.TestTools.UnitTesting.DeploymentItemAttribute("myDLL.dll") Microsoft.VisualStudio.TestTools.UnitTesting.TestMethodAttribute() -- this is what I'm looking for When I call GetType() on that second CustomAttributeData instance, however, I get {Name = "CustomAttributeData" FullName = "System.Reflection.CustomAttributeData"} System.Type {System.RuntimeType}. How can I get TestMethodAttribute out of the CustomAttributeData, so that I can extract test methods from a list of MethodBases?

  • How do I test how my client program will react to a web server error?

    - by Brad Bruce
    I have a client program based on LibCurl. I have run into a situation where on some occasions a program on the server runs longer than the configured IIS timeout. IIS then terminates the program and returns a 502 error status to the client. I have added code to the client to capture this issue. Now, I need to find a way to prove that the change will work. I haven't been able to reliably reproduce the issue, so don't have a good test case. Any suggestions?

  • How can I write a unit test to determine whether an object can be garbage collected?

    - by driis
    In relation to my previous question, I need to check whether a component that will be instantiated by Castle Windsor, can be garbage collected after my code has finished using it. I have tried the suggestion in the answers from the previous question, but it does not seem to work as expected, at least for my code. So I would like to write a unit test that tests whether a specific object instance can be garbage collected after some of my code has run. Is that possible to do in a reliable way ? EDIT I currently have the following test based on Paul Stovell's answer, which succeeds: [TestMethod] public void ReleaseTest() { WindsorContainer container = new WindsorContainer(); container.Kernel.ReleasePolicy = new NoTrackingReleasePolicy(); container.AddComponentWithLifestyle<ReleaseTester>(LifestyleType.Transient); Assert.AreEqual(0, ReleaseTester.refCount); var weakRef = new WeakReference(container.Resolve<ReleaseTester>()); Assert.AreEqual(1, ReleaseTester.refCount); GC.Collect(); GC.WaitForPendingFinalizers(); Assert.AreEqual(0, ReleaseTester.refCount, "Component not released"); } private class ReleaseTester { public static int refCount = 0; public ReleaseTester() { refCount++; } ~ReleaseTester() { refCount--; } } Am I right assuming that, based on the test above, I can conclude that Windsor will not leak memory when using the NoTrackingReleasePolicy ?

  • Jquery ajax load of JSON in unit tests

    - by wmitchell
    I'm trying to load a dataset in jasmine for my tests like such ... However as its a json call I cant seem to always get the test denoted by "it" to wait till the JSON call has finished before using its array. I tried using the ajaxStop function to no avail. Any ideas ? describe("simple checks", function() { var exampleArray = new Array(); beforeEach(function(){ $(document).ajaxStop(function() { $(this).unbind("ajaxStop"); $.getJSON('/jasmine/obj.json', function(data) { $.each( json.jsonattr, function(i, widgetElement) { exampleArray.push(new widget(widgetElement)); }); }); }); }); it("use the exampleArray", function() { doSomething(exampleArray[0]); // frequently this is coming up as undefined });

  • Why are my rails tests so slow?

    - by ryeguy
    Is it normal for my test suite to take 5 seconds just to launch? Even when running an empty suite it still takes this long. Is it because it's firing up a new instance of rails on each run? If so, is there anyway to keep it persistent? I'm using Test::Unit with Shoulda.

  • In an Android test, how to check that a View is shown?

    - by Jan Zankowski
    Hello, I'm writing a UI test case (using ActivityUnitTestCase) and would like to check if at a given time a View subclass is visible to the user. I've found the View#isShown() method, which claims to do exactly this - checking the visibility field of this element and all its parents - but somehow it always returns "false" for all the elements. I'll be grateful for some help. If it makes it easier, I can paste some code. Also, I found ViewAsserts#assertOnScreen(View origin, View view) but it doesn't seem to do the right thing either - always returns true. Am I perhaps calling it wrong: assertOnScreen(viewImTesting.getRootView(), viewImTesting)? Thanks, Jan

  • How to specify a web service URL within a Drupal module's simpletest?

    - by Matt V.
    I have a Drupal module that talks to a REST API on a separate server for user registration and authentication. The module runs on multiple sites which point to different servers which may run different versions of the REST API. Ideally, I'd like to be able to run each site against its own end-point, in case changes on the back end break things. Is there a way to dynamically specify a different end-point URL when running a test? Or do I have to edit the .test file for each site? I'm trying to keep the module's files as generic and flexible as possible. I guess I could have the .test file look for a .inc file that could override the URL, if needed for a particular site. Is there a better way though?

  • How to test method call order with Moq

    - by Finglas
    At the moment I have: [Test] public void DrawDrawsAllScreensInTheReverseOrderOfTheStack() { // Arrange. var screenMockOne = new Mock<IScreen>(); var screenMockTwo = new Mock<IScreen>(); var screens = new List<IScreen>(); screens.Add(screenMockOne.Object); screens.Add(screenMockTwo.Object); var stackOfScreensMock = new Mock<IScreenStack>(); stackOfScreensMock.Setup(s => s.ToArray()).Returns(screens.ToArray()); var screenManager = new ScreenManager(stackOfScreensMock.Object); // Act. screenManager.Draw(new Mock<GameTime>().Object); // Assert. screenMockOne.Verify(smo => smo.Draw(It.IsAny<GameTime>()), Times.Once(), "Draw was not called on screen mock one"); screenMockTwo.Verify(smo => smo.Draw(It.IsAny<GameTime>()), Times.Once(), "Draw was not called on screen mock two"); } But the order in which I draw my objects in the production code does not matter. I could do one first, or two it doesn't matter. However it should matter as the draw order is important. How do you (using Moq) ensure methods are called in a certain order? Edit I got rid of that test. The draw method has been removed from my unit tests. I'll just have to manually test it works. The reversing of the order though was taken into a seperate test class where it was tested so it's not all bad. Thanks for the link about the feature they are looking into. I sure hope it gets added soon, very handy.

  • Visual Studios Team System 2008 Code Coverage Window Closes

    - by ThoughtCrhyme
    Trying to run the code coverage tool in Visual Studios for a set of unit tests. Adam from Think First, Code Later has had the same problem: I wanted to get the code coverage metrics for the project. Naturally, I fire up the solution in Visual Studio 2008, go to the Test menu, click Edit Test Run Configurations, and click Local Test Run. I then click Code Coverage to turn on code coverage for a given assembly and POOF the Local Test Run Configraution window just disappears. He recommends installing this hotfix to fix the problem, however a) when I run that hotfix I get the message “None of the products that are addressed by this software update are installed on this computer. Click Cancel to exit setup.” and b) there is no Silverlight in our solution. Any other ideas for a fix?

  • NHibernate How to specify custom sql type only in production

    - by Davide Orazio Montersino
    I am saving binary files into a Sql Server 2005 Db using Fluent NHibernate. However, I am using SQLite to run my (pseudo) Unit Tests. I need to use a custom Sql type for Ms Sql, but it would throw an error on SqlLite. What strategies can I use? This is the Map file: public class BinaryFile { public BinaryFile() { m.Map(x => x.BinaryData);//.CustomSqlType("varbinary(MAX)"); m.Map(x => x.ContentType); m.Map(x => x.FileName); m.Map(x => x.FileSize); } }

  • Is there a efficient way to do multiple test cases in c?

    - by Ahmed Abdelaal
    I use MS Visual Studio and I am new to C++, so I am just wondering if there is an faster more efficient way to do multiple test cases instead of keep clicking CTRL+F5 and re-opening the console many times. Like for example if I have this code #include <iostream> using namespace std; void main () { int x; cout<<"Enter a number"<<endl; cin>>x; cout<<x*2<<endl; } Is there a way I could try different values of x at once and getting the results together? Thanks

  • How do you test a command object in a grails controller integration test?

    - by egervari
    I'm new to grails. How do I test a form command object to make sure that it's working? Here's some setup code in a test. When I try to do it, I get the following exceptions: Error occurred creating command object. org.codehaus.groovy.grails.web.servlet.mvc.exceptions.ControllerExecutionException: Error occurred creating command object. at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) .... Caused by: groovy.lang.MissingPropertyException: No such property: password for class: project.user.RegistrationForm Possible solutions: password Here is my test case. As you can see, I set "password" on the params map... void testSaveWhenDataIsCorrect() { controller.params.emailAddress = "[email protected]" controller.params.password = "secret" controller.params.confirmPassword = "secret" controller.save() assertEquals "success", redirectArgs.view ... } Here's the controller action, that adds the command object as a closure parameter: def save = { RegistrationForm form -> if(form.hasErrors()) { render view: "create", model: [form: form] } else { def user = new User(form.properties) user.password = form.encryptedPassword if(user.save()) { redirect(action: "success") } else { render view: "create", model: [form: form] } } } Here's the command object itself... and note that it DOES have a "password" field... class RegistrationForm { def springSecurityService String emailAddress String password String confirmPassword String getEncryptedPassword() { springSecurityService.encodePassword(password) } static constraints = { emailAddress(blank: false, email: true) password(blank: false, size:4..10) confirmPassword(blank: false, validator: { password != confirmPassword }) } } I'm totally lost in the non-intuitive way to do controllers... Please help.

  • How to: generate UnhandledException?

    - by serhio
    I use this code to catch the WinForm application UnhandledException. [STAThread] static void Main(string[] args) { // Add the event handler for handling UI thread exceptions to the event. Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_ThreadException); // Set the unhandled exception mode to force all Windows Forms errors // to go through our handler. Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException); // Add the event handler for handling non-UI thread exceptions to the event. AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException); try { Application.Run(new MainForm()); } catch.... There I will try to restart the application. Now my problem is to simulate a exception like this. I tried before try (in main): throw new NullReferenceException("test"); VS caught it. Tried also in MainForm code with button : private void button1_Click(object sender, EventArgs ev) { ThreadPool.QueueUserWorkItem(new WaitCallback(TestMe), null); } protected void TestMe(object state) { string s = state.ToString(); } did not help, VS caught it, even in Release mode. How should I, finally, force the application generate UnhandleldException? Will I be able to restart the application in CurrentDomain_UnhandledException?

  • [Zend] phpUnit - assertQuery fails with

    I am having trouble with an assertQuery(). In the html I have (verified by outputting the body) <input type="text" name="LASTNAME" id="LASTNAME" value="" maxlength="25" size="20" /> So I wrote a query for it to test to make sure this element exists and that the value is empty $this->assertQuery('input#LASTNAME[value=""]', 1); PhpUnit says the assertion fails Failed asserting node DENOTED BY input#LASTNAME[value=""] EXISTS Can you give me some insight into why this assertion fails and how to write it properly? Thanks in advance!

  • Test MVC using moq

    - by Raminder
    I am new to moq and I was trying to test a controller (MVC) behaviour that when the view raises a certain event, controller calls a certain function on model, here are the classes - public class Model { public void CalculateAverage() { ... } ... } public class View { public event EventHandler CalculateAverage; private void RaiseCalculateAverage() { if (CalculateAverage != null) { CalculateAverage(this, EventArgs.Empty); } } ... } public class Controller { private Model model; private View view; public Controller(Model model, View view) { this.model = model this.view = view; view.CalculaeAverage += view_CalculateAverage; } priavate void view_CalculateAverage(object sender, EventArgs args) { model.CalculateAverage(); } } and the test - [Test] public void ModelCalculateAverageCalled() { Mock<Model> modelMock = new Mock<Model>(); Mock<View> viewMock = new Mock<View>(); Controller controller = new Controller(modelMock.Object, viewMock.Object); viewMock.Raise(x => x.CalculateAverage += null, new EventArgs.Empty); modelMock.Verify(x => x.CalculateAverage()); //never comes here, test fails in above line and exits Assert.True(true); } The issue is that the test is failing in the second last line with "Invocation was not performed on the mock: x = x.CalculateAverage()". Another thing I noticed is that the test terminates on this second last line and the last line is never executed. Am I doing everything correct?

  • Open Source: Is Testing/Bug Reporting A Major Contribution?

    - by dsimcha
    When evaluating contributions to open source projects, does testing the code on various real-world inputs, reducing a large number of complicated bugs to small test cases and filing good bug reports count as a significant contribution? I've done this for several open-source projects (specifically D compilers) where I wanted to help out but the codebase was too complicated to learn my way around in the amount of spare time I have. I'm interested in both the perspective of the main developers (those that write the code and fix the bugs) and from the perspective of employers (in case I want to put it on my resume at some point).

  • Moq.Mock<T> - how to setup a method that takes an expression

    I am Mocking my repository interface and am not sure how to setup a method that takes an expression and returns an object? I am using Moq and NUnit Interface: public interface IReadOnlyRepository : IDisposable { IQueryable<T> All<T>() where T : class; T Single<T>(Expression<Func<T, bool>> expression) where T : class; } Test with IQueryable already setup, but don't know how to setup the T Single: private Moq.Mock<IReadOnlyRepository> _mockRepos; private AdminController _controller; [SetUp] public void SetUp() { var allPages = new List<Page>(); for (var i = 0; i < 10; i++) { allPages.Add(new Page { Id = i, Title = "Page Title " + i, Slug = "Page-Title-" + i, Content = "Page " + i + " on page content." }); } _mockRepos = new Moq.Mock<IReadOnlyRepository>(); _mockRepos.Setup(x => x.All<Page>()).Returns(allPages.AsQueryable()); //Not sure what to do here??? _mockRepos.Setup(x => x.Single<Page>() //---- _controller = new AdminController(_mockRepos.Object); }

  • Google Web Optimizer -- How long until winning combination?

    - by Django Reinhardt
    I've had an A/B Test running in Google Web Optimizer for six weeks now, and there's still no end in sight. Google is still saying: "We have not gathered enough data yet to show any significant results. When we collect more data we should be able to show you a winning combination." Is there any way of telling how close Google is to making up its mind? (Does anyone know what algorithm does it use to decide if there's been any "high confidence winners"?) According to the Google help documentation: Sometimes we simply need more data to be able to reach a level of high confidence. A tested combination typically needs around 200 conversions for us to judge its performance with certainty. But all of our conversions have over 200 conversations at the moment: 230 / 4061 (Original) 223 / 3937 (Variation 1) 205 / 3984 (Variation 2) 205 / 4007 (Variation 3) How much longer is it going to have to run?? Thanks for any help.
