I have a protected static sub-class that I use for DataAccess. Its locked down so that no other part of the application/code can access or is aware of the database. I'm doing the unit tests for the host class and I need to Mock the protected static sub-class so that there are no database calls in the unit test. How do I do that and check occurances? Thanks.

public partial class Manager

{

protected static class DataAccess

{

public static void CallMyStoredProcedure()

{ }

}

displaymode is null when mocking ControllerContext

Hello,

I'm trying to mock a controller.ControllerContext and everything is working until the system tries to GetDisplayMode on the context. Since it is null, it blows up.

Here are two functions, the first creates the controller and the second uses the controller and blows up.

Any help would be appreciated!

Lee

private static LogonController CreateLogonController()

{

var controller = new LogonController();

var response = Mock.Create<HttpResponseBase>();

var httpContext = Mock.Create<HttpContextBase>();

var routeData = new RouteData();

var request = Mock.Create<HttpRequestBase>();

var cookies = new HttpCookieCollection();

var context = new ControllerContext(httpContext, routeData, Mock.Create<ControllerBase>());

var browser = Mock.Create<HttpBrowserCapabilitiesBase>();

response.Output = new StringWriter();

Mock.Arrange(() => browser.IsMobileDevice).Returns(false);

Mock.Arrange(() => request.Cookies).Returns(cookies);

Mock.Arrange(() => request.ValidateInput());

Mock.Arrange(() => request.UserAgent).Returns("Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.64 Safari/537.11");

Mock.Arrange(() => request.Browser).Returns(browser);

Mock.Arrange(() => response.Cookies).Returns(cookies);

Mock.Arrange(() => httpContext.Request).Returns(request);

Mock.Arrange(() => httpContext.Response).Returns(response);

routeData.Values.Add("controller", "LogonController");

routeData.Values.Add("action", "Index");

controller.ControllerContext = context;

return controller;

}

And here I am trying to use it to generate the output of a view:

public static class ApiExtensionMethods

{

public static string Render(this ViewResult result, Controller controller)

{

controller.ViewData.Model = result.Model;

try

{

using (var sw = new StringWriter())

{

var viewResult = ViewEngines.Engines.FindPartialView(controller.ControllerContext, result.ViewName);

var context = new ViewContext(controller.ControllerContext, viewResult.View, result.ViewData, result.TempData, sw);

viewResult.View.Render(context, sw);

return sw.GetStringBuilder().ToString();

}

catch (Exception e)

{

return e.ToString();

}

Mock a private Method of class with a private Constructor

I have the following class, I use this class to assign functionality to another class. How do I mock the "PrivatelyDoWork" method using JustMock? I also want to Assert that the "DoPrivateWork" has been call for a certain number of occurances. Thanks.

internal class MyClass

{

private MyClass()

{

}

private void PrivatelyDoWork(string stringValue)

{

}

Temporary Static Mocking

I have some legacy code I am trying to migrate to Just Mock. There are some static objects that many of our older tests reference. I am slowly starting to re-write these tests with Static Mocking.

How can I have some of my tests use the mocked static while others continue using the old un-mocked static? Ideally, I would like some code I can put either at the end of my test, in a using statement, or in my test/fixture teardown that would revert the static object to its original state and cause the next call to it to execute the static constructor/initialization.

Something like this:

class MyClass
{
    public static int SomeStatic { get; private set;}
    static MyClass()
    {
        SomeStatic = 15;
    }
}
 
[Test]
public void foo()
{
    using (Mock.SetupStatic(typeof(MyClass), Behavior.Strict, StaticConstructor.Mocked));
    {
        Mock.Arrange(() => MyClass.SomeStatic).Returns(5);
        Assert.AreEqual(5, MyClass.SomeStatic);
    }
    Assert.AreEqual(15, MyClass.SomeStatic);
}

Unable to debug ASP.NET projects with Q3 2013

The temporary solution was to uninstall the version Q3 2013 of JustMock.

I rised a ticket here: http://feedback.telerik.com/Project/105/Feedback/Details/63749-unable-to-debug-asp-net-projects-with-q3-2013

I hope the problem will be fixed soon.

Unit testing a private method that loads a public property

I am testing a private method using JustMock and that works fine. However, to verify the method worked correctly, I need to pull the value of a public property that the private method loads. Basically, the constructor loads a set of configuration XML documents and exposes them through a public property of a configuration class.

So I am able to mock the private method that is executed from the contrstructor (InitializeFile) and it works fine. But I want to create a couple of asserts to verify the public property has the values that it should and that it is not empty. But since I have mocked a private method, I don't have a way to get to the public property. At least I do not see how to do that and none of the examples I have come across this show this.

Here's the test I have come up with so far. The GetProperty() fails becuase the property is a public property and I have mocked up a PrivateAccessor. So what do you have to do to mock a priviate method, but also have access to get the value of a public property... or can you with JusMock?

public void LoadConfiguartionSettingsTest()

{

// Arrange

var inst = PrivateAccessor.ForType(typeof(Configuration));

var xdoc = (XDocument)inst.CallMethod("InitializeFile");

// Act

inst.CallMethod("LoadConfiguartionSettings", new object[] { xdoc });

var resp = inst.GetProperty("AppSettings"); // This fails... I guess because it is a public property.

// Assert

Assert.IsNotNull(resp);

Assert.IsInstanceOfType(resp, typeof(List<AppSetting>));

}

Error while trying to Mock DataServiceQuery<T>

Hi I am trying to mock a Property that is of type DataServiceQuery<EntityLock> like this:

locksViewModel.Query = Mock.Create<DataServiceQuery<EntityLock>>();

as soon as I try to execute this line I am getting the next exception:

Initialization method Tgw.Wcs.Windows.U.Test.ComponentTests.Modules.LoadCarriers.LocksViewModelTest.TestInitialize threw exception. System.TypeInitializationException: System.TypeInitializationException: The type initializer for 'System.Data.Services.Client.DataServiceQuery`1' threw an exception. ---> System.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

I have also tried not to Mock this property and initialize it in the constructor of the class that I am trying to test:

here is part of the constructor:

public LocksViewModel(IEnumerable<LoadCarrier> selectedLoadCarriers, ILoadCarrierRepository loadCarrierRepository)

{

if (selectedLoadCarriers != null && loadCarrierRepository != null)

{

DataContext = loadCarrierRepository.DataModelServiceContext;

Query = (DataServiceQuery<EntityLock>)loadCarrierRepository.GetEntityLocks(selectedLoadCarriers.Select(x=>x.Id));

And here is part of my InitializeTest:

IQueryable<EntityLock> entityLocks = Mock.Create<IQueryable<EntityLock>>();
 
           LoadCarrierRepository loadCarrierRepository = Mock.Create<LoadCarrierRepository>();
           loadCarrierRepository.DataContext = Mock.Create<ClientDataModelServiceContext>();
            
 
           Mock.Arrange(() => loadCarrierRepository.GetEntityLocks(Arg.IsAny<IEnumerable<Guid>>())).ReturnsCollection(entityLocks);
           Mock.Arrange(() => loadCarrierRepository.GetLockReasons()).ReturnsCollection(new List<string> { "fooLockReason1", "fooLockReason2" });
           locksViewModel = new LocksViewModel(new ObservableCollectionEx<LoadCarrier>() { loadCarrier }, loadCarrierRepository);
And I am getting this exception:

Initialization method Tgw.Wcs.Windows.U.Test.ComponentTests.Modules.LoadCarriers.LocksViewModelTest
.TestInitialize threw exception. System.InvalidCastException: System.InvalidCastException: 
Unable to cast object of type 'Castle.Proxies.IQueryable`1Proxy' to type 
'System.Data.Services.Client.DataServiceQuery`1[Tgw.Wcs.Windows.Data.UIModel.EntityLock]'..

Test not working well when we try to parallel it

Hi,

I have a test that have a Parallel.For in it. If I remove the Parallel.For, works fine, but if I try to do it in a parallel way I get an exception like if the Mocks where not applied.

Exception:

Test method Tgw.Wcs.StorageAndInventory.U.Test.Core.LoadCarrierManagerTest.UpdateLoadCarrierLocksLoadCarrier threw exception:
System.AggregateException: One or more errors occurred. ---> System.InvalidOperationException: No connection string named 'StorageAndInventoryContext' could be found in the application config file.

Is like after the first thread is launched the rest of them cannot get the Mocked object...

[TestInitialize]

public void Initialize()

{

loadCarrierManager = new LoadCarrierManager();

loadCarrier = new LoadCarrier { Name = "LC1" };

//Creates a number of elements

loadCarriers = CreateLoadCarriers(numberOfLoadcarriers);

//First Mock the SIS Context

storageAndInventoryContext = Mock.Create<StorageAndInventoryContext>(() => new StorageAndInventoryContext("Non"),

Behavior.CallOriginal);

//Mock the GetContext so it will return out Mocked element

Mock.Arrange(() => StorageAndInventoryContextProvider.GetContext())

.Returns(storageAndInventoryContext);

Mock.Arrange(() => storageAndInventoryContext.InventoryAccountSet.OfType<LoadCarrier>())

.ReturnsCollection(loadCarriers);

}

[TestMethod]

[TestCategory(TgwTestingCategories.ServiceTest)]

[WorkItem(11126)]

public void UpdateLoadCarrierLocksLoadCarrier()

{

Parallel.For((long)0, 3, i =>

{

using (var scope = new UnitOfWorkScope())

{

for (int lcCount = numberOfLoadcarriers-1; lcCount > 0; lcCount--)

{

string lcName = string.Format("LC{0}", lcCount);

LoadCarrierChangeSet loadCarrierChangeSet = new LoadCarrierChangeSet();

var lcToUpdate = loadCarrierManager.GetLoadCarrierData(lcName);

loadCarrierChangeSet.Locks = new LockChangeSet("fooReason", "fooDescription");

loadCarrierManager.UpdateLoadCarrier(lcToUpdate.Name, loadCarrierChangeSet);

}

scope.Complete();

}

});

using (new UnitOfWorkScope())

{

var badEntityLocksDescriptions =

storageAndInventoryContext.InventoryAccountSet.OfType<LoadCarrier>()

.Select(x => x.EntityLocks.Where(y=>y.Description == "fooReason"));

Assert.AreEqual(100, badEntityLocksDescriptions.Count());

}

Upgraded to 2013.3.1015.0 - Multiple Tests Failing.

We upgraded to Visual Studio 2013 and along with it, the latest version of JustMock (2013.3.1015.0)

After the upgrade, 3 of our tests started failing.

The code that kills it:

var sp = new ClaimsPrincipal();
Mock.Arrange(() => sp.FindFirst("CONTROLLER/CONTROLLER")).Returns(new Claim("CONTROLLER/CONTROLLER", "0"));
Mock.Arrange(() => System.Threading.Thread.CurrentPrincipal)
.IgnoreInstance()
.Returns(sp);

The exception it throws:

Telerik.JustMock.MockException: Type System.Threading.Thread does not support mocking of static members due to limitations in CLR.

It blows on the bolded line, which worked previously...

We have attached JustMock to 2013 CodeCoverage/Intellitrace profiler options, but there is no Visual Studio 2013 Profiler selectable as there was with VS2012. (I believe the elevated permissions are working as expected, because all of our other .Net mscorelib tests are passing fine)

Any thoughts?

Breaking all tests

For 11/140 tests we are using JusMock. I just installed the latest version. When I enable the profiler and run all test though, they all break. I have VS2010 ultimate and VS2013 ultimate. This is the error I am getting.

Test Name: BackButtonTest

Test FullName: BBA.POS.Test.NewTransactionViewModelTest.BackButtonTest

Test Source: c:\TFS\POS\POSApp\v3-Phase2\Source\BBA.POS.Test\NewTransactionViewModelTest.cs : line 995

Test Outcome: Failed

Test Duration: 0:00:00.7688022

Result Message:

Test method BBA.POS.Test.NewTransactionViewModelTest.BackButtonTest threw exception:

System.TypeInitializationException: The type initializer for '.' threw an exception. ---> System.ArgumentNullException: Value cannot be null.

Parameter name: field

TestCleanup method BBA.POS.Test.NewTransactionViewModelTest.MyTestCleanup threw exception. System.TypeInitializationException: System.TypeInitializationException: The type initializer

for '.' threw an exception. ---> System.ArgumentNullException: Value cannot be null.

Parameter name: field.

at BBA.POS.Test.NewTransactionViewModelTest.MyTestCleanup() in c:\TFS\POS\POSApp\v3-Phase2\Source\BBA.POS.Test\NewTransactionViewModelTest.cs:line 99

When i disable the profiler, all of the non-justmock tests pass but the 11 fail. When I check in my code the build server says all tests pass, so I know it's just something on my machine causing the problem. Does anyone know how to fix this?
