multiple method calls to a mocked object throws and exception

Hi,
I am trying to mock db access using JustMock. I do have an interface defined and created a mock object from the interface. I then arranged a method to return false for any argument. After arranging the mock object on the second call with unique arguments a null reference exception is thrown. The code snippet below shows what I am trying to do:

IDBAccess fakeDBAccess = Mock.Create<IDBAccess>();
List<ModelType1> fakeModelType1 = GetFakeModelModelType1();
Mock.Arrange(()=> fakeDBAccess.GetModelType1ForPrimaryKey(Arg.Is<long>(1))).Returns(fakeModelType1[0]);
Mock.Arrange(() => fakeDBAccess.GetModelType1ForPrimaryKey(Arg.Is<long>(2))).Returns(fakeModelType1[1]);
List<fakeModelType2> fakeModelType2 = new List<fakeModelType2>();
Mock.Arrange(() => fakeDBAccess.GetModelType2ForPrimaryKey(Arg.IsAny<long>())).Returns(fakeModelType2);
Mock.Arrange(() => fakeDBAccess.GetModelType1Status(Arg.IsAny<ModelType1>())).Returns(false);
ClassUnderTest OUT = new ClassUnderTest(fakeDBAccess );

On debugging the above code try to call fakeDBAccess.GetModelType1Status() with two different values say fakeModelType[0] and fakeModelType[1] (in the watch window) the first call succeeds and returns false but the second call fails with a null reference exception. The order of calls do not matter. It is always the second call that throws the null reference exception. Can you please confirm whether this is a bug or not. If this is a bug can you please suggest a work around?

Mocking references inside of a mock

Trying to write tests for some legacy code and I have a question about mocking fields or other references inside a mock. In the code below, "Assert.IsNotNull(member.Rsa)" will fail because the mocked constructor of member hasn't created anything. Currently I've solved the problem by creating a separate mock and assigning to it, but is this really the best way to do this?

var testChallengeData = new ChallengeData();

testChallengeData.responseList = new Response[] {new Response(), new Response(), new Response()};

var member = Mock.Create<Member>(Constructor.Mocked);

var rsa = Mock.Create<Vendors.RSA>(Constructor.Mocked);

Mock.SetupStatic(typeof (Settings), StaticConstructor.Mocked);

Mock.Arrange(() => Settings.getBool(Arg.AnyString)).IgnoreInstance().Returns(false);

Mock.Arrange(() => Settings.getInt(Arg.AnyString)).IgnoreInstance().Returns(3);

Mock.Arrange(() => rsa.CurrUserStatus).IgnoreInstance().Returns(Vendors.AdaptiveAuthRef.UserStatus.UNVERIFIED).OccursOnce();

Mock.Arrange(() => rsa.HasChallengeQuestions).IgnoreInstance().Returns(true).OccursNever();

Mock.Arrange(() => member.challengeQuestions).IgnoreInstance().Returns(testChallengeData);

Mock.Arrange(() => member.hasChallengeQuestions).CallOriginal();

member.Rsa = rsa;

Assert.IsNotNull(member.Rsa);

Assert.IsTrue(member.hasChallengeQuestions);

rsa.Assert();

Mock.Assert(() => Settings.getBool(Arg.AnyString), Occurs.Once());

Exception with mocked object using NUnit and JustMock

Hi All, We have a requirement where we have to use NUnit to write test methods and JustMock for mocking the application.
Our application is exposing WCF services and the unit tests will be written to test the WCF Operations. We are using VS 2013.In our application we are using Dependency injection while calling the Constructor i.e. the parameters to the Constuctor are created using Dependency injection. Please refer below sample

public NetworkService(IDbContextFactory<NetworkDbContext> contextFactory, IEventBus eventBus, HostService hostService, UserManagementService userManagementService)
         {
             _contextFactory = contextFactory.ThrowIfNull("contextFactory");
             _eventBus = eventBus.ThrowIfNull("eventBus");
             _hostService = hostService.ThrowIfNull("hostService");
             _userManagementService = userManagementService.ThrowIfNull("userManagementService");
       }

I tried mocking using Telerik Justmock to create the objects of ContextFactory, EventBus etc. but the object created using mocking was of type Proxy of actual object rather than the object itself i.e. Proxy of IEventBus rather than IEventBus.The _contextFactory object is used to create a context like below

using (var ctx = _contextFactory.Create())

But as the object is of type Proxy(Object) I am unable to create the context ctx in above scenario. Hence the controls goes to the Service but
when it tries to use context object ctx, it throws an "Null Reference exception" and hence the testing fails.

Can anyone please suggest if there is any issue with the above and suggest on alternate solution using NUnit and JustMock.

Any help will be highly appreciated. Thanks in advance.

Call Private method with ref parameters

I am using CallMethod to call a private method and it works great, but I need to call a method that has some ref parameters, Is it possible to do that
Also i would like to compare the values in the ref after the method execution finishes, basically instead of returning one value method is manipulating multiple values and i need to Assert all of them

Thanks
vikas

JustMockTestRunner

I have enabled the code activity workflow in a TFS build that runs unit tests. My understanding is that JustMockTestRunner uses MSTest.exe to execute them. Is it possible to use VSTest.Console.exe instead?

Does InSequence work for ArrangeSet?

I have a mocked class which has a bool property BoolProperty.
I have a class under test with a method under test which first sets BoolProperty to true, and then to false.
I wish to set up an arrangement which tests that these two calls are made in the correct order, which I have done as follows:

    mockedClass.ArrangeSet(x => x.BoolProperty = true).InSequence();
    mockedClass.ArrangeSet(x => x.BoolProperty = false).InSequence();

This passes the test fine. However, if I reverse the order:

    mockedClass.ArrangeSet(x => x.BoolProperty = false).InSequence();
    mockedClass.ArrangeSet(x => x.BoolProperty = true).InSequence();

this *also* passes.
Shouldn't this second arrangement cause the test to fail?

I am using JustMock 2014.1.1424.1

Testing kickstart help

Hi there,

I'm new to JustMock and I'm looking into writing unit tests. Below i have copied the code i'm trying to test and will also copy what i have so far for unit testing. Looking at the test covarage within Visual Studio i aren't testing the catch exceptions and i don't know how to do this. Most my tests are structured this way and any help to get me moving again will be appreciated.

[HttpGet]

[Route("api/DealBuilder/GetSession")]

public IHttpActionResult NewVersion(string sessionId)

{

try

{

if (!String.IsNullOrEmpty(sessionId))

{

try

{

return Ok(dealbuilderRepository.GetTemplateAndXml(new Guid(sessionId)));

}

catch (Exception ex)

{

return InternalServerError(ex);

}

else

{

return BadRequest("No Session ID was passed.");

}

catch (Exception ex)

{

// TODO: logger.Error(ex.Message, ex);

return InternalServerError(ex);

}



This is what i have so far for tests on my code above.



[TestMethod]

public void NewVersion()

{

var repo = Mock.Create<IDealBuilderRepository>();

var controller = new DealBuilderController(repo);

Mock.Arrange(() => repo.Equals(Arg.IsAny<String>()));

var result = controller.NewVersion(Arg.IsAny<String>());

Mock.Assert(repo);

}

[TestMethod]

public void GetNewVersionFail()

{

var repo = Mock.Create<IDealBuilderRepository>();

var controller = new DealBuilderController(repo);

Mock.Arrange(() => repo.Equals(Arg.IsAny<Guid>())); // .Returns(null);

var result = controller.NewVersion(new Guid().ToString()) as InternalServerErrorResult ;

Mock.Assert(typeof(InternalServerErrorResult));

}

Thanks again,

Tommy

BaseApiController apicontroller = container.Resolve<BaseApiController>();

Mock.NonPublic.Arrange(apicontroller, "setUtcOffset").IgnoreArguments().IgnoreInstance();

var config = new HttpConfiguration();

var route = config.Routes.MapHttpRoute("DefaultApi", "api/{controller}/{id}");

var routeData = new HttpRouteData(route, new HttpRouteValueDictionary { { "controller", "Mobile" } });

MultipartFormDataContent formDataContent = new MultipartFormDataContent();

formDataContent.Add(new StringContent(Guid.NewGuid().ToString()), name: "EntityID");

controller.Request = request;

controller.Request.Properties[HttpPropertyKeys.HttpConfigurationKey] = config;

var result = await controller.addUpdateMessage();

{

throw new HttpResponseException(HttpStatusCode.BadRequest);
