Making sure a method does something using justmock

Hi there,

So I have been looking at some just mock examples but can't put together how we would verify that calling a particular method did something, i.e. called another method. Here is the snippet I want to test.

public void Initialize()

{

//Initialize the vendor mapping module

container.RegisterInstance<VendorMappingViewModel>(new VendorMappingViewModel(eventAggregator));

I want to make sure that contianer.RegisterInstance is called when Initialize is called. I can't test a variable cause it isn't like it stores something somewhere... Is there an example of this somewhere?

Thanks!!!

Am I setting up these tests correctly?

I am attempting to use JustMocks to unit test our BLL and DAL layer classes, but I am having trouble getting it to work. I suspect that the issue is that I am not setting up the tests properly for the code. Here is a simple example that follows the pattern of the code under test.

First the object

//BO

public class Person

{

public int ID {get; set;}

public string name {get; set;}

public int age {get; set;}

public bool isMale {get; set;}

}

Then the DAL

//DAL

public class PersonDbo

{

public static BO.Person GetPersonByID(int ID)

{

BO.Person result = new BO.Person();

//Helper method our project uses

Database db = Helper.CreateDbConnection();

using (DbCommand dbCommand = db.GetStoredProcCommand("dbo.Select_Person_ByID"))

{

db.AddInParameter(dbCommand, "@PersonID", DbType.Int32, ID);

using (IDataReader r = db.ExecuteReader(dbCommand))

{

if (r.Read())

{

result.ID = r.GetInt32(r.GetOrdinal("PersonID"));

result.name = r.GetString(r.GetOrdinal("Name"));

result.age = r.GetInt32(r.GetOrdinal("Age"));

result.isMale = r.GetBoolean(r.GetOrdinal("Is_Male"));

}

else

return null;

return result;

}

Then the BLL

//BLL

public class PersonManager

{

public static BO.Person GetPerson(int ID)

{

BO.Person result = PersonDbo.GetPersonByID(ID);

return result;

}

And finally the test

//Test

[TestClass()]

public class PersonManagerTest

{

[TestMethod()]

public void GetPersonTest()

//Arrange

Person tom = new Person() { ID = 7, name = "Tom", age = 34, isMale = true};

Mock.SetupStatic<PersonManager>(Behavior.Strict);

Mock.Arrange(() => PersonManager.GetPerson(7)).Returns(tom).MustBeCalled();

//Act + Assert

Assert.AreEqual(PersonManager.GetPerson(7), tom);

}

Am I doing these right?

ArrangeSet/MustBeCalled Not Working

Hello,

I've started to play around with JustMock and so far I really like the API and the features. I've found one issue so far that's preventing me from switching over to JustMock, though. ArrangeSet with MustBeCalled does not appear to be working. Here's a code sample:

    
            [TestClass] 
        
            public class Test 
        
            { 
        
                [TestMethod] 
        
                public void TestFoo() 
        
                { 
        
                    var mockFoo = Mock.Create<Foo>(); 
        
                    Mock.ArrangeSet(() => mockFoo.A = 1).MustBeCalled(); 
        
                    //mockFoo.A = 2; 
        
                    Mock.Assert(mockFoo); 
        
                } 
        
            } 
        
            public class Foo 
        
            { 
        
                public int A { get; set; } 
        
            }

The TestFoo test passes even though the mockFoo.A set accessor was not called. If I uncomment the mockFoo.A = 2 line, it still succeeds even though the value (2) doesn't match what was specified in the ArrangeSet Action (1).

Is this a known issue or am I missing something? This test was run in .NET 4.0 under VS2010.

Thanks,
Jack L

Ho to mock HtmlPage.Document.QueryString (Silverlight)?

Hi @All,

I'm new using JustMock. It seems to be very different to other Frameworks like RhinoMock ;-)

I want to test the gathering of parameters passed via QueryString in the Url of the Silverlight hosting page. I have to use HtmlPage.Document.QueryString to do this, but how can I mock this?

I need to mock HtmlPage.Document.QueryString
I need to return a custom Dictionary<string, string>

I couldn't found anything in the documentation about that

Mock RIA services

Hi,

I've got the following test:

        [TestMethod]
        public void PayrollViewModel_CallConstructor_DisplayNameSet()
        {
            // Arrange
            var context = Mock.Create<PersonnelDomainContext>();
            var session = Mock.Create<ISession>();
            var eventAgg = Mock.Create<IEventAggregator>();
            var viewModel = new PayrollViewModel(context, session, eventAgg);
 
            // Act
            viewModel.GetPersonnel();
 
            // Assert
            Assert.AreEqual("Personnel List", viewModel.DisplayName, "Display name is incorrect");
        }

Basically, I'm trying to Mock the DomainContext that is generated by RIA Services. I'd like all the service calls to the services on the server side to be mocked so they are not run/called.
I'm getting the following error:

TestMethod: PayrollViewModel_CallConstructor_DisplayNameSet
TestClass: PayrollViewModelTests
Result: Failed

Exception:
Could not create a mock from the specified target.
   at Telerik.JustMock.MockManager.CreateInstance(Type target, Container container, Boolean profilerEnabled)
   at Telerik.JustMock.MockManager.SetupMock(Type target, Behavior behavior, Boolean static)
   at Telerik.JustMock.MockManager.CreateInstance()
   at Telerik.JustMock.Mock.Create(Type target, Behavior behavior, Object[] args)
   at Telerik.JustMock.Mock.Create(Type target, Object[] args)
   at Telerik.JustMock.Mock.Create[T]()
   at PayrollPrototype.Client.Personnel.Tests.PayrollViewModelTests.PayrollViewModel_CallConstructor_DisplayNameSet()

Failed

I suspect it is because the DomainContext is sealed. So how do I mock it, I'm supposed to be able to mock just about anything with justmock. (pardon the pun). I've been reading about mocking for some time but am still weak in the implementation. Need more practice. I keep seeming to hit errors when I try to mock anything.

thanks,
Stephen

How can I verify the order of method calls?

Hi,

I am new to mocking and started looking at JustMock. But I can't seem to figure out how I can verify the order of method calls.

For an example to assert that OnStart() was called exactly once before OnStop() was called exactly once on my mock object.

Is this possible?

Sincerely, Peter

Entity Model and ToList()

I am running into some exceptions when I try and mock some property calls from an entity framework model.

var fakeEntities = Mock.Create<SomeEntities>(Constructor.Mocked);

Mock.Arrange(() => fakeEntities.SomeObjectSet.Count()).Returns(5);

Mock.Arrange(() => fakeEntities.SomeObjectSet.ToList()).Returns(someList);

The first arrange works fine, but the ToList() call results in an ArgumentNullException.

It looks like it is actually trying to convert 'SomeObject' to a list instead of getting mocked. Any Ideas?

Mock.Initialize

I am having similar issues as those in this thread:
http://www.telerik.com/community/forums/justmock/general-discussions/mocks-failing-to-work-correctly-in-large-test-runs.aspx

Basically, I have some unit tests that work fine when i run them alone, together however, the first test passes, then the rest fail. It seems as if the first tests mocks are successfully intercepted, and then the subsequent tests mocks are not.

The solution it seems is the Mock.Initialize function. Does Mock.Initialize apply to class methods that are not static? If so, is there an example I could take a look at?

Bad Class Token in Elevated mode

Hello,

I'm currently using the trial version to investigate if we want to use JustMock as our new mocking framework.
We especially like the 'Elevated' mode where we can mock mscorlib classes, etc.

However when I try to run the justmock tests (MSTest in VS2008) the Visual Studio test runner stops and throws the following error:
"Unit Test Adapter threw exception: Bad class token.."

This is my dev setup:
Windows XP
Visual Studio 2008
.NET Framework 3.5 SP1
JustMock trial

Is there a solution for this problem? If so, please let me know asap so that I can further investigate this tool.

Thanks in advance for your help.
Ruud

Mocking Private Members

public class Class1
    {
        private bool Helper()
        {
            return true;
        }

        public bool TestMe()
        {
            if (Helper()) return true;

            return false;

        }

    }

[TestMethod]
        public void TestMethod1()
        {

            var class1 = Mock.Create<Class1_Accessor>();
            Mock.Arrange(() => class1.Helper()).Returns(false);
            Mock.Arrange(() => class1.TestMe()).CallOriginal();
            bool actual = class1.TestMe();
            Assert.IsFalse(actual);

        }

Why is the class1.Helper() mock not mocking, it is executing the method. We have legacy code which has this going on everywhere so I want mock internal calls.

Thanks.
