Updating JustMock 2013-2014

Hello. I am having some difficulty getting an update to JustMock working for our existing unit test library.

Details:
We were on 2013.2.611 and have upgraded to 2014.2.811.1.
We use TFS Build to run unit tests (under MSTest). I have already set up the code activity (including environmental settings) from the last version based on the JustMock guide and it was working with 100% success rate on the old version.
I updated the library to latest one from the new JustMock installation.

Builds completes and most of the JustMock related unit tests are failing with many similar error messages such as:
Telerik.JustMock.MockException: Arranging the return value of a constructor call is not supported.
Telerik.JustMock.MockException: Can not instantiate proxy of class: Could not find a parameterless constructor.

Are there any major changes between the versions that could be causing this? Something I forgot to update?

AutoMock list dependency

Hi, I've been having some trouble passing a list to a class that is the instance of a MockingContainer.

01.using System.Collections.Generic;

02.

03.namespace JustMock_AutoContainer

04.{

05. public interface IWorker

06. {

07. void DoSomething();

08. }

09.

10. public interface IService

11. {

12. string Moo { get; }

13.

14. void DoLotsOfThings();

15. }

16.

17. public class Service : IService

18. {

19. private readonly IList<IWorker> workers;

20.

21. public Service(IList<IWorker> workers, string moo)

22. {

23. this.workers = workers;

24. this.Moo = moo;

25. }

26.

27. public string Moo { get; private set; }

28.

29. public void DoLotsOfThings()

30. {

31. foreach (var worker in this.workers)

32. {

33. worker.DoSomething();

34. }

35. }

36. }

37.}

And the test class is:

01.using JustMock_AutoContainer;

02.using Microsoft.VisualStudio.TestTools.UnitTesting;

03.using System.Collections.Generic;

04.using Telerik.JustMock;

05.using Telerik.JustMock.AutoMock;

06.using Telerik.JustMock.Helpers;

07.

08.namespace JustMock_AutoContainer_Tests

09.{

10. [TestClass]

11. public class ServiceTest

12. {

13. #region Fields

14. private MockingContainer<Service> container;

15. #endregion

16.

17. #region Test Configuration

18. [TestInitialize]

19. public void CreateTargetContainer()

20. {

21. this.container = new MockingContainer<Service>();

22. }

23. #endregion

24.

25. [TestMethod]

26. public void DoLotsOfWork_TwoWorkers_AllWorkersCalled()

27. {

28. // Arrange

29. var provider1 = StubWorker();

30. var provider2 = StubWorker();

31. var target = this.CreateTarget(provider1, provider2);

32.

33. // Act

34. target.DoLotsOfThings();

35.

36. // Assert

37. Assert.AreEqual("moo", target.Moo);

38. provider1.Assert(p => p.DoSomething()); // Fails here :(

39. provider2.Assert(p => p.DoSomething());

40. }

41.

42. #region Support Methods

43. private static IWorker StubWorker()

44. {

45. var dataTraceProvider = Mock.Create<IWorker>();

46. return dataTraceProvider;

47. }

48.

49. private IService CreateTarget(params IWorker[] providers)

50. {

51. this.container

52. .Bind<IList<IWorker>>()

53. .ToConstant((IList<IWorker>)providers);

54.

55. //TODO: fix line above; the list is not being picked up in the target.

56. // JustMock seems keen on giving us a list with one and only one item in it, rather than

57. // what we've registered above.

58. this.container

59. .Bind<string>()

60. .ToConstant("moo");

61.

62. return this.container.Instance;

63. }

64.

65. #endregion

66. }

67.}

The registration on line 51 seems to be ignored. Is there something else I should be doing?

Using ternary operator in definitions of args

Hi,
The following code does not work...

public interface IService2

{

string MethodWithArgs(string one, string two);

}

[TestMethod]

public void SubbingMethodwithArgs_DontCareAboutValues_StubbedMethodCalled()

{

var service = StubMethodWithArgs("rv");

var actual = service.MethodWithArgs("a", "b");

Assert.AreEqual("rv", actual);

}

private static IService2 StubMethodWithArgs(string returnValue, string expectedOne = null, string expectedTwo = null)

{

var service = Mock.Create<IService2>();

service

.Arrange(s => s.MethodWithArgs(

null != expectedOne ? Arg.Is(expectedOne) : Arg.AnyString, // null coalesance (??) doesn't work either

null != expectedTwo ? Arg.Is(expectedTwo) : Arg.AnyString))

.Returns(returnValue);

return service;

}

Is this a limitation of JustMock?

Regards,

Nick

AutoMock Abstract Class

Hi, is it possible to use MockingContainer<T> where T is an abstract class, such as the following:

01.public abstract class SimpleBaseClass

02.{

03. private readonly IService service;

04. protected SimpleBaseClass(IService service)

05. {

06. this.service = service;

07. }

08. public void CallServiceMethod()

09. {

10. this.service.DoLotsOfThings();

11. }

12.}

I've tried the following, the latter works as expected.

01.[TestMethod]

02.public void AutoMock_AbstractClass_CallsMethod()

03.{

04. var container = new MockingContainer<SimpleBaseClass>();

05. //container.Bind<SimpleBaseClass>().ToMock(); // Still fails :(

06. container.Arrange<IService>(s => s.DoLotsOfThings()).MustBeCalled();

07.

08. container.Instance.CallServiceMethod();

09.

10. container.AssertAll();

11.}

12.

13.[TestMethod]

14.public void CreateMock_AbstractClass_CallsMethod()

15.{

16. var service = Mock.Create<IService>();

17. var target = Mock.Create<SimpleBaseClass>(Behavior.CallOriginal, service);

18.

19. target.CallServiceMethod();

20.

21. service.Assert(s => s.DoLotsOfThings());

22.}

I've tried configuring with AutoMockSettings using CallOriginal, but it just seems like NInject always jumps in and fails to find a suitable constructor.

Call a private method in a test.

Can I (or does it make sense) call a private method from a unit test?

The setup code is getting really big to test a little piece of code within a private method. Instead it seems like it might be a good idea to just mock the parameters and then call the private method as follows (incomplete since I don't know if this works). I want to call a piece of the private implementation with defined parameters and then test for results. This would be a replacement for having to walk through the code in the debugger over and over again.

// Arrange mock data.

var service = new ScheduledTaskService();

var start = new DateTime(2014, 08, 15);

var due = start.Next(DayOfWeek.Thursday);

var assignee = new SimpleEmployeeView {Id = 1, LastNameFirstName = "Test User", IsActive = true};

var taskModel = new ScheduledTaskModel()

{

DaysBeforeDue = 5,

Start = start,

End = due,

Title = "Test Subject",

Description = "Test Description",

Id = 999

};

// This is the method I would like to call somehow if possible.

Mock.NonPublic.Arrange(service, "CreateTaskForAssignee", taskModel, assignee);

// Ignore db changes.

var database = Mock.Create<Database>();

Mock.Arrange(database, d => d.SaveChanges()).DoNothing();



// TODO test for changes in the result.

Should be very basic...

I figure this out... but I know it won't be very complicated.
I am calling this method and I want to mock the string "alpha"

public void Request()
{
if (string.isNullOrEmpty(alpha))
{
Do somthing bad
}
else
{
Do somthing good
}

Pretty much I want alpha to be mocked so that it passes the if statement and goes on to do something good.

JustMock support for Windows Phone 8.1 WinRT app

Hi,

Does JustMock support Windows Phone 8.1 WinRT apps? I tried referenced Telerik.JustMock.dll in my project and wrote a sample test, it compiles fine but I get the below runtime error:

UnitTests.SetupTest threw exception. System.IO.FileNotFoundException: System.IO.FileNotFoundException: Could not load file or assembly 'System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified..

Is it a Justmock not supporting WP 8.1 WinRT issue? Or am I missing something?

Thanks,
Tarun

Profiling a Test which uses JustMock

I'm using Visual Studio 2013.

I've configured JustMock to "run together with JustMock" all detected profilers, however I'm seeing this exception:

mocking CustomeAttributes

I am trying to mock this for a unit test... I need help getting all items in here mocked. what I have done does not work and it seems like that the mocks never get hit when they are supposed to. I know that a few of the items are part of our library and may not work on your machines but if you could help please get it on track and I can run it and straighten it out if needed.

public static string GetEnumDisplayName<T>(string enumName)
        {
            string retVal = null;
            MemberInfo memberInfo = typeof(T).GetMember(enumName).FirstOrDefault();
            if (memberInfo != null)

            {
                object[] customAtts = memberInfo.GetCustomAttributes(typeof(IDisplayName), false);
                if (customAtts != null && customAtts.Length > 0)
                {
                    retVal = ((IDisplayName)customAtts[0]).DisplayName;
                }
                //
                if (retVal == null)
                {
                    customAtts = memberInfo.GetCustomAttributes(typeof(GeneralDisplayNameAttribute), false);
                    if (customAtts != null && customAtts.Length > 0)
                    {
                        retVal = ((GeneralDisplayNameAttribute)customAtts[0]).DisplayName;
                    }
                }
            }
            return retVal;
        }
