Changing the JustMock default shortcuts inside Visual Studio

Recently, there were several client reports about interference between some of the default JustMock shortcuts inside Visual Studio. The conflicting shortcuts were the ones, used for enabling and disabling the JustMock profiler (JustMock.EnableProfiler and JustMock.DisableProfiler). The default keys for these commands were:

Ctrl + Alt + [
Ctrl + Alt + ]

It appeared these combinations are commonly used for typing the following symbols: { or [ and } or ]. The issue is possible to appear only on a certain keyboard layouts (e.g. Italian, Canadian-French, etc.)

This is already fixed in the upcoming JustMock official release. We have changed the shortcuts to not interfere with the user environment in such ways. The new shortcuts for enabling and disabling the profiler will be:

Ctrl + Shift + [ - for JustMock.EnableProfiler
Ctrl + Shift + ] - for JustMock.DisableProfiler

As a workaround, until the next version is out, you can change the shortcuts from inside Visual Studio by performing the following:

From Tools menu, go to Options;
Navigate to Environment > Keyboard;
Inside the "Show commands containing" text box write: JustMock
Then find JustMock.EnableProfiler and JustMock.DisableProfiler and remove or change their shortcuts as you want (you can also change the rest of the JustMock shortcuts if required). Note that, you will need to remove the old shortcuts in order to disable them.

Mocking a low layer

Hi,

suppose my applicaiton contains several layers, the lowest one is a DAL (Data Access Layer) interfacing with a DB.
Now, I want to unit-test a method of a class in the upper layer which eventually calls a method in the DAL. Naturally, I want to mock only the DB, not the mid-layer classes.
How should I go about unit-testing a high-layer method as mentioned above?

Thanks,
Michael

Create Mocks in a Testing Base Class

Hi, I am running into a small issue with justmock. I am using nunit as my testing framework which allows base classes with multiple TestFixtureSetup methods when running a single test. I will create and inject my common mocks in the base class TestFixtureSetup method. Then my test class(inheriting the base class) will do the arranging and testing.

The issue is when the method being mocked is called, it acts like the arrange never excuted. I can verify that all the code ran in the order expected, but my mocked methods are just returning nulls.

Below I have a simple example of what I'm trying to explain.

[TestFixture]

public abstract class TestBase

{

public IClientService ClientService;

[TestFixtureSetUp]

public void InitFixture()

{

ClientService = Mock.Create<IClientService>();

}

[TestFixture]

public class ClientServiceTests : TestBase

{

[Test]

public void Test()

{

Mock.Arrange(() => ClientService.Retrieve(Arg.AnyLong))

.Returns(() => new Client());

var client = ClientService.Retrieve(0);

Assert.IsNotNull(client);

}

This does work when the test class has a TestFixtureSetUp of its own and calls the base class setup method, but the base class setup method cannot have the TestFixtureSetUp attribute. Does this mean that the arrange has to execute within the same fixture as the create?
Is there a better way to utilize a base class in this manner? Is this intended?

On a side note, this method was working a couple days ago when I had checked my code in. I will revert my tests to see if i stumbled upon some way to get this to work, I may have had the attributes in just the right places possibly?

Mocking Method with out-param

class and method

public class A

{

public static bool TryGet<T>(string key, out T obj)

{

....

}

usage

public static object AMethod(string key)

{

object values;

if (A.TryGet(key, out values))

{

return values;

}

return null;

}

now i want to write a test for method AMethod and mock A.TryGet. How can I do that? I tried different approaches, but wasnt able to create a mock of the TryGet extension. I want to set the "obj" variable in the "TryGet" method do different values depending on the passed key (using "Returns" or "DoInstead")

Mocking System.Enum

hello,
I try to create a mock for System.Enum. That works for all public static methods of the System.Enum class (i.e. Enum.GetValues). But I have no idea how to set up the mock for the ToString() method of the Enum object.
(all C# .NET)

method:

public static void TestThis(ListControl ctrl, Type enumType, Enum enumItem= null)

{

int[] itemValues = Enum.GetValues(enumType).ToArray<int>();

string[] itemNames = Enum.GetNames(enumType);

string s = enumItem.ToString();

}

mock:

Mock.SetupStatic(typeof(Enum), Behavior.Strict);

Mock.Arrange(() => Enum.GetValues(Arg.IsAny<Type>())).Returns(new int[] { 1, 2, 3 });

Mock.Arrange(() => Enum.GetNames(Arg.IsAny<Type>())).Returns(new string[] { "1", "2", "3" });

//--- this causes an exception (Cannot create mock for type due to CLR limitations.)

Enum e = Mock.Create<Enum>();

Mock.Arrange(() => e.ToString()).IgnoreArguments().IgnoreInstance().Returns("2"

);

//---



//--- in that case null is returned instead of "2"; compiler never steps into the mocked "returns"


TestEnum e = Mock.Create<TestEnum>();
Mock.Arrange(() => e.ToString()).IgnoreArguments().IgnoreInstance().Returns("2");

//---


DropDownList ddlTestList = new DropDownList();

TestThis(ddlTestList, typeof(TestEnum), TestEnum.Empty)

Arranged static method is not arranged on different thread

I am trying to test my application that uses Tasks. I have arranged a static method, if I call that method right after arranging it, I get the Mocked return value. But, if I call the method from a task, the method is not mocked.
I am running on version 2011.2.713.2 as my subscription has run out, and since this is a static method, I cannot use the free edition.

I do have JustMock enabled in the VS menu Telerik->JustMock->Enable JustMock
I managed to reproduce the problem with a simple example:

using System;

using System.Threading;

using System.Threading.Tasks;

using System.Linq;

using Microsoft.VisualStudio.TestTools.UnitTesting;

using Telerik.JustMock;

namespace TestMockingStatic

{

public class ClassWithStatic

{

public static int NumGot = 0;

public static int GetANumber(int foo, int bar)

{

throw new NotImplementedException();

}

[TestClass]

public class UnitTest1

{

public void GetValue()

{

Task.Factory.StartNew(() =>

{

ClassWithStatic.NumGot = ClassWithStatic.GetANumber(5, 10);

});

}

[TestMethod]

public void TestMethod1()

{

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

Mock.Arrange(() => ClassWithStatic.GetANumber(Arg.AnyInt, Arg.AnyInt)).Returns(42);

Assert.AreEqual(42, ClassWithStatic.GetANumber(5, 10), "Mocked Method did not return expected result");

GetValue();

SpinWait.SpinUntil(() => ClassWithStatic.NumGot > 0, 20000);

Assert.AreEqual(42, ClassWithStatic.NumGot, "Mocked method called via TASK, did not return correct value");

}

Any help would be great,
Todd

Capture matcher value at runtime for .Returns

Hi there. I'm trying to figure out if there's a way to reference the runtime value of a matcher for use in a Returns call. This seems like a pretty straightforward question, but I wasn't able to find quite what I'm wanting in the documentation, so apologies if I missed something obvious. Regardless, here's the call I'm trying to make.

service.Arrange<Employee

>(emp => emp.LoadByName(Arg.AnyString)).Returns(data.employees.Where(e => e.Name == /* whatever the value matched by Arg.AnyString was */));

Is there another method I should be calling to accomplish the same thing, or is there simply a way to reference the matcher's value?

Some SharePoint faking questions

Hello I have a question about SharePoint Faking.
in my Class unter Test I have an method that use following code.


 public Guid CreateNewSite(String siteUrl, string newSite)
{


using

(SPSite site = new SPSite(siteUrl))

{

if (!site.AllWebs.Names.Contains(newSite))

{

return site.AllWebs.Add(newSite, newSite, "New Website", 1033, "STS#1", true, false).ID;

}


}

and this is my Testcode:

SPSite fakeSite = Mock.Create<SPSite>();

Mock.Arrange(() => fakeSite.AllWebs.Names).ReturnsCollection<string>(new[] { "nonExistsWeb" });

Mock.Arrange(() => fakeSite.AllWebs.Add(Arg.AnyString, Arg.AnyString, Arg.AnyString, (uint

)Arg.AnyInt, Arg.AnyString, Arg.AnyBool, Arg.AnyBool).ID).Returns(SomeGuid);

 
Guid actual = spListCreator.CreateNewSite("http://local", "SomeSite");

But this will not work. I get this error:
System.IO.FileNotFoundException: The Web application at http://local could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application.

Why?

Regards

questions about using Justmock

Hello, I have some questions about unit testing with Justmock.

I have this very simple method (Share Point code):

Code:

public Guid CreateNewSite(String siteUrl, string newSite)
       {
           if (!(string.IsNullOrEmpty(newSite) || string.IsNullOrEmpty(siteUrl)))
           {
               using (SPSite site = new SPSite(siteUrl))
               {
                   if (!site.AllWebs.Names.Contains(newSite))
                   {
                       return site.AllWebs.Add(newSite, newSite, "New Website", 1033, "STS#1", true, false).ID;
                   }
               }
           }
           return Guid.Empty;
       }

1 question.
Is it ok, that I test the methods return (Guid). I mean I test the contract of the method "CreateNewSite". If the site that should be created not exist, and the parameters are not empty, the new site will be created and a Guid != Guid.Empty will be returned. Otherwise return Guid.Emtpy.

Or should I test, that the method site.AllWebs.Add(newSite, newSite, "New Website", 1033, "STS#1", true, false).ID; was called with the right parameters?

2 question.
How can I unit test the void methods (interaction testing) with Justmock.
For example this code:

public void AddSplistItemToList(SPWeb web, Guid listId, String listItemTitle)
        {
            if (!(listId == Guid.Empty || listId == Guid.Empty || string.IsNullOrEmpty(listItemTitle)))
            {
                SPList list = web.Lists[listId];
                SPListItem item = list.Items.Add();
                item["Title"] = listItemTitle;
                item.Update();
            }
        }

Because the AddSplistItemToList is void, I want to test, that item["Title"] would set correctly (value from listItemTitle parameter). How I can test and fake this with Justmock?

I hope my questions are not too confused :)

Mock.IsProfilerEnabled is False when running tests

Hello,

I'm trying to use the licensed JustMock version for developing some unit tests.

I was having some issues when running existing unit tests (created by other people on the project), as the error: "Telerik.JustMock.MockException: Profiler must be enabled to mock/assert target ..." kept appearing over and over. I tried registering the dlls for Profiles and it did succesfully, but I'm still getting the same problem. If I open the JustMock configuration, no Profile is available. If I check the Telerik menu in VS 2010, the profiler is enabled. These is the result of the process and environment variables I get:

ProcessID=7428
JUSTMOCK_INSTANCE=5716
COR_ENABLE_PROFILING=
COR_PROFILER=

(last two variables in blank) Then I set the variables as you indicated in: http://www.telerik.com/community/forums/justmock/general-discussions/profiler-must-be-enabled-to-mock-error.aspx to:

JUSTMOCK_INSTANCE = 1
COR_ENABLE_PROFILING = 1
COR_PROFILER = {B7ABE522-A68F-44F2-925B-81E7488E9EC0}

Close VS, reopen again. When reopening the project, I get first the following error: vs error.png Then, I close it and then I get the following error: vs error 2.png I realized this doesn't happen if I don't set the COR_ENABLE_PROFILING variable (VS doesn't show that error again if I delete that variable). Also, when trying to run some of the tests using JustMock, VS closes unexpectedly. What can I do to fix it? How can I make JustMock work with VS 2010? Thanks, Pablo.
