Hi,

I am new to justmock, bear with me if I have some basic questions wrong.

We have few unit tests that run fine when I run them locally, but when I checkin them in TFS then it fails the gated-checkin.

I know this can be caused from a range of reasons, but I have reason to believe that one of the mocked method is not getting mocked in the server.

Here is how the code looks,

public void My_Failing_Test()

{

Test_Class_Accessor target = new Test_Class_Accessor();

target.DataLayer = GetMockLayer();

// Set up data

Test_Class mockTest = new Test_Class();

Mock.NonPublic.Arrange<bool>(mockPharm, "MockedPrivateMethod", ArgExpr.IsAny<String>(), ArgExpr.IsAny<String>(), ArgExpr.IsAny<DateTime>()).IgnoreArguments().IgnoreInstance().Returns(false);

target.UnderTestPrivateMethod();

//Asserts

}

UnderTestPrivateMethod has a call to MockedPrivateMethod

private static DataLayer GetMockLayer(......)

{

Features mockFeatures = Mock.Create<Features>(Constructor.NotMocked, Behavior.CallOriginal);

mockFeatures.someThing = new SomeThing{.....};

DataLayer mockLayer = Mock.Create<DataLayer>(Constructor.NotMocked, Behavior.CallOriginal);

mockLayer.TwoTier_Initialize();

Mock.Arrange(() => mockLayer.Features).Returns(mockFeatures);

return mockLayer;

}

I suspect for some reason both the mockFeatures.someThing and MockedPrivateMethod are not getting mocked.

Is there something wrong with what I am doing?
If someone has faces similar problem before, please let me know.

Appreciate the time, thanks

Using JustMock outside of test runners/ visual studio

I'm wondering whether I am simply trying to achieve the impossible, but.....

I have successfully mocked up some legacy code and able to run my tests. I have then built a simple WPF app to utilise the same mocking approach and publish the results (without using test fixtures)

However, when I try to run the app outside of visual studio, I get the following exception:

Telerik.JustMock.Core.ElevatedMockingException

Message=Cannot mock 'System.String get_blah()'. The profiler must be enabled to mock, arrange or execute the specified target.
Source=Telerik.JustMock

I have checked the event viewer and the profiler is enabled.

Is this issue simply that this will never run outside of Visual Studio/any other test runner?

Ideally, we would like to be able to create a suite of automated regression testing apps for non-devs to use.

Kind Regards

Difficulty Mocking Private Generic Method

Hi all,

I have the following generic method in my class:

1.private T ValidateApiResponse<T>(Document response) where T : ResponseBase

2. {

3. }

My test method looks like this:

01.[TestMethod]

02. public void CardCaptureRequest_CallsCreateRequest()

03. {

04. //Arrange

05. var methodCalled = false;

06. var facadeSettings = MockFacadeSettings("http://localhost", "logfile", 1, 2, "proxy");

07. var authSettings = MockAuthenticationSettings("clientName", "password");

08. var facade = Mock.Create<DatacashFacade>(Behavior.CallOriginal, new object[] { facadeSettings, authSettings });

09. var document = Mock.Create<Document>();

10. var ccResponse = new CardCaptureResponse

11. {

12. Status = 1,

13. DatacashReference = "refNo",

14. Information = "Info",

15. MerchantReference = "merchRef",

16. RedirectUrl = "http://localhost/",

17. Success = true

18. };

19.

20. Mock.NonPublic.Arrange<Document>(facade, "CreateRequest")

21. .DoInstead(() =>

22. {

23. methodCalled = true;

24. }).Returns(document);

25. Mock.NonPublic.Arrange<Document>(facade, "SendRequest")

26. .IgnoreInstance().Returns(document);

27.

28. Mock.NonPublic.Arrange<CardCaptureResponse>(facade, "ValidateApiResponse", document)

29. .Returns(ccResponse);

30.

31. //Act

32. facade.CardCaptureRequest(1, "", 2, "", "", "");

33.

34. //Assert

35. Assert.IsTrue(methodCalled);

36. }

Line 28 is attempting to Mock the private method call.

However, the test fails with the following: Method 'ValidateApiResponse' with the given signature was not found on type .......

Any ideas??

Unable to Mock when using Entity Functions

I have been attempting to learn how we can mock out calls to entity framework in our project. I ran into this problem where we are using EntityFunctions.TruncateTime. The error says: this function can only be invoked from linq to entities. If this should be supported help on what i'm doing wrong, if its not then i guess we are out of luck for those scenarios.

from audit in _context.Audits

where audit.DTS < EntityFunctions.TruncateTime(mydate)

select audit

var fakeEntities = Mock.Create<SomeDBEntities>();

var audits = GetAudits();

Mock.Arrange(() => fakeEntities.Audits).ReturnsCollection(audits);

var target = new ReportRepository(fakeEntities);

var result = target.test(DateTime.Now);

Assert.AreEqual(2, result.Count());

Thanks
John

JustMock on Windows 10 Preview Unit Test

Hi,

I want to use JustMock Lite on Windows 10 SDK Preview: Unit Test App - UAP.

"Install-Package : Could not install package 'JustMock 2015.1.224.3'. You are trying to install this package into a project that targets '.NETCore,Version=v4.5.1', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author."

Does anybody manage to re-build JustMock and use it in Win 10 Preview?

Thanks for support

How can you mock a private method call that uses a non accessible enum as a method parameter?

Here is an example of what I'd like to mock up?

namespace ExternalAssembly

{

internal enum HintArg { Flag1,Flag2,Flag3}

public class ExternalClass

{

private int MethodToMock(string name, HintArg hint, out string result)

{

result ="I want to override this";

return 0;

}

In this example what I'd like to have is a setup that will call the original MethodToMock on everything except when I have a specific name match?

I have something along the lines of:

string mockName="mockName";

string mockResult ="new result";

Mock.NonPublic.Arrange(typeof(ExternalClass),"MethodToMock",mockName,ArgExpr.IsAny<HintArg>(),ArgExpr.Out<string>(newResult).Returns(0);

I'm just not sure how to specify the arg expression when the type is an internal that my invoking assembly is not friends with?

Mock EF6 DBContext

Downloaded the trial of JustMock since so many of the problems I have been facing are supposed to be addressable with it. I'm attempting to Mock an EF 6.1.3 DBContext. I have can build a test that runs directly against the DB and it works fine, but when I run against the Mocked Context I get an exception.

To be clear I am using JustMock version 2015.3.929.5 also per the documentation I downloaded JustMock.EntityFramework from Nuget version 1.0.1. The Nuget installed incorrectly into the project and tried to explicitly target JustMock 2014.1.1424.1, but I corrected the config file back to the currently referenced version as mentioned above.

Here is my code.

public class Account

{

public int Id { get; set; }

[Required]

public string ExternalId { get; set; }

public string AccountTimeZone { get; set; }

public string FipsCode { get; set; }

public bool DVREnabled { get; set; }

public bool Enabled { get; set; }

public double CreditLimit { get; set; }

public int SdStreams { get; set; }

public int HdStreams { get; set; }

[Column(TypeName="DateTime2")]

public DateTime CreatedTimeUTC { get; set; }

[Column(TypeName = "DateTime2")]

public DateTime LastUpdateTimeUTC { get; set; }

public string CreatedBy { get; set; }

public string UpdatedBy { get; set; }

public AccountStatus AccountStatus { get; set; }

public List<Device> Devices { get; set; }

public List<SubscriberGroup> SubscriberGroups { get; set; }

public List<AccountValue> AccountValues { get; set; }

public SubscriberInfo SubscriberInfo { get; set; }

public Device RecordingDevice { get; set; }

[Required]

public Tenant Tenant { get; set; }

public List<Phone> Phones { get; set; }

public List<AccountHistory> AccountHistory { get; set; }

}

public class Tenant

{

public int Id { get; set; }

public string TenantName { get; set; }

public string TenantDescription { get; set; }

public string MediaroomVersion { get; set; }

public TenantConfiguration TenantConfiguration { get; set; }

public List<Account> Accounts { get; set; }

public List<Device> Devices { get; set; }

public List<ChangeEvent> ChangeEvents { get; set; }

}

public class EmptyAccount

{

public void CreateEmptyAccountInConductor(Account newAccount, int tenantId, string requestedBy, UnitOfWork uow)

{

var tr = new TenantRepository(uow);

var tenant = tr.Find(tenantId);

tenant.Accounts.Add(new Account(){ExternalId = newAccount.ExternalId, CreatedBy = requestedBy});

tr.InsertOrUpdate(tenant);

uow.Save();

}

public class TenantRepository : ITenantRepository

{

private readonly ConductorContext _context;

public TenantRepository(UnitOfWork uow)

{

_context = uow.Context;

}

public Tenant Find(int id)

{

return _context.Tenants.Find(id);

}

public void InsertOrUpdate(Tenant entity)

{

if (entity.Id == default(int))

{

_context.Entry(entity).State = EntityState.Added;

}

else

{

_context.Entry(entity).State = EntityState.Modified;

}

public class ConductorContext : DbContext

{

public ConductorContext()

{

base.Configuration.ProxyCreationEnabled = false;

}

public DbSet<Account> Accounts { get; set; }

public DbSet<AccountHistory> AccountHistories { get; set; }

public DbSet<AccountTemplate> AccountTemplates { get; set; }

public DbSet<AccountValue> AccountValues { get; set; }

public DbSet<ChangeEvent> ChangeEvents { get; set; }

public DbSet<Device> Devices { get; set; }

public DbSet<DeviceValue> DeviceValues { get; set; }

public DbSet<Phone> Phones { get; set; }

public DbSet<SubscriberGroup> SubscriberGroups { get; set; }

public DbSet<SubscriberInfo> SubscribersInfo { get; set; }

public DbSet<Tenant> Tenants { get; set; }

public DbSet<TenantConfiguration> TenantConfigurations { get; set; }

}

public class UnitOfWork : IUnitOfWork<ConductorContext>

{

private readonly ConductorContext _context;

public UnitOfWork()

{

_context = new ConductorContext();

}

public UnitOfWork(ConductorContext context)

{

_context = context;

}

public int Save()

{

return _context.SaveChanges();

}

public void Dispose()

{

_context.Dispose();

}

public ConductorContext Context

{

get { return _context; }

}

Direct to DB test that works.

[Test]

public void CreateEmptyAccountInConductor4()

{

// Arrange

Database.SetInitializer(new DropCreateDatabaseAlways<ConductorContext>());

var ctx = new ConductorContext();

var fixture = new Fixture();

var account = fixture.Build<Account>()

.Without(p => p.Id)

.Without(p => p.Tenant)

.Without(p => p.AccountHistory)

.Without(p => p.AccountValues)

.Without(p => p.Devices)

.Without(p => p.Phones)

.Without(p => p.SubscriberGroups)

.Without(p => p.SubscriberInfo)

.Without(p => p.RecordingDevice)

.Without(p => p.CreatedTimeUTC)

.Without(p => p.LastUpdateTimeUTC)

.Create();

var tenant = fixture.Build<Tenant>()

.With(p => p.Id, 1)

.With(p => p.MediaroomVersion, "V2")

.Without(p => p.Accounts)

.Without(p => p.Devices)

.Without(p => p.ChangeEvents)

.With(p => p.TenantConfiguration, new TenantConfiguration())

.Create();

ctx.Tenants.Add(tenant);

ctx.SaveChanges();

// Act

var sut = new EmptyAccount();

sut.CreateEmptyAccountInConductor(account, 1, fixture.Create<string>(), new UnitOfWork(ctx));

ctx.Dispose();

// Assert

ctx = new ConductorContext();

// Force entity to load into context.

var tenantAfter = ctx.Tenants.Find(1);

var accountAfter = ctx.Accounts.Find(1);

Assert.AreEqual(account.ExternalId, ctx.Tenants.Find(1).Accounts.Single(p => p.ExternalId == account.ExternalId).ExternalId);

}

Mocked Context that fails with a NullReferanceException in the InsertOrUpdate method of TenantRepository.

[Test]

public void CreateEmptyAccountInConductor3()

{

// Arrange

var ctx = Mock.Create<ConductorContext>().PrepareMock();

var fixture = new Fixture();

var account = fixture.Build<Account>()

.Without(p => p.Id)

.Without(p => p.Tenant)

.Without(p => p.AccountHistory)

.Without(p => p.AccountValues)

.Without(p => p.Devices)

.Without(p => p.Phones)

.Without(p => p.SubscriberGroups)

.Without(p => p.SubscriberInfo)

.Without(p => p.RecordingDevice)

.Without(p => p.CreatedTimeUTC)

.Without(p => p.LastUpdateTimeUTC)

.Create();

var tenant = fixture.Build<Tenant>()

.With(p => p.Id, 1)

.With(p => p.MediaroomVersion, "V2")

.With(p => p.Accounts, new List<Account>())

.Without(p => p.Devices)

.Without(p => p.ChangeEvents)

.With(p => p.TenantConfiguration, new TenantConfiguration())

.Create();

var tenantList = new List<Tenant>()

{

tenant

};

ctx.Tenants.Bind(tenantList);

// Act

var sut = new EmptyAccount();

sut.CreateEmptyAccountInConductor(account, 1, fixture.Create<string>(), new UnitOfWork(ctx));

// Assert

Mock.Assert(() => ctx.SaveChanges(), Occurs.Once());

}

My assertion test for the Mocked Context is never even reached in the failing test. At this point I assume I'm doing something wrong. Any idea how I can get this to work because I don't want to be creating dropping my database over and over to run my test. This is just one of many I need to write like this.

ConfigurationManager.AppSettings not all values

Hi,

I am using JustMock for some app.config settings:

Mock.Arrange(() => ConfigurationManager.AppSettings["MyAppSettingKey1"]).Returns("MyAppSettingValue1");

Mock.Arrange(() => ConfigurationManager.AppSettings["MyAppSettingKey2"]).Returns("MyAppSettingValue2");

Mock.Arrange(() => ConfigurationManager.AppSettings["MyAppSettingKey3"]).Returns("MyAppSettingValue3");

However, if I do this, other values that are not explicitly mocked are not available:

var myValue = ConfigurationManager.AppSettings["MyAppSettingKeyNotMocked"])

throws a System.NullReferenceException

Is there a better way to mock Configuration.AppSettings?

Pass DialogResult to Callback method in MessageBox.SHow

Hi,

I have a MessageBox.Show method, which has a CallBack action associated with it. I want to Pass a Mocked parameter to that action, which would eventually execute the action statements based on Parameter passed.

Action<DialogResult> callback = (result) =>

{

if (result == DialogResult.Yes)

{

//Do something here

}

};

MessageBox.Show("Are you Sure?","Test App",DialogButton.YesNo, DialogImage.Question,callback);

I tried something like below, but it did not work.

Mock.Arrange(() => dialog.Show(Arg.AnyString, Arg.AnyString,DialogButton.YesNo, DialogImage.Question, Arg.IsAny<Action<DialogResult>>())).

DoInstead((Action<DialogResult> action) =>

{

action.Invoke(DialogResult.Yes);

});

I want to execute the Original callback, with a mocked DialogResult.

How can we do that?

Thanks in Advance,

Sagar

Telerik.JustMock.Core.ElevatedMockingException issue

Hello guys!

I get a Telerik.JustMock.Core.ElevatedMockingException when I run: Mock.Arrange(() => _client.GetAsync(Arg.IsAny<string>())).Returns(ShowMeTheMoney());

static async Task<HttpResponseMessage> ShowMeTheMoney()
{
HttpRequestMessage httpRequest = new HttpRequestMessage();
httpRequest.SetConfiguration(new HttpConfiguration());
HttpResponseMessage response = httpRequest.CreateResponse(HttpStatusCode.OK, new List<SmsDTO>() { new SmsDTO()});
return response;
}

[TestMethod]
public void GetAll_NullResultTes3t()
{
//Assert.IsTrue(Mock.IsProfilerEnabled);
_client = Mock.Create<HttpClient>();
_controller = new SmsController(new Persistence(_client));
_controller.Request = new HttpRequestMessage();
Mock.Arrange(() => _client.GetAsync(Arg.IsAny<string>())).Returns(ShowMeTheMoney());
IEnumerable<SmsDTO> actualResult = _controller.GetAll();
CollectionAssert.AllItemsAreNotNull(actualResult.ToList());
}

I use VS2015 Enterprise and I have disabled IntelliTrace(Tools>Options>IntelliTrace: Uncheck the Enable IntelliTrace checkbox). Also I enabled the profiler from the JustMock Menu.

I get the following in Event logs:

Could you please help?
