I'm using/implementing JustMock for the first time. I've watched the webnair, but I can't seem to get the Mocked object working properly. We have a full paid version of JustMock.

I have an internal database access layer object, "OperationsData", and an "ComponentException" object with a private constructor. I'm trying to write the unit test method for the Persist method of the ComponentException object. The unit tests are all in a separate project so the internal class and the private constructor use a "_Accessor".

When I run the unit test it complains that OperationsData connection string isn't instantiated. Why isn't it just using the mocked object and return the expectedExceptionId that I want? Thanks.

This is the ComponentException.Persist() ...

public void Persist()

{

try

{

OperationsData data = new OperationsData();

this.ExceptionId = data.PersistException(this.Id, this.ExceptionCode, this.ComponentName, this.SeverityIndicator.ToString(), this.ProcessName, this.BusinessExceptionDetail, this.StackTrace);

}

catch (Exception ex)

{...}

}

This is the UnitTest...

[TestMethod()]

public void SuccessfulPersistTest()

{

/// Arrange

long expectedExceptionID = 12345;

long ID = 678901;

string exceptionCode = string.Empty;

string componentName = string.Empty;

string severityIndicator = string.Empty;

string processName = string.Empty;

string businessExceptionDetail = string.Empty;

string stackTrace = string.Empty;

OperationsData_Accessor operationsData = new OperationsData_Accessor();

operationsData.Arrange(od => od.PersistException(ID, exceptionCode, componentName, severityIndicator, processName, businessExceptionDetail, stackTrace))

.IgnoreInstance()

.Returns(expectedExceptionID);

///Action

ComponentException_Accessor target = new ComponentException_Accessor();

target.Persist();

///Assert

Assert.AreEqual(expectedExceptionID, target.ExceptionId);

operationsData.Assert();

}

PS. I also tried...

OperationsData_Accessor operationsData = Mock.Create<OperationsData_Accessor>(Constructor.Mocked);

Does any one know how to do FutureMocking on an Internal Class using the InternalClass_Accessor?

This doesn't work...(using MSTest)

OperationsData_Accessor od = Mock.Create<OperationsData_Accessor>(Constructor.Mocked);

Mock.NonPublic.Arrange(od, "PersistException", new object[] { _ID, _exceptionCode, _componentName, _severityIndicator, _processName, _businessExceptionDetail, _stackTrace })

.IgnoreInstance()

.DoNothing()

.Returns(_expectedExceptionId)

.OccursOnce();

I'm guessing it has something to do with the different between "InternalClass" and "InternalClass_Accessor"

Hello Robert,

Thank you for contacting our forums.

As you have noted, it is very possible that the issue is present due to the difference between the InternalClass and its accessor (InternalClass_Accessor).

To assist you further, I will need a sample project reproducing the matter. You should be able to attach it to the message with your next reply. It will help me to investigate the issue in details and provide a solution faster.

I hope this is doable for you.

Thank you for the cooperation in advance.
