Question

How can I test for this exception as returned from a WCF call?

I have this error class.

[Serializable]
public class PermissionDenied_Error : Exception
{
    public PermissionDenied_Error() : base("You are not approved.") { }
}

In my Service, I am throwing it.

if (notApproved)
{
    throw new FaultException<PermissionDenied_Error>(new PermissionDenied_Error()
              , new FaultReason("Permissions Denied!"));
}

In my test, I am expecting it.

[Test]
[ExpectedException(typeof(FaultException<PermissionDenied_Error>))]

Current result is:

Expected: System.ServiceModel.FaultException`1[[PermissionDenied_Error
    , Project.API, Version=1.0.4318.24332, Culture=neutral, PublicKeyToken=null]]
 but was: System.ServiceModel.FaultException : Permissions Denied!

Your PermissionDenied_Error should be a data contract. It should not be derived from Exception.

Also,you need to place the FaultContractAttribute on your operation contract so that the client knows to expect an exception.

public interface IAccess
{
        [OperationContract]
        [FaultContract(typeof(PermissionDenied_Error))]
        DtoResponse Access(DtoRequest request);
}
