I have a Transfer
class, simplified it looks like this:
public class Transfer
{
public virtual IFileConnection source { get; set; }
public virtual IFileConnection destination { get; set; }
public virtual void GetFile(IFileConnection connection,
string remoteFilename, string localFilename)
{
connection.Get(remoteFilename, localFilename);
}
public virtual void PutFile(IFileConnection connection,
string localFilename, string remoteFilename)
{
connection.Get(remoteFilename, localFilename);
}
public virtual void TransferFiles(string sourceName, string destName)
{
source = internalConfig.GetFileConnection("source");
destination = internalConfig.GetFileConnection("destination");
var tempName = Path.GetTempFileName();
GetFile(source, sourceName, tempName);
PutFile(destination, tempName, destName);
}
}
The simplified version of the IFileConnection
interface looks like this:
public interface IFileConnection
{
void Get(string remoteFileName, string localFileName);
void Put(string localFileName, string remoteFileName);
}
The real class is supposed to handle a System.IO.IOException
that is thrown when the IFileConnection
concrete classes loses connectivity with the remote, sending out emails and what not.
I would like to use Moq to create a Transfer
class, and use it as my concrete Transfer
class in all properties and methods, except when the GetFile
method is invoked - then I want it to throw a System.IO.IOException
and make sure the Transfer
class handles it properly.
Am I using the right tool for the job? Am I going about this the right way? And how would I write the setup for that unit test for NUnit
?
