Hi Josef,
as Patrick already mentioned, the simplest solution would be to inject
the DataGenerator into the DataConsumer:
public class DataConsumer
{
private readonly DataGenerator dg;
public DataConsumer (DataGenerator dataGenerator)
{
dg = dataGenerator;
}
public int GetNameLength ( )
{
return dg.GetName().Length;
}
}
To be able to mock the DataGenerator with Rhino Mocks you also have to
introduce an interface for the DataGenerator or at least make the
method GetName() 'virtual':
public class DataGenerator
{
public virtual string GetName()
{
return "My Name";
}
}
You will have a little more code, but a much better design (less
coupling). You get the possibility to test your DataConsumer
thoroughly, which can include test for error cases (E.g.: How does the
DataConsumer behave, when the DataGenerator throws an exception?)
Kind Regards
Sven
