Problem facing with collection objects using typemock

Hi there,
I am facing issue with collection objects while writing unit test using typemock.
actually i want to add atleast one item in collection to make it enter into the loops.
It will be great if anyone can help on same.
Below given are the 3 sample which are facing same kind of problem.

sample 1:
//newsList is a splist object
SPListItemCollection collection = newsList.GetItems(queryRegion);

if (collection.Count > 0)
{
SPListItem item = collection[0];
//do something with item here....

}

and

sample2:

//newsList is a splist object
SPListItemCollection collection = newsList.GetItems(query);
foreach (SPListItem item in collection)
{
//do something with item here....
}


also


//dttable is datatable containing n no of rows

foreach (DataRow drow in dttable.Rows)
{
//do somthing with drow....

}
