How to iterate over a ShimListItemCollection (Shim of Microsoft.SharePoint.Client.ListItemCollection) with C#?

Question

I am trying to write a unit test method for the following code:

public static void MoveItems(ShimListItemCollection listItems){
foreach (ListItem item in listItems)
{
// Do Something
}
}

When call ACT in Arrage, Act and Assert methodology, I am passing in a Shim of that ListItemCollection as creating one just to test the function seems not feasible.

// Act
Program.MoveItems(new ShimListItemCollection());

However, this throws an error of null pointer exception and fails to iterate over the ShimListItemCollection as one would expect.

How do I get around this?

Thanks in advance.

Hi @Puneeth, C ,
You can refer to the following code to iterate over a sharepoint ListItemCollection

using (ClientContext clientContext = new ClientContext("http://MyServer/sites/MySiteCollection"))  
{  
List targetList = clientContext.Web.Lists.GetByTitle("List Name");  
   
CamlQuery oQuery = CamlQuery.CreateAllItemsQuery();  
   
ListItemCollection oCollection = targetList.GetItems(oQuery);  
clientContext.Load(oCollection);  
clientContext.ExecuteQuery();  
   
foreach (ListItem oItem in oCollection)  
{  
Console.WriteLine(oItem["Title"].ToString());  
}  
}
