Hi All,

I am facing challenge in retreieving lightning email templates folder in vscode. I am aware that in order to retrieve classic email templates folder package.xml is like this:
<types>
        <members>foldername</members>
        <members>foldername/templatename</members>
        <name>EmailTemplate</name>
</types>

When I use this package.xml for lightning email templates folder, I am able to retrieve the templates but the folder throws error:
=== WARNING: The following metadata isn’t in your org. If it’s not new, someone deleted it from the org.
Entity of type 'EmailTemplate' named 'foldername' cannot be found

The difference b/w lightning email template folder and classic email template folder is type:

For classic folder it is Email but for lightning it is coming as EmailTemplate

please help me how to write a test class in knowledge__DataCategorySelection and knowledge articles
