Testing when using Shortcuts Input

If I want a shortcut to use the value “Shortcut Input”. Is there any way to test this without creating another shortcut which calls the Shortcut in question?

For development and debugging purposes it would be nice if there was a way to set the value for Shortcut Input.

Put an if at the start to check for it coming in (e.g. count the number of items being passed in), and if not either ask you for some data, and/or default some data in. Use the result of that if subsequently.
