Testing the "Thank You" page after successful order

[EvanGR]

Hello,

I want to tweak the "Thank you" page, after a successful order (and similar pages)... without going through a test order every time.
Is this possible?

Thanks

PS. What other such pages should I be aware of?

I presume you mean change orderdone.php ? 
If not yet overridenthe file is in  /components/com_virtuemart/views/cart/tmpl/ 
but if your template uses overrides check in /templates/your-template/html/com_virtuemart/cart/

I make changes like that on a local copy of the site with a simplified checkout - no shipping selection and basic payment plugin set to charge nothing (like COD)  so I can check layout etc.

Thank you very much!

Is it possible to go straight to that page, using an existing order id? (simulating a successful order)
It would save time.
