Clear out test orders?

Is there a preferred way to clear out TEST orders?

I am reluctant to edit anything directly in the database tables ... Thx!

Why not use the delete button on the orders listing ?

True, then can I reset the starting number?

Yes, you can change the auto_increment value of the order table. There are some explanations on how to change the auto_increment there:

Note that if you use paypal and that you already have orders registered there. You might get the same error message as on that documentation because paypal cannot accept two orders with the same id.
