Cloning from physical standby

This question might seem a bit obvious for many of you, I'm just trying to figure out which would be the best way to clone a database using the physical standby (so i don't need to touch prod) into a test environment. I was thinking about the following steps:

• Stopping the physical standby
• Copying the files across to the test environment
• Restarting the physical standby (so it gets in sync again)
• Recreating the control file in test and starting up the db.

Would this, roughly, be correct?

Thanks for your help.

David
