This is the first time I've had reason to use a release still designated 
as "testing". [In the past I've had bandwidth constraints limiting me to 
purchased DVD sets.]

1. At _this point_ in the release cycle is there reason to prefer URLs 
specifying "stretch" over ones with "testing"?

2. Is there a document (or blog or ??) targeted at someone using a 
"testing" release for the first time. My interest relates to the move 
from MySQL to Mariadb - I've already been pointed to links to the fine 
details of the change. I'm asking if there something with a broad 
perspective on dealing with any testing release.
