Uh, no.  If you track testing, and receive new packages after the release,
you will NOT be (guaranteed) able to go back to stretch.  Downgrading
has never been supported, and is manual and messy at best, impossible
at worst.

If you want to play around with testing in a reversible fashion, you
should set up either a chroot or a virtual machine.  (Or a separate
bootable partition, or a separate computer.)  Otherwise, once you bring
in something like libc6 post-release, you are *committed* to the next
testing cycle.
