[Qemu-devel] [PATCH 14/14] iotests: Enhance 223, 233 to cover 'qemu-nbd --list'
Posted by Eric Blake 6 years, 10 months ago 
Any good new feature deserves some regression testing :)
Coverage includes:
- 223: what happens when there are 0 or more than 1 export,
proof that we can see multiple contexts including qemu:dirty-bitmap
- 233: proof that we can list over TLS, and that mix-and-match of
plain/TLS listings sanely
