[openstack-dev] [QA][ec2-api][nova] Future of Tempest ec2 tests

Hi Matthew,

I'd like to provide you with some info in regard to standalone EC2 API part.
I can't claim clear understanding of tempest development directions but 
here are the things to take in account about EC2 API:

1. Standalone EC2 API carry all of its tests including previously 
tempest ones as in-project functional tests.
2. As far as I recall all of the original tempest EC2 API tests are 
covered. (not true for all S3 tests, though)
3. We're trying to use RefStack for checking EC2 API compatibility as 
well. And RefStack works with tempest tests so we'd have to somehow 
connect our tests with RefStack.

Most probably I'll be in Tokyo if you'd want to discuss it in more details.

Best regards,
   Alex Levine
