And one question I will have when we discuss this is regarding this
statement: "Green cell - tests ran successfully,"

Currently we don't have community consensus around the use of the
statement "tests ran successfully" regarding third party ci systems.
This is as statement, you recall, we had discussed at the third party
meeting when we talked about driverlog.

18:46:02 <krtaylor> but what does CI tested really mean? just running
tests? or tested to pass some level of requirements?
http://eavesdrop.openstack.org/meetings/third_party/2014/third_party.2014-06-16-18.00.log.html

Using a statement to convey success prior to having a definition from
the community about what the statement means will create confusion in
the community and frustration from folks, including myself, who are
willing to have the conversation about what it means, who feel
circumvented by this second use of a phrase which implies a decided
meaning where none yet exists. Please participate in conversations
around the definition of phrases of success and failure regarding third
party systems and point to the logs where consensus is reached prior it
its use in future.

In addition to attending the third party meeting, please attend the
infra meeting or the qa meeting, and hopefully meetings that include
programs that have interactions with third party ci systems including
nova, neutron, and cinder (if there are other programs interacting with
third party ci systems please attend the third party meeting so I know
about you).

Thanks Ilya, I look forward to our future discussions,
Anita.
