How about we keep a checklist of release tests? I know we already send a
mail on dev on what needs to be tested for each RC, but I need that is too
abstract. For core developers of Airavata I think there should be test
cases predefined (a test document if you may). Since we have several core
developers in the list we can atleast decide upon what must be tested and
make sure that each test case is covered by atleast one developer for a RC.

A TC should be something internal IMO. But when we are going for a release
it should be alpha, beta and then RC releases. I think it need not be
mandatory for the RMs to do pre-evaluation of the builds other than making
sure all the unit tests and integration tests pass. Once an RC is confirmed
of release quality I think we can follow the actual release cycle from the
trunk itself with since its in a code freeze anyway.
