[tarantool-patches] Re: [PATCH v3] test: need to wait for upstream/downstream status

[Alexander Turenko <alexander.turenko@tarantool.org>]

It worth to remove fiber.sleep() before the status / message checks.

I also have updated the API in
https://github.com/tarantool/test-run/pull/163 to make it extensible. So
now status / message checks looks so:

 | test_run:wait_upstream(other_id, {status = 'stopped', message_re = 'Missing'})
 | test_run:wait_upstream(other_id, {status = 'follow', message_re = box.NULL})

Aside that the patch looks good for me.

Pushed to master and 2.1.

WBR, Alexander Turenko.
