Subject: tests: Factor out common code in qapi output tests
X-Git-Tag: v2.7.1~209^2~4
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;ds=sidebyside;h=23d1705f425ca847f11d92e4363cd7f67f369fd8;p=mirror_qemu.git

tests: Factor out common code in qapi output tests

Create a new visitor_get() function to capture common
actions taken in collecting output from an output visitor,
to make it easier to refactor the output visitors in a
later patch.
