The exact pull-failure wording is daemon-backend dependent (classic graphdriver: "pull access denied for ..."; containerd image store: "...: not found"), and OutputMatches only checks stdout while the daemon's progress line is written to stderr. Assert the image name appears on stderr instead, which holds regardless of backend or wording. Signed-off-by: Ricardo Branco <[email protected]>
