Subject: [tests] don't fail on network errors
X-Git-Url: https://git.cielonegro.org/gitweb.cgi?a=commitdiff_plain;h=dd508b7c4f0dd8881de07a4e8593d4fcdef9bae7;p=youtube-dl.git

[tests] don't fail on network errors

This is suboptimal, but at least this way we will need to look at the logs
only to check for network errors that happen too often, instead of
parsing a ton of lines each time to see if there is some true test failing
