Test suite error in webfakes
Hi Gábor,
I intend to package webfakes for Debian to enable a full test suite in
some of our packages. Unfortunately the webfakes test suite itself
has some issue when running it inside a restricted environment (with
no internet access and no graphical interface) as it is done as default
in CI in Debian. There is a full test log[1] which shows in line 745:
══ Failed tests ════════════════════════════════════════════════════════════════

Error: Test failures
Execution halted
If you confirm that the failures are due to a lack of internet
connection it would be great if you could make these optional.
Alternatively it is possible to declare that this package needs internet
access to run the full test suite in case you consider it not sensible
to do those tests optional.
Kind regards
Andreas.
