[python-engineio] test failures on F33 koji

[Mukundan Ragavan]

I am trying to fix FTBFS and upgrade engineio to 3.13 (current version
in rawhide is 3.11). Some tests keep failing on koji [0] but not when I
build locally using mock. This is what I see in build log -

_ ERROR collecting tests/common/test_async_eventlet.py _____________
/usr/lib/python3.9/site-packages/dns/resolver.py:743: in read_resolv_conf
    f = stack.enter_context(open(f))
E   FileNotFoundError: [Errno 2] No such file or directory:
'/etc/resolv.conf'
During handling of the above exception, another exception occurred:

<snip>


E   dns.resolver.NoResolverConfiguration: Resolver configuration could
not be read or specified no nameservers.


Pointers to fix this will be greatly appreciated. Thanks!
