The test suite only needs a network to download Thunderbird and and the
required Debian packages. There is no network access required for
running any test; in particular, the test suite contains no request to
any keyserver or similar.

You mentioned the following line in the log:
> 2020-02-26 18:05:54.188 [DEBUG] keyRefreshService.jsm: Either no
keyservers exist or the protocols specified are invalid. Will recheck in
an hour.

This has nothing to do with network access from the test suite. The
correct interpretation of such Debug log entries is the following:

The test suite is running so long that the usual key refresh service is
becoming active. However, there is no valid configured keyserver, thus
the service  doesn't do anything. It will retry in an hour to see if
there is a configured keyserver.


I checked the log file, and I believe that the problem is in the
infrastructure. There are error messages from GnuPG that I would expect
under normal circumstances. The first suspicious log entry is this one:
2020-02-26 17:05:06.247

All of a sudden, GnuPG cannot access pubring.kbx anymore, and thus the
test fail. I assume that some test cases don't foresee such errors and
get stuck.
