ASF GitHub Bot commented on DISPATCH-1901:
------------------------------------------
ChugR opened a new pull request #966:
URL: https://github.com/apache/qpid-dispatch/pull/966
The system_tests_bad_configuration test sets up a connector to a
host that is never reachable. The test expects the connection to fail.
On Linux proton normally returns 'Name or service not known'. On macOS
there is some other specific reason.
Another class of errors shows up when DNS is unavailable. On Linux the
reason is 'Temporary failure in name resolution'.
This patch stops looking for specific text from the proton:io error
messages. The test declares success when a qpid-dispatch log message
indicates a connection failure to the host in question.

> It is unreasonable to expect the test environment to have DNS available just

> so that any proton IO error is accepted.
