Petr Štetiar 77046c9b10 ci: cdrouter: fix hostname resolutions by flushing DNS relay cache We're unable to run CDRouter test for CPE's TR-069 functionality due to the following error during the test init phase: FAIL: Did not receive TR-069 Inform RPC from CPE after 120 seconds » no-wan-tr069-inform Analyzing the logs, issue arise whenever CPE manages to get a first WAN address from testbed server instead of CDRouter. With additional unbound traces we can see what happens: As WAN is up, DNS query for controller.cdroutertest.com is forwarded to configured upstream DSN server (8.8.8.8 and 1.1.1.1) 1.1.1.1 will reply with a SOA as cdroutertest.com is registered: cdroutertest.com. 3600 IN SOA ns1.linode.com. support.qacafe.com. 2021000016 14400 14400 1209600 86400 As TTLS is set to 3600 seconds, unbound will cache this as a negative answer for 1 hour. Latter upstream of CPE is switched to CDRouter, obuspa tries to resolve controller.cdroutertest.com, but it gets the cached answer as its TTL is not expired, and no WAN DSN query is done. So lets fix it by flushing the DNS relay cache during the DUT init phase, once the network is switched to the CDRouter.

Content

This directory contains files used mainly during testing on the GitLab CI.

requirements.txt

This requirements.txt file is used for specifying what Python packages are required to run the scripts in this directory. Usually used with pip install -f requirements.txt command.

prpl-jira.py

This helper Python script creates new or updates existing Jira ticket when something goes wrong during GitLab CI testing process. Currently only supports reporting of build test failures.

Needs Python version 3.6+ due to use of f-strings feature.

testbed-device.py

This helper Python scripts allows managing of device under test (DUT) via labgrid framework.
