Code Issues Proposed changes

Amend documentation for fullstack tests

Browse Source 
When trying to execute the fullstack tests, I was a little bit lost in
the documentation.
This change is a proposal to refactor this a little bit so the only
source of truth is the doc/source/contributor/testing/fullstack.rst
file.

Fullstack Tests Fullstack Tests
~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~
To run all the fullstack tests, you may use: :: See :ref:`FullStack Testing<fullstack_testing>` guide.
tox -e dsvm-fullstack
Since fullstack tests often require the same resources and
dependencies as the functional tests, using the configuration script
tools/configure_for_func_testing.sh is advised (as described above).
Before running the script, you must first set the following environment
variable so things are setup correctly ::
export VENV=dsvm-fullstack
When running fullstack tests on a clean VM for the first time, it is
important to make sure all of Neutron's package dependencies have been met.
As mentioned in the functional test section above, this can be done by
running the configure script with the '-i' argument ::
./tools/configure_for_func_testing.sh ../devstack -i
You can also run './stack.sh', and if successful, it will have also
verified the package dependencies have been met.
When running on a new VM it is suggested to set the following environment
variable as well, to make sure that all requirements (including database and
message bus) are installed and set ::
export IS_GATE=False
Fullstack-based Neutron daemons produce logs to a sub-folder in the
$OS_LOG_PATH directory (default: /opt/stack/logs, note: if running fullstack
tests on a newly created VM, make sure that $OS_LOG_PATH exists with the
correct permissions) called 'dsvm-fullstack-logs'.
For example, a test named "test_example" will produce logs in
$OS_LOG_PATH/dsvm-fullstack-logs/test_example/, as well as create
$OS_LOG_PATH/dsvm-fullstack-logs/test_example.txt, so that is a good place
to look if your test is failing.
The fullstack test suite assumes 240.0.0.0/4 (Class E) range in the root
namespace of the test machine is available for its usage.
Fullstack tests execute a custom dhclient-script. From kernel version 4.14 onward,
apparmor on certain distros could deny the execution of this script. To be sure,
check journalctl ::
sudo journalctl | grep DENIED | grep fullstack-dhclient-script
To execute these tests, the easiest workaround is to disable apparmor ::
sudo systemctl stop apparmor
sudo systemctl disable apparmor
A more granular solution could be to disable apparmor only for dhclient ::
sudo ln -s /etc/apparmor.d/sbin.dhclient /etc/apparmor.d/disable/

take a pretty long time so lets try to run just one:
