Topotests
=========
Topotests is a suite of topology tests for FRR built on top of Mininet.
Topotests is a suite of topology tests for FRR built on top of micronet.
Installation and Setup
----------------------
Only tested with Ubuntu 16.04 and Ubuntu 18.04 (which uses Mininet 2.2.x).
Topotests run under python3. Additionally, for ExaBGP (which is used in some of
the BGP tests) an older python2 version must be installed.
Tested with Ubuntu 20.04 and Ubuntu 18.04 and Debian 11.
Instructions are the same for all setups (i.e. ExaBGP is only used for BGP
tests).

disabled in ``pytest.ini`` file). Pytest will execute up to N tests in parallel
where N is based on the number of cores on the host.
Analyze Test Results (``analyze.py``)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
By default router and execution logs are saved in ``/tmp/topotests`` and an XML
results file is saved in ``/tmp/topotests.xml``. An analysis tool ``analyze.py``
is provided to archive and analyze these results after the run completes.
After the test run completes one should pick an archive directory to store the
results in and pass this value to ``analyze.py``. On first execution the results
are copied to that directory from ``/tmp``, and subsequent runs use that
directory for analyzing the results. Below is an example of this which also
shows the default behavior which is to display all failed and errored tests in
the run.
.. code:: shell
~/frr/tests/topotests# ./analyze.py -Ar run-save

bgp_multiview_topo1/test_bgp_multiview_topo1.py::test_bgp_routingTable
Here we see that 4 tests have failed. We an dig deeper by displaying the
captured logs and errors. First let's redisplay the results enumerated by adding
the ``-E`` flag
.. code:: shell

3 bgp_multiview_topo1/test_bgp_multiview_topo1.py::test_bgp_routingTable
Now to look at the error message for a failed test we use ``-T N`` where N is
the number of the test we are interested in along with ``--errmsg`` option.
.. code:: shell

- Avoid including unstable data in your test: don't rely on link-local
addresses or ifindex values, for example, because these can change
from run to run.
- Using sleep is almost never appropriate to wait for some convergence
event as the sole item done. As an example: if the test resets the peers
in BGP, the test should look for the peers reconverging instead of just
sleeping an arbitrary amount of time and continuing on. It is ok to
use sleep in a tight loop with appropriate show commands to ensure that
the protocol reaches the desired state. This should be bounded by
appropriate timeouts for the protocol in question though. See
verify_bgp_convergence as a good example of this. If you are having
troubles figuring out what to look for, please do not be afraid to ask.
