-
-One of the major advantages introduced in VyOS 1.3 is an autmated test framework.
-When assembling an ISO image multiple things can go wrong badly and publishing
-a faulty ISO makes no sense. The user is disappointed by the quality of the image
-and the developers get flodded with bug reports over and over again.
-
-As the VyOS documentation is not only for users but also for the developers -
-and we keep no secret documentation - this section describes how the automated
-testing works.
-
-Jenkins CI
-==========
-
-Our `VyOS CI`_ system is based on Jenkins and builds all our required packages
-for VyOS 1.2 to 1.4. In addition to the package build, there is the vyos-build
-Job which builds and tests the VyOS ISO image which is published after a
-successfull test drive.
-
-We differentiate in two independent tests, which are both run in parallel by
-two separate QEmu instances which are launched via ``make test`` and ``make
-testc`` from within the vyos-build_ repository.
-
-Smoketests
-==========
-
-Smoketests executes predefined VyOS CLI commands and checks if the desired
-daemon/service configuration is rendert - that is how to put it "short".
-
-When and ISO image is assembled by the `VyOS CI`_, the ``BUILD_SMOKETEST``
-parameter is enabled by default, which will extend the ISO configuration line
-with the following packages:
-
-.. code-block:: python
-
- def CUSTOM_PACKAGES = ''
- if (params.BUILD_SMOKETESTS)
- CUSTOM_PACKAGES = '--custom-package vyos-1x-smoketest'
-
-So if you plan to build your own custom ISO image and wan't to make use of our
-smoketests, ensure that you have the `vyos-1x-smoketest` package installed.
-
-The ``make test`` command from the vyos-build_ repository will launch a new
-QEmu instance and the ISO image is first installed to the virtual harddisk.
-
-After its first boot into the newly installed system the main Smoketest script
-is executed, it can be found here: `/usr/bin/vyos-smoketest`
-
-The script only searches for executable "test-cases" under
-``/usr/libexec/vyos/tests/smoke/cli/`` and executes them one by one.
-
-.. note:: As Smoketests will alter the system configuration and you are logged
- in remote you may loose your connection to the system.
-
-Manual Smoketest Run
---------------------
-
-On the other hand - as each test is contain in its own file - one can always
-execute a single Smoketest by hand by simply running the Python test scripts.
-
-Example:
-
-.. code-block:: none
-
- vyos@vyos:~$ /usr/libexec/vyos/tests/smoke/cli/test_protocols_bgp.py
- test_bgp_01_simple (__main__.TestProtocolsBGP) ... ok
- test_bgp_02_neighbors (__main__.TestProtocolsBGP) ... ok
- test_bgp_03_peer_groups (__main__.TestProtocolsBGP) ... ok

- test_bgp_07_l2vpn_evpn (__main__.TestProtocolsBGP) ... ok
- test_bgp_08_zebra_route_map (__main__.TestProtocolsBGP) ... ok
- test_bgp_09_distance_and_flowspec (__main__.TestProtocolsBGP) ... ok
- test_bgp_10_vrf_simple (__main__.TestProtocolsBGP) ... ok
- test_bgp_11_confederation (__main__.TestProtocolsBGP) ... ok
- test_bgp_12_v6_link_local (__main__.TestProtocolsBGP) ... ok
- test_bgp_13_solo (__main__.TestProtocolsBGP) ... ok
-
- ----------------------------------------------------------------------
- Ran 13 tests in 348.191s
-
- OK
-
-Interface based tests
----------------------
-
-Our smoketests not only test daemons and serives, but also check if what we
-configure for an interface works. Thus there is a common base classed named:
-``base_interfaces_test.py`` which holds all the common code that an interface
-supports and is tested.
-
-Those common tests consists out of:
-
-* Add one or more IP addresses
-* DHCP client and DHCPv6 prefix delegation
-* MTU size
-* IP and IPv6 options
-* Port description
-* Port disable
-* VLANs (QinQ and regular 802.1q)
-* ...
-
-.. note:: When you are working on interface configuration and you also wan't to
- test if the Smoketests pass you would normally loose the remote SSH connection
- to your :abbr:`DUT (Device Under Test)`. To handle this issue, some of the
- interface based tests can be called with an environment variable beforehand
- to limit the number of interfaces used in the test. By default all interface
- e.g. all Ethernet interfaces are used.
-
-.. code-block:: none
-
- vyos@vyos:~$ TEST_ETH="eth1 eth2" /usr/libexec/vyos/tests/smoke/cli/test_interfaces_bonding.py
- test_add_multiple_ip_addresses (__main__.BondingInterfaceTest) ... ok
- test_add_single_ip_address (__main__.BondingInterfaceTest) ... ok

- test_bonding_lacp_rate (__main__.BondingInterfaceTest) ... ok
- test_bonding_min_links (__main__.BondingInterfaceTest) ... ok
- test_bonding_remove_member (__main__.BondingInterfaceTest) ... ok
- test_dhcpv6_client_options (__main__.BondingInterfaceTest) ... ok
- test_dhcpv6pd_auto_sla_id (__main__.BondingInterfaceTest) ... ok
- test_dhcpv6pd_manual_sla_id (__main__.BondingInterfaceTest) ... ok
- test_interface_description (__main__.BondingInterfaceTest) ... ok
- test_interface_disable (__main__.BondingInterfaceTest) ... ok
- test_interface_ip_options (__main__.BondingInterfaceTest) ... ok
- test_interface_ipv6_options (__main__.BondingInterfaceTest) ... ok
- test_interface_mtu (__main__.BondingInterfaceTest) ... ok
- test_ipv6_link_local_address (__main__.BondingInterfaceTest) ... ok
- test_mtu_1200_no_ipv6_interface (__main__.BondingInterfaceTest) ... ok
- test_span_mirror (__main__.BondingInterfaceTest) ... ok
- test_vif_8021q_interfaces (__main__.BondingInterfaceTest) ... ok

- test_vif_s_8021ad_vlan_interfaces (__main__.BondingInterfaceTest) ... ok
- test_vif_s_protocol_change (__main__.BondingInterfaceTest) ... ok
-
- ----------------------------------------------------------------------
- Ran 23 tests in 244.694s
-
- OK
-
-This will limit the `bond` interface test to only make use of `eth1` and `eth2`
-as member ports.
-
-Config Load Tests
-=================
-
-The other part of our tests are called "config load tests". The config load tests
-will load - one after another - arbitrary configuration files to test if the
-configuration migration scripts work as designed and that a given set of
-functionality still can be loaded with a fresh VyOS ISO image.
-
-The configurations are all derived from production systems and can not only act
-as a testcase but also as reference if one wants to enable a certain feature.
-The configurations can be found here:
-https://github.com/vyos/vyos-1x/tree/current/smoketest/configs
-
-The entire test is controlled by the main wrapper script ``/usr/bin/vyos-configtest``
-which behaves in the same way as the main smoketest script. It scans the folder
-for potential configuration files and issues a ``load`` command one after another.
-
-Manual config load test
------------------------
-
-One is not bound to load all configurations one after another but can also load
-individual test configurations on his own.
-
-.. code-block:: none
-
- vyos@vyos:~$ configure

- Those most likely include generation of crypographic keys before the config
- can be applied - you will get a commit error otherwise. If you are interested
- how those preconditions are fulfilled check the vyos-build_ repository and
- the ``scripts/check-qemu-install`` file.
