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_04_afi_ipv4 (__main__.TestProtocolsBGP) ... ok - test_bgp_05_afi_ipv6 (__main__.TestProtocolsBGP) ... ok - test_bgp_06_listen_range (__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_hash_policy (__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_8021q_lower_up_down (__main__.BondingInterfaceTest) ... ok - test_vif_8021q_mtu_limits (__main__.BondingInterfaceTest) ... ok - test_vif_8021q_qos_change (__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".
