Integration tests
=================

VSPERF includes a set of integration tests defined in conf/integration.
These tests can be run by specifying --integration as a parameter to vsperf.
Current tests in conf/integration include switch functionality and Overlay
tests.

Tests in the conf/integration can be used to test scaling of different switch
configurations by adding steps into the test case.

For the overlay tests VSPERF supports VXLAN, GRE and GENEVE tunneling protocols.
Testing of these protocols is limited to unidirectional traffic and
P2P (Physical to Physical scenarios).

NOTE: The configuration for overlay tests provided in this guide is for
unidirectional traffic only.

Executing Integration Tests
---------------------------

To execute integration tests VSPERF is run with the integration parameter. To
view the current test list simply execute the following command:

.. code-block:: console

    ./vsperf --integration --list

The standard tests included are defined inside the
``conf/integration/01_testcases.conf`` file.

Test Steps
----------

Execution of integration tests are done on a step by step work flow starting
with step 0 as defined inside the test case. Each step of the test increments
the step number by one which is indicated in the log.

.. code-block:: console

    (testcases.integration) - Step 1 - 'vswitch add_switch ['int_br1']' ... OK

Each step in the test case is validated. If a step does not pass validation the
test will fail and terminate. The test will continue until a failure is detected
or all steps pass. A csv report file is generated after a test completes with an
OK or FAIL result.

Test objects and their functions
--------------------------------

Every test step can call a function of one of the supported test objects. The list
of supported objects and their most common functions follows:

    * ``vswitch`` - provides functions for vSwitch configuration

      List of supported functions:

        * ``add_switch br_name`` - creates a new switch (bridge) with given ``br_name``
        * ``del_switch br_name`` - deletes switch (bridge) with given ``br_name``
        * ``add_phy_port br_name`` - adds a physical port into bridge specified by ``br_name``
        * ``add_vport br_name`` - adds a virtual port into bridge specified by ``br_name``
        * ``del_port br_name port_name`` - removes physical or virtual port specified by
          ``port_name`` from bridge ``br_name``
        * ``add_flow br_name flow`` - adds flow specified by ``flow`` dictionary into
          the bridge ``br_name``; Content of flow dictionary will be passed to the vSwitch.
          In case of Open vSwitch it will be passed to the ``ovs-ofctl add-flow`` command.
          Please see Open vSwitch documentation for the list of supported flow parameters.
        * ``del_flow br_name [flow]`` - deletes flow specified by ``flow`` dictionary from
          bridge ``br_name``; In case that optional parameter ``flow`` is not specified
          or set to an empty dictionary ``{}``, then all flows from bridge ``br_name``
          will be deleted.
        * ``dump_flows br_name`` - dumps all flows from bridge specified by ``br_name``
        * ``enable_stp br_name`` - enables Spanning Tree Protocol for bridge ``br_name``
        * ``disable_stp br_name`` - disables Spanning Tree Protocol for bridge ``br_name``
        * ``enable_rstp br_name`` - enables Rapid Spanning Tree Protocol for bridge ``br_name``
        * ``disable_rstp br_name`` - disables Rapid Spanning Tree Protocol for bridge ``br_name``

            ['tools', 'assert', '#STEP[-1][0]>1']

    * ``wait`` - is used for test case interruption. This object doesn't have
      any functions. Once reached, vsperf will pause test execution and waits
      for press of ``Enter key``. It can be used during testcase design
      for debugging purposes.

      Examples:

      .. code-block:: python

        ['wait']

Test Macros
-----------

Test profiles can include macros as part of the test step. Each step in the
profile may return a value such as a port name. Recall macros use #STEP to
indicate the recalled value inside the return structure. If the method the
test step calls returns a value it can be later recalled, for example:

.. code-block:: python

    {
        "Name": "vswitch_add_del_vport",
        "Deployment": "clean",
        "Description": "vSwitch - add and delete virtual port",
        "TestSteps": [
                ['vswitch', 'add_switch', 'int_br0'],               # STEP 0
                ['vswitch', 'add_vport', 'int_br0'],                # STEP 1
                ['vswitch', 'del_port', 'int_br0', '#STEP[1][0]'],  # STEP 2
                ['vswitch', 'del_switch', 'int_br0'],               # STEP 3
             ]
    }

This test profile uses the vswitch add_vport method which returns a string
value of the port added. This is later called by the del_port method using the
name from step 1.

It is also possible to use negative indexes in step macros. In that case
``#STEP[-1]`` will refer to the result from previous step, ``#STEP[-2]``
will refer to result of step called before previous step, etc. It means,
that you could change ``STEP 2`` from previous example to achieve the same
functionality:

.. code-block:: python

                ['vswitch', 'del_port', 'int_br0', '#STEP[-1][0]'],  # STEP 2

Also commonly used steps can be created as a separate profile.

.. code-block:: python

    STEP_VSWITCH_PVP_INIT = [
        ['vswitch', 'add_switch', 'int_br0'],           # STEP 0
        ['vswitch', 'add_phy_port', 'int_br0'],         # STEP 1
        ['vswitch', 'add_phy_port', 'int_br0'],         # STEP 2
        ['vswitch', 'add_vport', 'int_br0'],            # STEP 3
        ['vswitch', 'add_vport', 'int_br0'],            # STEP 4
    ]

This profile can then be used inside other testcases

.. code-block:: python

    {
        "Name": "vswitch_pvp",
        "Deployment": "clean",
        "Description": "vSwitch - configure switch and one vnf",
        "TestSteps": STEP_VSWITCH_PVP_INIT +
                     [
                        ['vnf', 'start'],
                        ['vnf', 'stop'],
                     ] +
                     STEP_VSWITCH_PVP_FINIT
    }

HelloWorld and other basic Testcases
------------------------------------

The following examples are for demonstration purposes.
You can run them by copying and pasting into the
conf/integration/01_testcases.conf file.
A command-line instruction is shown at the end of each
example.

HelloWorld
^^^^^^^^^^

The first example is a HelloWorld testcase.
It simply creates a bridge with 2 physical ports, then sets up a flow to drop
incoming packets from the port that was instantiated at the STEP #1.
There's no interaction with the traffic generator.
Then the flow, the 2 ports and the bridge are deleted.
'add_phy_port' method creates a 'dpdk' type interface that will manage the
physical port. The string value returned is the port name that will be referred
by 'del_port' later on.

.. code-block:: python

    {
        "Name": "HelloWorld",
        "Description": "My first testcase",
        "Deployment": "clean",
        "TestSteps": [
            ['vswitch', 'add_switch', 'int_br0'],   # STEP 0
            ['vswitch', 'add_phy_port', 'int_br0'], # STEP 1
            ['vswitch', 'add_phy_port', 'int_br0'], # STEP 2
            ['vswitch', 'add_flow', 'int_br0', {'in_port': '#STEP[1][1]', \
                'actions': ['drop'], 'idle_timeout': '0'}],
            ['vswitch', 'del_flow', 'int_br0'],
            ['vswitch', 'del_port', 'int_br0', '#STEP[1][0]'],
            ['vswitch', 'del_port', 'int_br0', '#STEP[2][0]'],
            ['vswitch', 'del_switch', 'int_br0'],
        ]

    }

To run HelloWorld test:

  .. code-block:: console

    ./vsperf --conf-file user_settings.py --integration HelloWorld

Specify a Flow by the IP address
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The next example shows how to explicitly set up a flow by specifying a
destination IP address.
All packets received from the port created at STEP #1 that have a destination
IP address = 90.90.90.90 will be forwarded to the port created at the STEP #2.

.. code-block:: python

    {
        "Name": "p2p_rule_l3da",
        "Description": "Phy2Phy with rule on L3 Dest Addr",
        "Deployment": "clean",
        "biDirectional": "False",
        "TestSteps": [
            ['vswitch', 'add_switch', 'int_br0'],   # STEP 0
            ['vswitch', 'add_phy_port', 'int_br0'], # STEP 1
            ['vswitch', 'add_phy_port', 'int_br0'], # STEP 2
            ['vswitch', 'add_flow', 'int_br0', {'in_port': '#STEP[1][1]', \
                'dl_type': '0x0800', 'nw_dst': '90.90.90.90', \
                'actions': ['output:#STEP[2][1]'], 'idle_timeout': '0'}],
            ['trafficgen', 'send_traffic', {'traffic_type' : 'continuous'}],
            ['vswitch', 'dump_flows', 'int_br0'],   # STEP 5
            ['vswitch', 'del_flow', 'int_br0'],     # STEP 7 == del-flows
            ['vswitch', 'del_port', 'int_br0', '#STEP[1][0]'],
            ['vswitch', 'del_port', 'int_br0', '#STEP[2][0]'],
            ['vswitch', 'del_switch', 'int_br0'],
        ]
    },

To run the test:

  .. code-block:: console

    ./vsperf --conf-file user_settings.py --integration p2p_rule_l3da

Multistream feature
^^^^^^^^^^^^^^^^^^^

The next testcase uses the multistream feature.
The traffic generator will send packets with different UDP ports.
That is accomplished by using "Stream Type" and "MultiStream" keywords.
4 different flows are set to forward all incoming packets.

.. code-block:: python

    {
        "Name": "multistream_l4",
        "Description": "Multistream on UDP ports",
        "Deployment": "clean",
        "Stream Type": "L4",
        "MultiStream": 4,
        "TestSteps": [
            ['vswitch', 'add_switch', 'int_br0'],   # STEP 0
            ['vswitch', 'add_phy_port', 'int_br0'], # STEP 1
            ['vswitch', 'add_phy_port', 'int_br0'], # STEP 2
            # Setup Flows
            ['vswitch', 'add_flow', 'int_br0', {'in_port': '#STEP[1][1]', \
                'dl_type': '0x0800', 'nw_proto': '17', 'udp_dst': '0', \
                'actions': ['output:#STEP[2][1]'], 'idle_timeout': '0'}],
            ['vswitch', 'add_flow', 'int_br0', {'in_port': '#STEP[1][1]', \
                'dl_type': '0x0800', 'nw_proto': '17', 'udp_dst': '1', \
                'actions': ['output:#STEP[2][1]'], 'idle_timeout': '0'}],
            ['vswitch', 'add_flow', 'int_br0', {'in_port': '#STEP[1][1]', \
                'dl_type': '0x0800', 'nw_proto': '17', 'udp_dst': '2', \
                'actions': ['output:#STEP[2][1]'], 'idle_timeout': '0'}],
            ['vswitch', 'add_flow', 'int_br0', {'in_port': '#STEP[1][1]', \
                'dl_type': '0x0800', 'nw_proto': '17', 'udp_dst': '3', \
                'actions': ['output:#STEP[2][1]'], 'idle_timeout': '0'}],
            # Send mono-dir traffic
            ['trafficgen', 'send_traffic', {'traffic_type' : 'continuous', \
                'bidir' : 'False'}],
            # Clean up
            ['vswitch', 'del_flow', 'int_br0'],
            ['vswitch', 'del_port', 'int_br0', '#STEP[1][0]'],
            ['vswitch', 'del_port', 'int_br0', '#STEP[2][0]'],
            ['vswitch', 'del_switch', 'int_br0'],
         ]
    },

To run the test:

  .. code-block:: console

    ./vsperf --conf-file user_settings.py --integration multistream_l4

PVP with a VM Replacement
^^^^^^^^^^^^^^^^^^^^^^^^^

This example launches a 1st VM in a PVP topology, then the VM is replaced
by another VM.
When VNF setup parameter in ./conf/04_vnf.conf is "QemuDpdkVhostUser"
'add_vport' method creates a 'dpdkvhostuser' type port to connect a VM.

VM with a Linux bridge
^^^^^^^^^^^^^^^^^^^^^^

In this example a command-line parameter allows to set up a Linux bridge into
the guest VM.
That's one of the available ways to specify the guest application.
Packets matching the flow will be forwarded to the VM.

Executing Tunnel encapsulation tests
------------------------------------

The VXLAN OVS DPDK encapsulation tests requires IPs, MAC addresses,
bridge names and WHITELIST_NICS for DPDK.

NOTE: Only Ixia traffic generators currently support the execution of the tunnel
encapsulation tests. Support for other traffic generators may come in a future
release.

Default values are already provided. To customize for your environment, override
the following variables in you user_settings.py file:

  .. code-block:: python

    # Variables defined in conf/integration/02_vswitch.conf
    # Tunnel endpoint for Overlay P2P deployment scenario
    # used for br0
    VTEP_IP1 = '192.168.0.1/24'

    # Used as remote_ip in adding OVS tunnel port and
    # to set ARP entry in OVS (e.g. tnl/arp/set br-ext 192.168.240.10 02:00:00:00:00:02
    VTEP_IP2 = '192.168.240.10'

    # Network to use when adding a route for inner frame data
    VTEP_IP2_SUBNET = '192.168.240.0/24'

    # Bridge names
    TUNNEL_INTEGRATION_BRIDGE = 'br0'
    TUNNEL_EXTERNAL_BRIDGE = 'br-ext'

    # IP of br-ext
    TUNNEL_EXTERNAL_BRIDGE_IP = '192.168.240.1/24'

    # vxlan|gre|geneve
    TUNNEL_TYPE = 'vxlan'

    # Variables defined conf/integration/03_traffic.conf
    # For OP2P deployment scenario
    TRAFFICGEN_PORT1_MAC = '02:00:00:00:00:01'
    TRAFFICGEN_PORT2_MAC = '02:00:00:00:00:02'
    TRAFFICGEN_PORT1_IP = '1.1.1.1'

             --test-params 'tunnel_type=geneve' overlay_p2p_decap_cont


Executing Tunnel encapsulation+decapsulation tests
--------------------------------------------------

The OVS DPDK encapsulation_decapsulation tests requires IPs, MAC addresses,
bridge names and WHITELIST_NICS for DPDK.

The test cases can test the tunneling encap and decap without using any ingress
overlay traffic as compared to above test cases. To achieve this the OVS is
configured to perform encap and decap in a series on the same traffic stream as
given below.

TRAFFIC-IN --> [ENCAP] --> [MOD-PKT] --> [DECAP] --> TRAFFIC-OUT


Default values are already provided. To customize for your environment, override
the following variables in you user_settings.py file:

  .. code-block:: python

    # Variables defined in conf/integration/02_vswitch.conf

    # Bridge names
    TUNNEL_EXTERNAL_BRIDGE1 = 'br-phy1'
    TUNNEL_EXTERNAL_BRIDGE2 = 'br-phy2'
    TUNNEL_MODIFY_BRIDGE1 = 'br-mod1'
    TUNNEL_MODIFY_BRIDGE2 = 'br-mod2'

    # IP of br-mod1
    TUNNEL_MODIFY_BRIDGE_IP1 = '10.0.0.1/24'

    # Mac of br-mod1
    TUNNEL_MODIFY_BRIDGE_MAC1 = '00:00:10:00:00:01'

    # IP of br-mod2
    TUNNEL_MODIFY_BRIDGE_IP2 = '20.0.0.1/24'

    #Mac of br-mod2
    TUNNEL_MODIFY_BRIDGE_MAC2 = '00:00:20:00:00:01'

    # vxlan|gre|geneve, Only VXLAN is supported for now.
    TUNNEL_TYPE = 'vxlan'

To run VXLAN encapsulation+decapsulation tests:

  .. code-block:: console

    ./vsperf --conf-file user_settings.py --integration
             overlay_p2p_mod_tput
