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``
+

+
+ * ``trafficgen`` - triggers traffic generation
+
+ List of supported functions:
+
+ * ``send_traffic traffic`` - starts a traffic based on the vsperf configuration
+ and given ``traffic`` dictionary. More details about ``traffic`` dictionary
+ and its possible values are available at `Traffic Generator Integration Guide
+ <http://artifacts.opnfv.org/vswitchperf/docs/design/trafficgen_integration_guide.html#step-5-supported-traffic-types>`__
+
+ Examples:
+
+ .. code-block:: python
+
+ ['trafficgen', 'send_traffic', {'traffic_type' : 'throughput'}]
+
+ ['trafficgen', 'send_traffic', {'traffic_type' : 'back2back', 'bidir' : 'True'}]
+
+ * ``settings`` - reads or modifies VSPERF configuration
+
+ List of supported functions:
+
+ * ``getValue param`` - returns value of given ``param``
+ * ``setValue param value`` - sets value of ``param`` to given ``value``
+
+ Examples:
+
+ .. code-block:: python
+
+ ['settings', 'getValue', 'TOOLS']
+
+ ['settings', 'setValue', 'GUEST_USERNAME', ['root']]
+
+ * ``namespace`` - creates or modifies network namespaces
+
+ List of supported functions:
+
+ * ``create_namespace name`` - creates new namespace with given ``name``
+ * ``delete_namespace name`` - deletes namespace specified by its ``name``
+ * ``assign_port_to_namespace port name [port_up]`` - assigns NIC specified by ``port``
+ into given namespace ``name``; If optional parameter ``port_up`` is set to ``True``,

+
+ ['veth', 'bring_up_eth_port', 'eth1']
+

+ in case that condition is not ``True``
+ * ``Eval expression`` - evaluates given expression as a python code and returns
+ its result
+ * ``Exec command [regex]`` - executes a shell command and filters its output by
+ (optional) regular expression
+
+ Examples:
+
+ .. code-block:: python
+
+ ['tools', 'exec', 'numactl -H', 'available: ([0-9]+)']
+ ['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
-----------
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.

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.

+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'
