-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``

-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

- ]
-
- }
-
-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.

-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.

+Step driven tests
+=================
+
+In general, test scenarios are defined by a ``deployment`` used in the particular
+test case definition. The chosen deployment scenario will take care of the vSwitch
+configuration, deployment of VNFs and it can also affect configuration of a traffic
+generator. In order to allow a more flexible way of testcase scripting, VSPERF supports
+a detailed step driven testcase definition. It can be used to configure and
+program vSwitch, deploy and terminate VNFs, execute a traffic generator,
+modify a VSPERF configuration, execute external commands, etc.
+
+Execution of step driven tests is 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 0 'vswitch add_vport ['br0']' start
+
+Step driven tests can be used for both performance and integration testing.
+In case of integration test, 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.
+
+In case of performance test, the validation of steps is not performed and
+standard output files with results from traffic generator and underlying OS
+details are generated by vsperf.
+
+Step driven testcases can be used in two different ways:
+
+ # description of full testcase - in this case ``clean`` deployment is used
+ to indicate that vsperf should neither configure vSwitch nor deploy any VNF.
+ Test shall perform all required vSwitch configuration and programming and
+ deploy required number of VNFs.
+
+ # modification of existing deployment - in this case, any of supported
+ deployments can be used to perform initial vSwitch configuration and
+ deployment of VNFs. Additional actions defined by TestSteps can be used
+ to alter vSwitch configuration or deploy additional VNFs. After the last
+ step is processed, the test execution will continue with traffic execution.
+
+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``

+ 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

+ ['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

+
+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.

+
+This example launches a 1st VM in a PVP topology, then the VM is replaced

+Overriding values defined in configuration files
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The configuration items can be overridden by command line argument
+``--test-params``. In this case, the configuration items and
+their values should be passed in form of ``item=value`` and separated
+by semicolon.
+
+Example:
+
+.. code:: console
+
+ $ ./vsperf --test-params "TRAFFICGEN_DURATION=10;TRAFFICGEN_PKT_SIZES=(128,);" \
+ "GUEST_LOOPBACK=['testpmd','l2fwd']" pvvp_tput
+
+The second option is to override configuration items by ``Parameters`` section
+of the test case definition. The configuration items can be added into ``Parameters``
+dictionary with their new values. These values will override values defined in
+configuration files or specified by ``--test-params`` command line argument.
+
+Example:
+
+.. code:: python
+
+ "Parameters" : {'TRAFFICGEN_PKT_SIZES' : (128,),
+ 'TRAFFICGEN_DURATION' : 10,
+ 'GUEST_LOOPBACK' : ['testpmd','l2fwd'],
+ }
+
+**NOTE:** In both cases, configuration item names and their values must be specified
+in the same form as they are defined inside configuration files. Parameter names
+must be specified in uppercase and data types of original and new value must match.
+Python syntax rules related to data types and structures must be followed.
+For example, parameter ``TRAFFICGEN_PKT_SIZES`` above is defined as a tuple
+with a single value ``128``. In this case trailing comma is mandatory, otherwise
+value can be wrongly interpreted as a number instead of a tuple and vsperf
+execution would fail. Please check configuration files for default values and their
+types and use them as a basis for any customized values. In case of any doubt, please
+check official python documentation related to data structures like tuples, lists
+and dictionaries.
+
+**NOTE:** Vsperf execution will terminate with runtime error in case, that unknown
+parameter name is passed via ``--test-params`` CLI argument or defined in ``Parameters``
+section of test case definition. It is also forbidden to redefine a value of
+``TEST_PARAMS`` configuration item via CLI or ``Parameters`` section.
