+**VNF Onboard and Instantiate Test Specification**
+==================================================
+
+.. contents::
+ :local:
+
+Scope
+-----
+
+This specification defines the logical steps and activities required
+to implement a test case that validates that a arbitrary
+Virtual Network Function (VNF) that is packaged in compliance with the
+ONAP VNF Requirements can be successfully be onboarded into
+ONAP and instantiated. This specification only covers up to
+instantiation of the VNF and does not address the VNF's compliance with
+requirements governing other lifecycle functions controlled by
+ONAP (ex: Lifecycle Management, Monitoring, etc.)
+
+Two test cases will be defined based on the VNF package used:
+
+1. ZIP file containing ONAP-compliant OpenStack Heat
+2. Cloud Service Archive (CSAR) containing a Topology and Orchestration
+ Specification for Cloud Applications (TOSCA) VNF Descriptor

+
+Actors
+------
+
+The following defines the various actors that will be referenced within this
+specification. It is expected and permissable that a given user or entity
+can serve in multiple roles for the purposes of the test.
+
+* **VNF Provider** - Responsible for developing, packaging, and distributing a
+ VNF that is compliant with ONAP VNF Requirements as well as providing any
+ additional artifacts required to setup the **Test Lab** or **Test Engine**.
+* **Test Lab** - Hosts the ONAP and Cloud environment used to execute the test
+ cases. The environment will host a deployed instance of ONAP using the
+ official El Alto release of ONAP and a compatible OpenStack cloud instance.
+* **Test Lab Provider** - Responsible for establishing the **Test Lab** and
+ supporting the **Tester** in the configuration of the **Test Lab** for any
+ VNF specific requirements such as virtual machine images or networks. This
+ will include providing the **Test Engine** access to the necessary
+ ONAP APIs/GUIs as well as access to the OpenStack APIs.
+* **Tester** - Responsible for:
+
+ 1. Ensuring the test lab is configured per the VNF's requirements and needs.
+ 2. Configuring the **Test Engine** for execution. The artifacts required
+ will be provided by the **VNF Provider**.
+ 3. Executing the the test cases using the **Test Engine**.
+ 4. Reporting the results of the test case to the **VNF Provider**.
+
+* **Test Engine** - Provides automation of the test execution and verification
+ of the success or failure of the individual test cases. The **Test Engine**
+ must also provide further documentation on how it and the **Test Lab**
+ must be configured for successful execution and verification of the test
+ cases.
+
+
+**Test Case Description**: VNF Onboarding and Instantiation using OpenStack Heat
+--------------------------------------------------------------------------------
+
+This test case is specific to executing and validating the onboarding of a VNF
+using OpenStack Heat.
+
+Assumptions
+^^^^^^^^^^^
+
+* The specific configuration of the Vendor License Model is not relevant to the
+ successful execution of this test case. The **Test Engine** shall create a
+ generic Vendor License Model to assign to the VNF for the purposes of this
+ test.
+* Testing will support the instantiation of a SDC Service that is composed
+ of a single VNF. The scope of this test is focused on the instantiation
+ of a single VNF defined in a single Heat package. Testing services that
+ comprise multiple VNFs is beyond the scope of this specification.
+* The **Test Engine** will have access to the ONAP APIs in terms of both
+ network connectivity and API access.
+* All instantiations will use the ONAP Generic Resource API from SDNC instead
+ of the legacy VNF API.
+
+
+Prerequisites
+^^^^^^^^^^^^^
+
+* **VNF Provider** has:
+
+ * Provided the **Tester** the VNF package containing OpenStack Heat that has
+ been certified compliant by the OPNFV Verification Program for
+ VNFs or validated by the El Alto release of the
+ :doc:`ONAP VNF Validation Platform </../../../../vvp/documentation.git/docs/index>`
+ * Provided the **Tester** any custom virtual machine image required by the
+ VNF
+ * Provided the **Tester** network requirements for any ONAP external networks
+ (i.e. networks not created in the Heat template itself) required by the
+ VNF.
+ * Provided the **Tester** with any additional artifacts required by the
+ **Test Engine**. Additional artifacts required by the **Test Engine** are
+ outside the scope of this document. Please refer to the **Test Engine**
+ documentation for more details.
+
+* **Test Lab Provider** has:
+
+ * Successfully deployed an OpenStack cloud instance for ONAP to deploy and
+ instantiate the VNF.
+ * Successfully deployed the certified El Alto release version of ONAP.
+ * Configured the ONAP instance to work with the OpenStack instance.
+
+ * **NOTE:** Documentation of OpenStack and ONAP setup are beyond the
+ scope of this document. Please refer to the
+ :ref:`vnfrqts_tc_instantiate_references` section for more information.
+
+ * Provided the **Test Engine** network connectivity to both the ONAP and
+ OpenStack control planes.
+ * Provided the **Test Engine** permissions to invoke the required ONAP and
+ OpenStack APIs. Full details to be provided in the **Test Engine**
+ documentation.
+
+* The **Tester** has:
+
+ * Created any external networks in ONAP and OpenStack cloud environment in
+ compliance with the **VNF Providers** request and specification.
+ * Registered any custom virtual machine images provided by the
+ **VNF Provider** in the OpenStack Glance repository.
+ * Configured the **Test Engine** with the necessary artifacts from the
+ **VNF Provider** for successful test execution. The **Test Engine**
+ must provide the full documentation on what is required to configure
+ it for successful execution.
+ * Ensured connectivity from the **Test Engine** to any Operations,
+ Administration, and Management (OAM) interfaces provided by the VNF.
+ This connectivity must allow PING requests which will be used as part
+ of the validation process to ensure the VNF has been properly
+ instantiated.
+
+
+Execution Steps
+^^^^^^^^^^^^^^^
+
+The following steps will all be executed by the **Test Engine**. The steps
+depicts the actions that will be taken and which ONAP component the
+**Test Engine** will interact with to perform the action.
+
+Failure encountered at any step will halt all subsequent steps and result in
+the overall failure of the test case.
+
+Any additional required fields that must be assigned or input within ONAP will
+be defined in a configuration file whose format will be defined in the
+documentation of the **Test Engine**.
+
+**Steps**
+
+1. Create the generic Vendor License Model (VLM) in SDC
+
+2. Create the Vendor Software Product (VSP) in SDC. The VSP will be
+ auto-assigned a unique name to avoid collisions with other VSPs in the
+ lab environment.
+
+3. Upload the ONAP-compliant Heat archive (zip file) as an artifact of the VSP in SDC.
+
+4. Assign any "Unassigned Files" in SDC to Artifacts
+
+5. Validate the VSP and ensure no SDC **errors** are raised, but **warnings**
+ are acceptable. If errors are reported, then halt the test and report a
+ failure.
+
+6. Assign the generic VLM to the VSP in SDC.
+
+7. Create the Virtual Function (VF) in SD. The VF will be
+ auto-assigned a unique name to avoid collisions with other VSPs in the
+ lab environment.
+
+8. Create the Service in SDC. The Service will be
+ auto-assigned a unique name to avoid collisions with other VSPs in the
+ lab environment.
+
+9. Assign the VF/VNF to the Service Model in SDC.
+
+10. Distribute the Service Model from SDC.
+
+11. Register Preload (i.e. per instance configuration data) with SDNC
+
+12. For each VF module in the VNF, starting with the base module, trigger
+ instantiation from VID.
+
+**Pass/Fail Criteria**
+
+Following, or during, test execution the tests below will be executed to
+evaluate the success of the overall test case. As previously stated above, if
+any individual test step fails, then the test case will fail. In this scenario,
+some or all of the criteria below may not be executed.
+
+1. The Heat stack has been successfully created in OpenStack without errors
+2. If the VNF exposes Operations, Administration, and Management (OAM)
+ interfaces on an OAM network, then each IP address address exposed by the
+ VNF on the OAM network must respond to a PING command. The identification
+ of the OAM network and IPs is left to the implementation and documentation
+ of the **Test Engine**.
+3. Each virtual machine in the OpenStack Heat stack must have a corresponding
+ ``vserver`` ONAP's Available and Active Inventory (AAI) component with all
+ required data elements
+4. The VNF has a ``VNFC`` object recorded in AAI with all required data elements
+
+
+**Test Case Description**: VNF Onboarding and Instantiation using TOSCA
+-----------------------------------------------------------------------
+
+This test case is specific to executing and validating the onboarding of a VNF
+written in TOSCA and packaged in a CSAR.
+
+.. note::
+
+ Additional definition of the TOSCA-based flow is required, and will be
+ provided at a later date. \ No newline at end of file
