This page is intended as a working draft of how we will look to leverage and develop test cases for the dovetail project.

The dovetail test suite

The dovetail test suite is intended to provide a method for validating the interfaces and behaviors of an NFVi platform according to the expected capabilities exposed in an OPNFV NVFi realization. All dovetail tests will be available in open source and will be developed on readily available open source test frameworks.

Working with the ETSI NFV TST 001reference: http://www.etsi.org/deliver/etsi_gs/NFV-TST/001_099/001/01.01.01_60/gs_NFV-TST001v010101p.pdf
Where I would see our dovetail project focus on SUT tests validating a SUT scope associated with Chapter 4.9 - NFV Infrastructure + VIM Under Test.  While we may also look at interesting use cases like SFC, I would suggest we have clear plan on pre-deployment validation to ensure that any platform we are evaluating is first evaluated to be in a steady state of readiness.

Aside from the very basic requirements we would have on a test case to be used in dovetail:

  • Test cases should implement a published standard interface for validation
    • Where no standard is available provide API support references
    • If a standard exists is not followed an exemption method needs to be established
  • Test cases be documented
    • Use case specification
    • Test preconditions
    • Basic test flow execution descriptor
    • Post conditions and pass fail criteria
    • Parameter border test cases descriptions
    • Fault/Error test case descriptions  (this feels optional at this time)
  • Test documentation/implementation file and directory structure (per supported framework)
  • Test result storage, structure and test result information management (these should be able to be run publically or privately)

 

Phasing the dovetail development effort

While not all tests will be possible to develop at once the following approach is proposed for the development of dovetail test suites in a structured manner.

Dovetail phase 1

Dovetail should initially set out to provide validation of interfaces and behaviors common to an OPNFV NVFi.  This can be seen as a set of test cases that evaluate if a NVFi implementation is able to achieve a steady operational state covering the common behaviors expected of an OPNFV NFVi.  In this case the dovetail tests will focus on a SUT definition of VNFi & VIM as described in 4.9 of the ETSI NFV TST 001 specification.

Dovetail phase 2

Dovetail should further establish a set of test suites that validate additional desired OPNFV VNFi behaviours.  This may include for instance, deployment specific capabilities for edge or remote installations.  It may include the validation of functionality that is not yet common to all OPNFV VNFi scenario's.

In phase 2 it may also be possible that dovetail provides such services as application test suites to validate the behavior of applications in preparation for deployment on an OPNFV VNFi.  This may result in the definition of new SUT scopes for dovetail as described in of the ETSI NFV TST 001 specification.

Dovetail phase 3
