Ms. Balen:
Ms. Connell:
Mr. Sarrazin:

Please see the following regarding Interoperability/Regression Testing
requirements.  The LNPA Working Group recommends inclusion of these
guidelines in the Continued Certification Process (CCP).  We will report on
these recommendations at the Cross Regional meeting, April 27, 2000 in
Washington, DC.    Please refer any questions to Shelly Shaw or myself.

Interoperability Testing (ITP)

The LNPA WG recommends that ITP testing be performed on a
SOA/LSMS Developer's software anytime that a change is made to the interface
of either the NPAC SMS or the Developer's SOA/LSMS.  In the event that the
interface change is initiated by the NPAC SMS, the SOA/LSMS Developers shall
perform ITP on each version of SOA/LSMS software that may potentially be
used by Service Providers with the new NPAC SMS interface.

The following provides guidelines for specific scenarios and what level of
testing is recommended for them:

1. When a local product (SOA/LSMS) is compiled with the current interface
model, and a new local feature (SOA/LSMS feature) is implemented that DOES
NOT involve a change in the use of the interface model, and the NPAC
SMS is compiled with the current model, then no ITP testing is required.

2. When a local product is compiled with the current interface model, and no
new local features implemented, and the NPAC SMS is compiled with the new
interface model, then ITP testing is required [appendix E - MOC only].

** this testing verifies the backwards compatibility of the interface **

3. When a local product is compiled with the new interface model, and no new
local features implemented, and the NPAC SMS is compiled with the new
interface model, then ITP testing is required [appendix D - MOC only].

** this testing verifies the backwards compatibility of the interface **

4. When a local product is compiled with the new interface model, and new
local features are implemented that involve the interface, and the NPAC SMS
is compiled with the new interface model, then ITP testing is required
[all appropriate test cases in appendix D and appendix E].

** this testing verifies the new software against the model and the NPAC SMS **

5. When a local product is compiled with the current interface model, and
new local features are implemented that involve the interface, and the NPAC
SMS is compiled with the current model, then ITP testing is
required [verify new feature - appendix E].  Note: the regression test cases would have been
addressed when the vendor upgraded the local product to the current version
of the interface model.
Regression Testing
The LNPA WG recommends that all service providers perform a
minimum set of regression tests for all new releases.
