31 Testing and Certification Slide 32 Why We Need Certification
Testing and Certification affords implementers confidence that they
will likely interoperate with other independently developed
implementations Minimum agreed performance threshold gives
interoperability value and therefore increases the value of the
brand Dispersion of implementations costs implementers Exception
handling code quickly exceeds implementation code Differences risk
functionality apps depend on Dispersion of implementations costs
Data Custodians Need to deal with Third Parties with different
needs and expectations Unwanted support calls from consumers about
difficulties with their apps due to inconsistent implementation 32
Slide 33 Conformance Testing vs. Certification Conformance testing
evaluates all implemented features of the standard including
implementation agreements Certification testing evaluates a subset
of conformance tests based on one or more specific profiles using
protocol implementation conformance statements (PICs) 33 Slide 34
ITCA) Interoperability Testing and Certification Authority (ITCA)
UCA International Users Group (UCAIug) is seeking Accreditation
Bodies (AB), Certification Bodies (CB), and Conformity and
Interoperability Test Laboratories (TL) to participate in
implementing UCAIugs Green Button product certification program.
This program will include: Design and implementation of one or more
UCAIug certification test programs based on the ESPI NAESB REQ.21
Standard and the UCAIug Quality Assurance Program (see Section 1.3
for reference) Collaboration with the UCAIug certification test
tool partner to smoothly implement the certification test tools and
promptly report any errors found during the process Advise UCAIug
on program implementation 34 Slide 35 How Testing And Certification
Is to be Accomplished OpenADE Task Force develops requirements and
implementation agreements for ESPI and produces a test plan that
encompasses Green Button Download My Data Green Button Connect My
