6 Conformance Testing Methodology
6.1 General
6.1.1 Implementation Under Test Implementation under test (IUT) is an object that is being tested for conformity. For complete implementation of ANSI INCITS 377-2004, it should be a collection of BDIRs containing information from one or more finger patterns, as well as a system or application that implements ANSI INCITS 377-2004 in accordance with its conformance clause.
6.1.2 Claimed Conformance IUT claiming conformance to ANSI INCITS 377-2004 are expected to conform to all the applicable requirements in its conformity clause 2, as well as other requirements set forth in the subsequent clauses of ANSI INCITS 377-2004. These requirements can be:
a) Mandatory requirements – Such requirements are to be observed in all cases.
b) Conditional requirements – Such requirements are to be observed if the conditions set out in the specification apply.
c) Potential requirements – Such requirements can be selected to suit the implementation, and are to be observed if selected.
6.1.3 Evaluation of Conformance To evaluate the conformity of a biometric product, it is necessary to have a statement of the capabilities that have been implemented in conformance with ANSI INCITS 377-2004 so that the implementation can be tested for conformity against relevant requirements and against those requirements only. Such a statement is called an ANSI INCITS 377-2004 Finger Pattern Data Record Conformity Statement (FCS), and shall be prepared by the IUT supplier prior to the beginning of the Conformance Testing. The FCS shall contain the minimum requirements of ANSI INCITS 377-2004 that are included in the IUT.
6.2 Level I and Level II Assertions As described in ANSI INCITS 423.1 -2008, the IUT shall be tested for the conformity specified in ANSI INCITS 377-2004 using two levels of testing. These Conformance Testing Levels are: Level 1 : Data Format Conformance – Such requirements are to be observed for all fields. Level 2: Internal Consistency Checking – Such requirements are to be observed for several fields, as detailed in clause 7. The specific test assertions required for Level 1 and Level 2 conformance testing of ANSI INCITS 377-2004, Finger Pattern Data Interchange Format, are listed in table 1 . Certain computations mentioned in this table are further explained in the notes that follow it.
