This document describes tests that verify on-board unit (OBU) conformance of implementations of functions and data structures, as defined in the implementation conformance statement based on ISO 14906 for electronic fee collection (EFC) applications. It defines tests for assessment of OBU conformance in terms of : – basic dedicated short-range communication (DSRC) L7 functionality, – EFC application functions, – EFC attributes (i.e. EFC application information), – the addressing procedures of EFC attributes and (hardware) components, – the EFC transaction model, which defines the common elements and steps of any EFC transaction, and – the behaviour of the interface so as to support interoperability on an EFC-DSRC application interface level. After the tests of isolated data items and functions (C.2 to C.4), an example is given for testing of a complete EFC transaction (C.3). Whereas this document defines examples of test cases for DSRC and EFC functionality in Annex C, it does not intend to specify a complete test suite for a certain implementation. To compose a test suite for a specific EFC implementation, the test cases may have to be modified and new test cases may have to be defined and added for the conformance test suite to be complete. It can be useful to consider the following when defining a complete test suite: – small range: “exhaustive testing” of critical interoperability/compatibility features, – large range: testing of boundaries and random values, and – composite types: testing of individual items in sequence or parallel.
