A built-in. User-defined arbiters are realized by the MTC.
Test case with behavior functions. The MTC creates and
starts test components.
Various TTCN-3 messages.
Pre-defined verdicts pass, fail, inconclusive and error. For
user-defined verdicts, a special verdict type is needed.
Test configuration Configuration operations.
Wildcards Data matching mechanisms.
Coding rules Encode attributes.
Timer Timer and timer operations.
Timezone Cannot be mapped.
Fig. 17.4. U2TP to TTCN-3 Mapping Rules
component (MTC). The test context is mapped to the TTCN-3 module definition
part. U2TP test case can be mapped to test cases and functions where
the MTC firstly creates test components and start their behavior by functions.
Stimuli, observation and coordinations are realized by various kinds of messages.
Verdicts are mapped to TTCN-3 verdict types with the predefined verdicts pass,
fail, inconclusive and error. Test configuration are realized by configuration operations.
Wildcards can be mapped to wildcards. Coding rules are realized by
encoding attributes. Timers and timer operations are present for U2TP as well
as for TTCN-3. Timezones are not TTCN-3 concepts. 3
3 Timezones are introduced in another approach of TTCN-3, called TimedTTCN
[DGN02]. The change request has already been submitted to ETSI (European
Telecommunication Standardization Institution) where TTCN-3 has been developed.
