While continuing development of the “Test Description
Language” (TDL), the Technical Committee “Methods for Testing
and Specification” (TC-MTS) at ETSI is focused on bridging
the gap between high level test purposes and test cases. The
process of stepwise development of tests from requirement
specifications is well established and used in both,
standardization and industry. This process is supported by
methods and languages, such as TTCN-3 and TDL. TDL bridges
the gap between declarative test purpose specifications and
imperative test case specifications. The lack of a
standardized mapping of TDL to TTCN-3 may result in a
proliferation of different and possibly incompatible tool-
and user-specific mappings of TDL test descriptions to
executable test cases. Facing these challenges and common
problems of bridging the gaps between languages and
representations, users and tool vendors aiming to do the same
with other technologies may benefit. This presentation will
showcase experiences and the currently ongoing work on the
standardized mapping of TDL to TTCN-3.
