Terminal Test Tool

 

Link 16 interoperability is not limited to confirming that data processing and exchange is occurring correctly.  The terminals that control the provision of the waveforms carrying Link 16 data are themselves complex processors and, as they are themselves subject to through-life development, they need to be tested as a necessary part of system verification and validation.

 

Our Terminal Test Tool (TTT) provides a highly intuitive, process driven application, which reduces cost, increases efficiency, and improves the quality of testing.  Based around IBM DOORS, it provides a rich visual environment that takes the tester from selection of requirements to test, through test development, test execution and results reporting.  It incorporates a central repository for all test inputs and outputs.

 

We use our IBM DOORS expertise to capture all related specification documents and use embedded DOORS traceability links to relate functionality between the various specification documents. A DOORS architectural schema has been designed to support the information model for testing of Tactical Data Link (TDL) hardware.
 
TTT User functionality has been implemented within DOORS through the production of supporting DOORS eXecutable Language (DXL).  This provides access to a range of functionality to manage the selection of requirements and creation of new formal test modules with appropriate automated traceability linkages to the source standards.  The TTT's test tracking tool kit is utilised to elicit results captured against the generated test module.
 
Test reporting is handled through IBM Rational Publishing Engine. A number of report templates are pre-defined supporting the DOORS database schema to output test documentations in an efficient manner.  Test Report, Test Matrix and Verification Cross Reference Index (VCRI) are examples.
