A proposal for graphical extension of TTCN-3 Graphical presentation Format (GFT)

TTCN-3 Graphical presentation Format (GFT), even though it covers several aspects of test suite specification like behavior, structure and configuration of test cases; it does not cover data aspects like definition of types and their usage within test cases (template declaration). As a consequence, TTCN-3 GFT cannot be used as a standalone test suite development format - as it depends on the textual presentation based TTCN-3 core language (CL) for data aspects. Thus, making the graphical presentation capability of TTCN-3 semi graphical. To overcome this inhibition, this paper proposes a graphical extension to TTCN-3 GFT.
