Summary

This Recommendation provides a graphical presentation format for the test specification and implementation language TTCN-3 (the Testing and Test Control Notation) called GFT. GFT is used for the graphical presentation of test behaviour in form of sequence charts. GFT provides a number of graphical symbols to enable the graphical presentation of TTCN-3 test cases, functions, altsteps and control parts. GFT can be applied whenever it is necessary to define or document test behaviour graphically.
