Metode za preskušanje in specificiranje (MTS) - 3. različica zapisa preskušanja in krmilnih preskusov - 1. del: Jedrni jezik TTCN-3
Ta dokument določa jedrni jezik TTCN-3. TTCN-3 je mogoče uporabiti za specificiranje vseh vrst reaktivnih sistemskih preskusov prek različnih komunikacijskih vrat. Običajna področja uporabe so preskušanje protokolov (vključno z mobilnimi in internetnimi protokoli), preskušanje storitev (vključno z dopolnilnimi storitvami), preskušanje modulov, preskušanje platform na osnovi arhitekture CORBA®, programski vmesniki (API) itd. TTCN-3 ni omejen na preskušanje skladnosti in se lahko uporabi za številne druge vrste preskušanja, vključno s preskušanjem medobratovalnosti, robustnosti, regresije, sistema in integracije. Specificiranje preskuševalnih nizov za protokole fizične plasti ne spada na področje uporabe tega dokumenta.
TTCN-3 je namenjen uporabi za specificiranje preskuševalnih nizov, ki so neodvisni od preskusnih metod, plasti in protokolov. Poleg besedilnega formata, ki je opredeljen v tem dokumentu, standard GFT (ETSI ES 201 873-3 [i.2]) določa format grafične predstavitve jezika TTCN-3. Specificiranje teh formatov ne spada na področje uporabe tega dokumenta.
Zasnova jezika TTCN-3 upošteva postopno uvedbo prevajalnikov TTCN-3, vendar pa realizacija izvršljivih preskuševalnih nizov (ETS) iz abstraktnih preskuševalnih nizov (ATS) ne spada na področje uporabe tega dokumenta.
