Metode za preskušanje in specificiranje (MTS) - 3. različica zapisa preskušanja in krmiljenja preskusov - 5. del: Vmesnik za čas izvajanja (TRI) TTCN-3

Ta dokument določa specificiranje vmesnika za čas izvajanja za preskusne izvedbe sistema TTCN-3. Vmesnik za čas izvajanja TTCN-3 zagotavlja standardizirano prilagoditev za časovni razpored in komunikacijo preskusnega sistema v povezavi z določeno obdelovalno platformo ter sistemom za preskušanje. V tem dokumentu je vmesnik opredeljen kot niz postopkov, neodvisnih od ciljnega jezika. Vmesnik je opredeljen kot združljiv s standardom TTCN-3 (glej ETSI ES 201 873-1 [2]). Za popolno določitev TRI je v tem dokumentu uporabljen jezik za definicijo vmesnikov (IDL) CORBA. V točkah 6, 7 in 8 so predstavljene jezikovne preslikave za to abstraktno specificiranje v ciljne jezike Java™, ANSI C in C++. Povzetek specifikacij vmesnikov na osnovi jezika IDL je podan v dodatku A.
OPOMBA: Java™ je tržno ime programskega jezika, ki ga je razvila družba Oracle Corporation. Te informacije so navedene za boljše razumevanje standarda s strani uporabnikov in ne pomenijo, da ETSI podpira imenovani programski jezik. Uporabljajo se lahko enakovredni programski jeziki, ki zagotavljajo enake rezultate.
