Because distributed system had features of physical distribution

simultaneo us access

being sensitive to sequence and platform isomerism

distributed test system must fit tho se features.TTCN-3 distributed test execution platform was able to fulfill requirements of distributes test.However

with the feature of static binding test adapter

TTCN-3 test system can not communicate with different kinds of SUT sata single test execution node.Therefore the concept of test adapter framework was present in this paper.On the basis of fundamental adaptation with supporting TTCN-3 standard interface

the framework integrated test adapters for different kinds of SUTs

dynamically selected and used adaptive test adapter.As a result

the framework fulfills requirements of TTCN-3 distributed test execution platform

and strengthens the ability of TTCN-3 for distributed test domain as well.
