Research on test adapter framework for distributed TTCN-3 test execution platform

Because distributed system had features of physical distribution, simultaneous access, being sensitive to sequence and platform isomerism, distributed test system must fit those 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 SUTs at a 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.
