4 Logically, a name server has an application and a network interface. 5 19 The configuration for our multi component test using four parallel test components. name server is not able to answer on its own. This component will be connected to the application interface of the SUT and run basically the same behaviour that we used in the single component case. A second test component will act as the root server and the third component will take the role of the remote name server, which the root name server specifies as the authoritative server.

We have seen that the language has a long history, which originates from the world of telecommunications. In the past decade, the worlds of telecommunications and the Internet have moved much closer together and the systems to be tested are constantly becoming more dynamic and complex in their nature. To meet these new challenges, the existing standardised test language, TTCN-2, was re-designed and extended to result in TTCN-3. The following chapter introduces an example that, even though simple in nature, contains many of the testing issues found in modern communication systems.

The MTC will wait until all parallel test components have terminated, and then (automatically) calculate the final verdict. 10 Procedure-Based Communication Until now, we have been looking at message-based communication. It is important to highlight that TTCN-3 can also handle procedure-based communication. To give an example of this, we will have a look at a different interface of the local name server that we can control and combine with the tests we have previously defined.
