Example text

These are question and answer messages. Furthermore, these messages have the same format so a particular flag in the message is needed to indicate if the message is a question message or an answer message. A DNS message also contains an identification field, that is a 16-bit integer generated by the client application in order to allow the client to identify the answer for a previously generated query. Real DNS messages also contain a body part that allows a single DNS message to contain several questions or several answers simultaneously, but in our example we limit the number of questions or answers in a single DNS message to one.

Com". As a question must not contain an answer part, the answer field has been marked absent with the attribute omit. 3 and, that is that the template is rather hard-wired. 3 A send template for our DNS message type // A possible template for the DNS message type. 4 A parameterised send template for our DNS questions // A parameterized template for DNS questions based on DNSMessage. 5 A parameterised receive template for our DNS answers // A parameterized template for DNS answers based on DNSMessage.

Catch( timeout ) { return false; } } } Now that we have our procedure signatures and signatures templates, we are able to start issuing calls to these procedures. Let us assume that our test cases, before starting to communicate with the SUT on its client interface, first make sure to clear the server’s mapping table and then initialise it with a set of known values. 12 shows how a TTCN-3 function can be used to implement the part that clears the mapping table. The function has no parameters but returns a boolean value depending on whether its actions were performed successfully or not.
