Example text

Let us assume, for the purpose of our example, that the test system has access to a management interface that allows it to control and manipulate the contents of the name server table before or during the execution of tests. This would allow us to control the presence or absence of entries in the mapping table and would provide us with greater control and diversity over what we are testing. In our example, we use procedure-based communication to manage the local name server by using its available management software interface.

If the name server is down or seriously congested for some reason, the test case will still be blocked until a reply comes in, which might never happen. This situation needs to be handled in a better way and can be resolved by using timers. If a timer is started when the DNS question is sent out, we can specify that we require the incoming reply to show up within a given amount of time. 9. A timer called replyTimer is started and set to run for 20 seconds directly after the DNS question is sent.

A new subtype is defined by using the keyword type, followed by the parent type, the name for the newly defined type, and the subtype’s restriction. 3 Subtyping of basic data types module hostLookup { type integer Byte ( 0 .. 3 shows the definition of such a subtype. Any constant or variable of such a subtype is required to conform to the subtype restrictions, and an assignment outside of the allowed values will cause an error, either during compilation or run time. Another useful subtype restriction can be defined via a value list, that is a complete list of all legal values for the subtype.
