Figure 17.13b) shows a Sequence Diagram of the test case testSearchNextElement(),
which returns a verdict as its result. The test case starts with the test
context instance SlaveRoamingListTest and firstly creates two instances RList and
emptyList of type SlaveRoamingList. RList has the entries [”M1”,”M2”,”M3”] meaning
that whenever the link quality between the current master and the slave
becomes bad, Master M1 should be the successory master, otherwise Master M2
and M3, respectively. emptyList has no entries. It is created to check whether
the method recognizes an empty list and thus send warning messages to the
environment.
After the two roaming list instances are created, RList is asked to provide the
next element of the roaming list. According to the ordering of the roaming list,
the return value is M1. After that, the test is finished and a verdict of value pass
