the remaining input s moves the IUT to its final state q
j
or q
j
. These
two phases are shown in Figure 3.17.
When the IUT is started in its initial state, say q
0
, and excited with
test t, it consumes the string r and arrives at some state q
i
as shown in
Figure 3.17. The output generated so far by the IUT is u, where u =
O(q
0
, r). Continuing further in state q
i
, the IUT consumes symbols
in string s and arrives at state q
j
.The output generated by the IUT
