Well, with
JM
ock you don't have to do that; the
JM
ock
JU
nit runner takes care of this,
and in case any of the expected calls were not made, the test will fail.
Following the pattern from the previous section about EasyMock, let's rework list-
ing 7.12, shown in listing 7.18, showing the
WebClient
test, this time using
JM
ock.
