Test
To test the intermediate representation we have to check the correctness of
both the internal static representation and the serialized form. The simpli-
fied test class
TestDOM
performs these two checks for the specific case of the
page described in Figure 8.6. The test method
testStaticStructure()
checks if
the structure of the internal representation conforms to the structure pre-
sented in Figure 8.7. The test method
testSerialize()
checks if the result of the
serialization is as expected; it verifies the presence of given substrings in the
output (as done in Chapter 6 for the calculator).
