To quickly assess the difficulty of the text, read a short excerpt:
If there are any errors in D then every test meeting C must be unsuccessful. C is therefore reliable, and since it is non-empty, it is also valid. If C is both valid and reliable, then the presence of any error guarantees ttat every test meeting C will be unsuccessful. D CXir characterization of a good test criterion is thus coextensive with that of Goodenough and Gerhart, although as noted earlier, the attempt to cover all possible errors with a single test criterion is unlikely to be successf...ul . 12 The second special case occurs wtien the criterion allows any subset of S as a test case. The two parameters then become one, and we say that a sub- danain S is revealing if the occurrence of an error is S inplies the failure of any subset of S. In other words, there is an error in S if and only if all inputs in S produce errors. The conjunction of these two special cases inplies that eitlner the program is correct or the program processes every input incorrectly. Clearly tiiis is not likely to occur frequently, nor will we know when it does occur.
