Cryptography in C and C++, Second Edition

Chapter 18. Do It Yourself: Test LINT

90% of the time is spent in 10% of the code.

——Robert Sedgewick, Algorithms

We have already discussed the topic of testing in Chapter 13, wherewe subjected the basic arithmetic functions of the first part of the book to extensive static and dynamic tests. We now require a similar treatment for the validation of the C++ class LINT, and furthermore, we still must provide tests of the number-theoretic C functions.

The approach of the static tests can be carried over directly to the LINT class, where the tool PC-lint (see [Gimp]) used for the static analysis of C functions will stand us here in good stead as well, since we can use it for checking the syntactic correctness and (within certain bounds) the semantic ...
