Knuth has some description of the test suite for TeX.


He claims that it gets to all parts of the code except for fatal error
processing code. Somewhat iteratively, develop a test, find which
parts of the code it doesn't reach, change it so that it does.


I used to hear stories about using cards from the card recycling bin
for a stress test of compilers. This method seems to have fallen out
of use lately.
