qcheck is an autotesting tool similar to Haskell's Quickcheck.
A collection of web pages are written as a user guide for quickcheck.
It covers the syntax and features supported by the current version of
quickcheck.
RELEASE_NOTES:
compiler/notes/authors.html:
extras/README:
Modified to mention quickcheck.
extras/quickcheck/qcheck.m:
New file that contains the source code for qcheck.
extras/quickcheck/rnd.m:
New file written by conway. Its functions are similar
to those in library random.m. The random numbers generated
with random.m functions show strong correlation in lower
bits; rnd.m does not seem have such problems.
