# Test plan:
#
# The general principle is to run those SQLite tests that use
# pseudo-random data in some way over and over again for a very 
# long time. The number of tests run depends on the value of 
# global variable $TIMEOUT - tests are run for at least $TIMEOUT 
# seconds.
#
#   fuzz.test     (pseudo-random SQL statements)
#   trans.test    (pseudo-random changes to a database followed by rollbacks)
#   fuzz_malloc.test
#   corruptC.test (pseudo-random corruption to a database)
#
# Many database changes maintaining some kind of invariant. 
# Storing checksums etc.
#

# List of test files that are run by this file.
