# 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)

#

# fuzzy malloc?

#

# Many database changes maintaining some kind of invariant. 

# Storing checksums etc.

#

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