 # 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.
