large_test suite

================



Iggy Galarza 07/20/07

---------------------



This test suite should include any test that requires:

1. Longer than the default timeout to complete.

2. A considerable amount of disk space.



These tests can be completed with the following command:



mysql-test-run.pl --suite=large_tests --big-test --suite-timeout=6360 --testcase-timeout=795
