Question about test cases in "mysql-test" directory

[Tianyin Xu]

Hi all,

I want to take the advantage of the existing MySQL test suite to do
some specific testing.

According to the manual, the test suite is located in the mysql-test
directory (under the install root directory).

What confused me is that there're two different test suite directories
there -- (1) mysql-test/t and (2) mysql-test/suite.

It seems that when executing
#mysql-test-run
it would execute the tests under "suite" directory, but the examples
in README, e.g.,
#mysql-test-run --extern alias analyze
the "alias" and "analyze" refer to the test cases in the "t" directory.

Could anyone tell me what's the different between the tests in these
two directory? Which is doing what?

Thanks a lot!
