mysql-test/README

+This directory contains a test suite for mysql daemon. To run
+the currently existing test cases, simply execute ./mysql-test-run in
+this directory. It will fire up the newly built mysqld and test it.
+Note that you do not have to have to do make install, and you could
+actually have a co-existing MySQL installation - the tests will not
+conflict with it.
+
+All tests must pass. If one or more of them fail on your system, please
+report the details to bugs@lists.mysql.com
+
+You can create your own test cases. To create a test case:
+
+ cd t
+ vi test_case_name.test
+
+ in the file, put a set of SQL commands that will create some tables,
+ load test data, run some queries to manipulate it.
+
+ then do ./mysql-test-run -record test_case_name
+ and look at r/test_case_name.result - edit the result if necessary. If you
+ have to edit it, you have found a bug.
+
+To submit your test case, put your .test file and .result file(s) into
+a tar.gz archive, add a README that explains the problem, ftp the 
+archive to ftp://support.mysql.com/pub/mysql/secret/ and send  a mail
+to bugs@lists.mysql.com
+
+
+

mysql-test/README.gcov

+To be able to see the level of coverage with the current test suite,
+do the following:
+
+  - make sure gcov is installed
+  - compile with BUILD/compile-pentium-gcov ( if your machine is not pentium, hack
+this script, or just live with the pentium-specific stuff)
+  - ./mysql-test-run -gcov
+  - to see the level of coverage for a given source file:
+     grep source_file_name /tmp/gcov.out
+  - to see which lines are not yet covered, look at source_file_name.gcov in the source tree. Then think hard about a test case that will cover those
+lines, and write one!
