+If you want to use an already running MySQL server for specific tests,

+For example, here is the command to run the "alias" and "analyze" tests

+

+To match your setup, you might also need to provide --socket, --user, and

+With no test cases named on the command line, mysql-test-run falls back
+to the normal "non-extern" behavior. The reason for this is that some

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:
+  - Make sure gcov is installed
+  - Compile the MySQL distribution with BUILD/compile-pentium-gcov (if your
+    machine does not have a pentium CPU, hack this script, or just live with
+	the pentium-specific stuff)
+  - In the mysql-test directory, run this command: ./mysql-test-run -gcov
