The problem is that currently there is no way to test the behavior of the mysql_change_user() function using the mysqltest suite because there is no internal command for it. The solution is to introduce a change_user command that can be used to test aspects of the MySQL client function mysql_change_user(). client/mysqltest.c: Add change_user command to mysqltest. mysql-test/r/mysqltest.result: Add test case result for change_user command mysql-test/t/mysqltest.test: Add test case for change_user command mysql-test/r/change_user.result: Add new file with test case results for bugs 20023 and 31418. mysql-test/t/change_user.test: Add new file with test cases for bugs 20023 and 31418.
