114 You can get rake to generate this file for you using either of:
115 rake rspec:generate_mysql_config
116 rake rspec:generate_sqlite3_config
117
118 If you use mysql, you'll need to create dev and test
119 databases and users for each. To do this, standing
120 in rspec_on_rails, log into mysql as root and then...
121 mysql> source db/mysql_setup.sql;
122
123 There is also a teardown script that will remove
124 the databases and users:
125 mysql> source db/mysql_teardown.sql;
