+By utilizing L<Catalyst::Plugin::ConfigLoader>s functionality for loading
+multiple config files based on environment variables you can override your
+default (production) database connection settings.

+Setting C<$ENV{ MYAPP_CONFIG_LOCAL_SUFFIX }> to 'testing' in your test script
+results in loading of an additional config file named myapp_testing.conf after
+myapp.conf which will override any parameters in myapp.conf.

+You should set the environment variable in the BEGIN block of your test script
+to make sure it's set before your Catalyst application is started.
