I can't see the error. But I assume the problem is your schema format.

config.active_record.schema_format = :sql

in application.rb should be what you need to do.

The reason behind that is by default your test database is not made from a schema only dump of your development database, but, instead from db/schema.rb - which knows nothing about mysql functions.

an sql schema format will do a mysqldump (or pg_dump) with the schema only flag set to true and create a development_structure.sql file.
