gistfile1.txt

When you're using UUID as primary key field your tests will be broken, so to fix it take there steps:

- Remove your db/schema.rb file

- Add the following line in your application.rb file
     config.active_record.schema_format = :sql

- Then after you run your migrations and before you run rake db:test:prepare run:
     rake db:structure:dump


With this your test database will be made with a sql file and import correctly your primary keys
