In my Rails project, I have a factory file that contains a lot of factories like this :

```
FactoryGirl.define do
  factory :'59000', class: PostalCode do
    value "59000"
    name "toto"
  end
  factory :'59800', class: PostalCode do
    value "59800"
    name "toto"
  end
  factory :'59777', class: PostalCode do
    value "59777"
    name "toto"
  end
  factory :'59910', class: PostalCode do
    value "59910"
    name "toto"
  end
  factory :'59170', class: PostalCode do
    value "59170"
    name "toto"
  end
  factory :'59155', class: PostalCode do
    value "59155"
    name "toto"
  end
  factory :'59510', class: PostalCode do
    value "59510"
    name "toto"
  end
  factory :'59259', class: PostalCode do
    value "59259"
    name "toto"
  end

  ...

end

```

Do you know how I can build/create all the factories this file contains before the test suite ?

Thanks,
Jules
