-------------- My model users.rb ------------------

validates_length_of :email, :within => 3..100, :too_short =>
:email_short, :too_long => :email_long

--------- My translations in pl.yml ------------- The below works when i use the application the standard way through WWW.
this does not get read only within test envifronment.

pl:
(...) activerecord:

(...)
errors:
  (...)
  full_messages:
    email_short: "my message 1 {{count}}"
    email_long: "my message 2 {{count}}"

(...)

---------------- QUESTION/BUG? -------------------------

How do I avoid this testing error? I am not using this translation node
" pl, activerecord, errors, models, user, attributes, email, email_short" but a full_mesage instead (cos I need a specific message,
not a {attribute} {message} pair, it will not work in my language).
