Problem

• Finding all translations by parsing is impossible for dynamic calls
• often even static calls are not found
• some file formats do not have a gettext parser

Solution

• log all translations during test execution
• write them to an parseable temp file
• use gettext:find / gettext:pack as usual
• missing translation = missing test, write tests!

Usage

Create a rake task:

#lib/tasks/gettext_test_log.rake
desc "write all msgids used into testlog_phrases.rb"
task :gettext_test_log => :environment do
  #place the file should somewhere your updatepo is searching
  GettextTestLog::write_test_log("locale/testlog_phrases.rb",
    :exclude_msgids_in_po_files=>[
      'some_po_file_that_contains_translations_you_do_not_need.po'
    ]
  )
end

Add to your spec_helper:

#spec/spec_helper.rb
GettextTestLog::activate_test_logging

Run:

rake gettext_test_log
rake gettext:find  #find new translations
#fill newly found translations
rake gettext:pack #write translations

Install

• As Rails plugin: script/plugin install git://github.com/grosser/gettext_test_log.git
• As gem: sudo gem install grosser-gettext_test_log -s http://gems.github.com/

Examples output
