# Tests from the commit message of 9ae409a05a
# Assumption:
# A. When a user selects a language the results should be optimized according to
# the selected language.
#
# B. When user selects a language and a territory the results should be
# optimized with first priority on territory and second on language.
# Assume we have an engine that supports the following locales:
locale_tag_list = ['zh-CN', 'zh-HK', 'nl-BE', 'fr-CA']
# Examples (Assumption A.)
# ------------------------
# A user selects region 'zh-TW' which should end in zh_HK.
# hint: CN is 'Hans' and HK ('Hant') fits better to TW ('Hant')
self.assertEqual(locales.match_locale('zh-TW', locale_tag_list), 'zh-HK')
# A user selects only the language 'zh' which should end in CN
self.assertEqual(locales.match_locale('zh', locale_tag_list), 'zh-CN')
# A user selects only the language 'fr' which should end in fr_CA
self.assertEqual(locales.match_locale('fr', locale_tag_list), 'fr-CA')
# The difference in priority on the territory is best shown with a
# engine that supports the following locales:
locale_tag_list = ['fr-FR', 'fr-CA', 'en-GB', 'nl-BE']
# A user selects only a language
self.assertEqual(locales.match_locale('en', locale_tag_list), 'en-GB')
# hint: the engine supports fr_FR and fr_CA since no territory is given,
# fr_FR takes priority ..
self.assertEqual(locales.match_locale('fr', locale_tag_list), 'fr-FR')
# Examples (Assumption B.)
# ------------------------
# A user selects region 'fr-BE' which should end in nl-BE
self.assertEqual(locales.match_locale('fr-BE', locale_tag_list), 'nl-BE')
# If the user selects a language and there are two locales like the
# following:
locale_tag_list = ['fr-BE', 'fr-CH']
# The get_engine_locale selects the locale by looking at the "population
# percent" and this percentage has an higher amount in BE (68.%)
# compared to CH (21%)
