# 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')
|
|

# The difference in priority on the territory is best shown with a
|
|
# engine that supports the following locales:
|
|

|
|
|
# A user selects only a language
|
|
self.assertEqual(locales.match_locale('en', locale_tag_list), 'en-GB')

|
|
# fr_FR takes priority ..
|
|

|

# The get_engine_locale selects the locale by looking at the "population
