  1. 9 core/modules/language/tests/src/Functional/LanguageUILanguageNegotiationTest.php \Drupal\Tests\language\Functional\LanguageUILanguageNegotiationTest

Tests the language UI for language switching.

The uses cases that get tested, are:

  • URL (path) > default: Test that the URL prefix setting gets precedence over the default language. The browser language preference does not have any influence.
  • URL (path) > browser > default: Test that the URL prefix setting gets precedence over the browser language preference, which in turn gets precedence over the default language.
  • URL (domain) > default: Tests that the URL domain setting gets precedence over the default language.

The paths that are used for each of these, are:

  • admin/config: Tests the UI using the precedence rules.
  • zh-hans/admin/config: Tests the UI in Chinese.
  • blah-blah/admin/config: Tests the 404 page.
