-/**
- * 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.
- *
- * @group language
