+ * 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.
