     * KEYCLOAK-13005: setting the Consumer Service POST Binding URL in the admin console and then deleting it (i.e. erase

     * the admin console sets the value of a field that was previously configured to an empty string instead of null, so the
     * code must verify if the configured URL is not null and non-empty.
     *
     * This test verifies the fix for the issue works by mimicking the behavior of the admin console - i.e. setting an empty
     * string in the {@code saml_assertion_consumer_url_post} attribute. It is expected that in this situation the master
     * URL is picked and redirection to the app works after a successful login.
     *
     * @throws Exception if an error occurs while running the test.
