Serenity Screenplay没有一个方便的刷新功能，但它应该是微不足道的滚动自己的。

public class Refresh implements Task {

    public Refresh() { }

    public static Refresh thePage() {

        return Tasks.instrumented(Refresh.class);
    }

    @Override
    @Step("{0} refreshes the browser")
    public <T extends Actor> void performAs(T actor) {

        WebDriver driver = BrowseTheWeb.as(actor).getDriver();
        driver.navigate().refresh();
    }
}
