我如何要求Selenium-WebDriver在sendkey之后等待几秒钟？

我会不惜一切代价避免使用这样的方法，因为它会减慢测试速度，但是我遇到了我没有其他选择的情况。

public void Wait(double delay, double interval){    // Causes the WebDriver to wait for at least a fixed delay    var now = DateTime.Now;    var wait = new WebDriverWait(myWebDriver, TimeSpan.FromMilliseconds(delay));    wait.PollingInterval = TimeSpan.FromMilliseconds(interval);    wait.Until(wd=> (DateTime.Now - now) - TimeSpan.FromMilliseconds(delay) > TimeSpan.Zero);}

总是最好以某种方式观察DOM，例如：

public void Wait(Func<IWebDriver, bool> condition, double delay){    var ignoredExceptions = new List<Type>() { typeof(StaleElementReferenceException) };    var wait = new WebDriverWait(myWebDriver, TimeSpan.FromMilliseconds(delay)));    wait.IgnoreExceptionTypes(ignoredExceptions.ToArray());    wait.Until(condition);}public void SelectionIsDoneDisplayingThings(){    Wait(driver => driver.FindElements(By.ClassName("selection")).All(x => x.Displayed), 250);}
