Question

当网络驱动程序找到所需的元素，在其中键入文本，然后引发WebDriverTimeout异常时，是否有人花太多时间才能找到与发送文本相同的元素，有人遇到过问题吗？如果我将这段代码包装在捕获超时异常的try-catch中，则测试会成功进行，但这似乎不是执行此操作的健康方法。

我正在使用c＃硒和chromedriver 2.44

更新：初始等待配置和操作本身：

var driver = new ChromeDriver();
driver.Manage().Timeouts().PageLoad = TimeSpan.FromSeconds(20);
driver.Manage().Timeouts().AsynchronousJavaScript = TimeSpan.FromSeconds(3);
driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(2);

...
var searchLocator = By.Id("searchByName");
driver.GetElement(searchLocator, 20, element => element.Displayed).SendKeys("test");

GetElement扩展名：

public static IWebElement GetElement(this IWebDriver driver, By locator, double timeout, Func<IWebElement, bool> condition)
{
  var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(timeout));
  wait.IgnoreExceptionTypes(typeof(StaleElementReferenceException));
  wait.Until(drv =>
    { 
      var element = driver.FindElement(locator);
      return condition(element);
    });

   return driver.FindElement(locator);
}

您应该能够使用驱动程序上的管理方法来设置各种超时范围。其中之一应该可以解决问题：

driver.Manage().Timeouts().PageLoad = TimeSpan.FromSeconds(30);
driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(30);

您还可以在ctor中指定超时，例如：

var driver = new ChromeDriver (pathToDriver, TimeSpan.FromSeconds (30))

在构造函数中，超时是命令超时that。不知道哪一个适合您。可能您需要的是隐式等待。
