The best way to wait for page loads when using the Java bindings for WebDriver is to use the Page Object design pattern with PageFactory. This allows you to utilize the AjaxElementLocatorFactory which to put it simply acts as a global wait for all of your elements. It has limitations on elements such as drop-boxes or complex javascript transitions but it will drastically reduce the amount of code needed and speed up test times. A good example can be found in this blogpost. Basic understanding of Core Java is assumed.

如果你设置了驱动程序的隐式等待，然后调用findElement方法在你期望加载页面上的元素上，WebDriver将轮询该元素，直到找到该元素或达到超时值。

driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

在Webdriver/Selenium 2软件测试工具中有两种类型的等待。一种是隐式等待，另一种是显式等待。两者(隐式等待和显式等待)在WebDriver中都很有用。使用等待，我们告诉WebDriver在进入下一步之前等待一定的时间。可以使用隐式等待来等待页面加载。

driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

使用类WebDriverWait

您可以期望显示一些元素。类似于c#:

WebDriver _driver = new WebDriver();
WebDriverWait _wait = new WebDriverWait(_driver, new TimeSpan(0, 1, 0));

_wait.Until(d => d.FindElement(By.Id("Id_Your_UIElement")));

在python中，你可以简单地使用:

driver.implicitly_wait(30)

你可以使用下面的代码片段来加载页面:

    IWait wait = new OpenQA.Selenium.Support.UI.WebDriverWait(driver,TimeSpan.FromSeconds(30.00));
    wait.Until(driver1 => ((IJavaScriptExecutor)driver).ExecuteScript("return document.readyState").Equals("complete"));

或者你可以使用waiter的任何元素被加载，并成为可见/可点击的页面上，最有可能的是，这将是在加载结束时加载，如:

    Wait.Until(ExpectedConditions.ElementToBeClickable(By.XPath(xpathOfElement));
    var element = GlobalDriver.FindElement(By.XPath(xpathOfElement));
    var isSucceededed = element != null;
