driver.asserts().assertElementFound("Page was not loaded",
By.xpath("//div[@id='actionsContainer']"),Constants.LOOKUP_TIMEOUT);

一般来说，使用Selenium 2.0时，web驱动程序应该只在确定页面已加载后才将控制权返回给调用代码。如果没有，您可以调用waitforeleement，它循环调用findelement，直到找到它或超时(可以设置超时)。

driver.asserts().assertElementFound("Page was not loaded",
By.xpath("//div[@id='actionsContainer']"),Constants.LOOKUP_TIMEOUT);

/**
 * Call this method before an event that will change the page.
 */
private void beforePageLoad() {
    JavascriptExecutor js = (JavascriptExecutor) driver;
    js.executeScript("document.mpPageReloaded='notYet';");
}

/**
 * Call this method after an event that will change the page.
 * 
 * @see #beforePageLoad
 * 
 *      Waits for the previous page to disappear.
 */
private void afterPageLoad() throws Exception {
    (new WebDriverWait(driver, 10)).until(new Predicate<WebDriver>() {

        @Override
        public boolean apply(WebDriver driver) {
            JavascriptExecutor js = (JavascriptExecutor) driver;
            Object obj = js.executeScript("return document.mpPageReloaded;");
            if (obj == null) {
                return true;
            }
            String str = (String) obj;
            if (!str.equals("notYet")) {
                return true;
            }
            return false;
        }
    });
}

在只更改部分文档的情况下，您可以从文档更改为元素。

这个技巧的灵感来自于sincebasic的答案。

使用下面的代码，它是非常容易和简单的页面加载。

public void PageLoad(IWebDriver driver, By by)
{
    try
    {
        Console.WriteLine("PageLoad" + by);
        WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(30));
        wait.Until(ExpectedConditions.ElementIsVisible(by));
        wait = new WebDriverWait(driver, TimeSpan.FromSeconds(30)); // 30 seconds wait until element not found. 
        wait.Until(ExpectedConditions.ElementToBeClickable(by));


    }
    catch (Exception ex)
    {

        Console.WriteLine(ex.Message);
        Assert.Fail("Element not found!")
    }
}

我希望这对你有所帮助。

这段代码将等待页面上的所有元素都加载到DOM中。

WebDriver driver = new WebDriver();
WebDriverWait wait = new WebDriverWait(driver, timeout);

wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*")));
