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.

您还可以使用以下代码检查页面加载

IWait<IWebDriver> wait = new OpenQA.Selenium.Support.UI.WebDriverWait(driver, TimeSpan.FromSeconds(30.00));

 wait.Until(driver1 => ((IJavaScriptExecutor)driver).ExecuteScript("return document.readyState").Equals("complete"));

您可以删除系统。线。添加它是为了调试目的。

WebDriver driver_;

public void waitForPageLoad() {

    Wait<WebDriver> wait = new WebDriverWait(driver_, 30);
    wait.until(new Function<WebDriver, Boolean>() {
        public Boolean apply(WebDriver driver) {
            System.out.println("Current Window State       : "
                + String.valueOf(((JavascriptExecutor) driver).executeScript("return document.readyState")));
            return String
                .valueOf(((JavascriptExecutor) driver).executeScript("return document.readyState"))
                .equals("complete");
        }
    });
}

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。

下面是一个Java 8版本的目前被点赞最多的答案:

WebDriverWait wait = new WebDriverWait(myDriver, Duration.ofSeconds(15));
wait.until(webDriver -> "complete".equals(((JavascriptExecutor) webDriver)
    .executeScript("return document.readyState")));
    

其中myDriver是一个WebDriver对象(前面声明过)。

注意:注意这个方法(document.readyState)只检查DOM。

如果有人使用硒化物:

public static final Long SHORT_WAIT = 5000L; // 5 seconds
$("some_css_selector").waitUntil(Condition.appear, SHORT_WAIT);
