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

WebDriver driver = new ff / chrome / anyDriverYouWish(); .timeouts driver.manage()()。TimeUnit.SECONDS implicitlyWait(10日); 最多等待10秒。 WebDriverWait wait = new WebDriverWait(driver, 10); wait.until (ExpectedConditions。visibilityOf (WebElement元素)); FluentWait <司机> FluentWait; fluentWait = new fluentWait <>(driver)。TimeUnit.SECONDS withTimeout(30日) TimeUnit.MILLISECONDS .pollingEvery (200) . ignore (NoSuchElementException.class);

最后一个选项的优点是可以包含预期的异常，以便继续执行。

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);

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);

NodeJS答案:

在Nodejs中，你可以通过承诺得到它…

如果您编写了这段代码，您可以确保当您到达then…

driver.get('www.sidanmor.com').then(()=> {
    // here the page is fully loaded!!!
    // do your stuff...
}).catch(console.log.bind(console));

如果您编写了这段代码，您将进行导航，selenium将等待3秒……

driver.get('www.sidanmor.com');
driver.sleep(3000);
// you can't be sure that the page is fully loaded!!!
// do your stuff... hope it will be OK...

来自Selenium Documentation (Nodejs):

这一点。get(url)→Thenable<undefined> 调度命令导航到给定的URL。 返回一个承诺，该承诺将在文档完成加载时得到解决。

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.
