智能等待，并忽略NoSuchElementException异常

// Waiting 30 seconds for an element to be present on the page, checking
// for its presence once every 500 millisSeconds.
Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)
        .withTimeout(Duration.ofSeconds(30))
        .pollingEvery(Duration.ofMillis(500))
        .ignoring(NoSuchElementException.class);

//wait until the element is returned, the timeout is not returned and throws a TimeOutException
WebElement foo = wait.until(new Function<WebDriver, WebElement>() {
    public WebElement apply(WebDriver driver) {
        return driver.findElement(By.id("foo"));
    }
}); 

PageLoadTimeout命令

目的：设置在抛出错误之前等待页面加载完成的时间。如果超时为负，则页面加载可能是无限期的。

 driver.manage().timeouts().pageLoadTimeout(100, SECONDS);

SetScriptTimeout命令

用途：设置在抛出错误之前等待异步脚本完成执行的时间。如果超时为负，则允许脚本无限期运行。

 driver.manage().timeouts().setScriptTimeout(100,SECONDS);
