显示等待:

//页面加载时间
driver.manage().timeouts().pageLoadTimeout(30,TimeUnit.SECONDS) 
//判断是否加载到元素
WebDriverWait(driver, 15).until(     
 ExpectedConditions.presenceOfElementLocated(By.cssSelector("css locator"))
);

//获得加载的元素
WebElement e = (new WebDriverWait( driver, 10)) .until( 
        new ExpectedCondition< WebElement>(){ 
         public WebElement apply( WebDriver d) { 
                return d.findElement( By.id("id locator")); 
            }
        }

隐试等待:

driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS)

死等:

Tread.sleep();
