WebDriver 页面等待

selenium2.4.0版本提供了页面等待处理。

显示等待元素可见：

 protected void WaitElementVisible(By by,int timeOutInSeconds,
             long pollingInterval) {
         WebDriverWait wait = new WebDriverWait(driver, timeOutInSeconds);
         wait.pollingEvery(pollingInterval, TimeUnit.MILLISECONDS);
         wait.withMessage(String.format("Timeout waiting for element: %s", locator));
         wait.until(ExpectedConditions.visibilityOfElementLocated(by));
     }

隐式等待：

 protected void Waitfor(By by,int timeOutInSeconds,
             long pollingInterval) {
         driver.manage().timeouts().implicitlyWait(timeOutInSeconds, TimeUnit.SECONDS);
     }
