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);
    }
