我正在用Java编写Selenium / WebDriver中的自动化测试用例。我实现了以下代码来轮询现有的WebElements,但由于我不是Java的专家,我想知道是否有更简洁的方法来编写此方法:
/** selects Business index type from add split button */
protected void selectBusinessLink() throws Exception
{
Calendar rightNow = Calendar.getInstance();
Calendar stopPolling = rightNow;
stopPolling.add(Calendar.SECOND, 30);
WebElement businessLink = null;
while (!Calendar.getInstance().after(stopPolling))
{
try
{
businessLink = findElementByLinkText("Business");
businessLink.click();
break;
}
catch (StaleElementReferenceException e)
{
Thread.sleep(100);
}
catch (NoSuchElementException e)
{
Thread.sleep(100);
}
catch (ElementNotVisibleException e)
{
Thread.sleep(100);
}
}
if (businessLink == null)
{
throw new SystemException("Could not find Business Link");
}
}
这条特殊的界限让我觉得代码有点脏:
while (!Calendar.getInstance().after(stopPolling))

你可以做这样的事情
long t = System.currentMillis(); // actual time in milliseconds from Jan 1st 1970.
while (t > System.currentMillis() - 30000 ) {
...

如何以毫秒使用系统时间?
Calendar calendar = Calendar.getInstance();
calendar.add(Calendar.SECOND, 30);
long stopPollingTime = calendar.getTimeInMillis();
while (System.currentTimeMillis() < stopPollingTime) {
System.out.println("Polling");
try {
Thread.sleep(100);
} catch (InterruptedException e) {
}
}
