我在第四次测试中得到了StaleElementReferenceException。我尝试使用显式等待忽略异常并等待该元素可点击，这在本论坛ref：How to avoid "StaleElementReferenceException" in Selenium?中的类似问题中提出。

代替 -
driver.findElement(By.xpath("//a[@id='tdb2']/span[2]")).click();
尝试以下代码 -
element = driver.findElement(By.xpath("//a[@id='tdb2']/span[2]"));
JavascriptExecutor executor = (JavascriptExecutor)driver;
executor.executeScript("arguments[0].click();", element);
伙计们，我找到了这个问题的解决方案。在单击操作迭代所有可用元素之后，jvm被卡在while循环中。当找到元素时，必须使用'break'语句分支出循环。请参考以下代码：
原始代码：@Test 4
while(itr.hasNext())
{
if((itr.next().getText()).equals(str))
{
itr.next().click();
}
}更新的代码：
while(itr.hasNext())
{
if((itr.next().getText()).equals(str))
{
itr.next().click();
break;
}
}第5版TestScript也是如此。
