ExpectedConditions类在运行硒测试时会抛出许多错误

我的测试用于在2月20日之前正常运行。从今天早上开始，我在控制台上看到许多错误。他们看起来像：ExpectedConditions类在运行硒测试时会抛出许多错误

显然这是因为ExpectedConditions类。

项目编译成功，我的IDE在任何类中都不显示任何错误。该问题仅在测试运行时期间被观察到，并且总是会导致测试在某个时候失败。

我没有更新浏览器或我的pom.xml。周末之前没事，现在就失败了。

浏览器 - FF 47.0 硒 - 我的代码3.1.0

示例使用ExpectedConditions类是：

public void fluentWaitIgnoringNoSuchElementExceptionAndElementNotVisibleException(final String locator){ 
     long waitingTime = 30; 
     long pollingInterval = 500; 
     Wait<WebDriver> wait = new FluentWait<WebDriver>(driver) 
       .withTimeout(waitingTime, TimeUnit.SECONDS) 
       .pollingEvery(pollingInterval, TimeUnit.MILLISECONDS) 
       .ignoring(NoSuchElementException.class) 
       .ignoring(ElementNotVisibleException.class) 
       .withMessage("Fluent wait of " + waitingTime + " seconds with " + pollingInterval + " milliseconds polling interval was unable to locate element with locator " + locator); 
     wait.until(ExpectedConditions.presenceOfElementLocated(By.xpath(locator))); 
    }

你能后的'ExpectedConditions'使用在你的代码的例子吗？ – Guy

@Guy我在说明中添加了一段代码。感谢 –
