ExpectedConditions類在運行硒測試時會拋出許多錯誤

我的測試用於在2月20日之前正常運行。從今天早上開始，我在控制檯上看到許多錯誤。他們看起來像：ExpectedConditions類在運行硒測試時會拋出許多錯誤

顯然這是因爲ExpectedConditions類。

項目編譯成功，我的IDE在任何類中都不顯示任何錯誤。該問題僅在測試運行時期間被觀察到，並且總是會導致測試在某個時候失敗。

我沒有更新瀏覽器或我的pom.xml。週末之前沒事，現在就失敗了。

瀏覽器 - FF 47.0 硒 - 我的代碼3.1.0

示例使用ExpectedConditions類是：

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))); 
    }

你能後的'ExpectedConditions'使用在你的代碼的例子嗎？ – Guy

@Guy我在說明中添加了一段代碼。感謝 –
