抛出它的java代码行:

File srcFile=((TakesScreenshot)驱动程序).getScreenshotAs(OutputType.File)

该代码在多台机器上运行良好,但在尝试在新机器上安装后,我遇到此错误


有人知道是什么引起的吗?我从一个容器运行应用程序

经过多次尝试,没有什么东西可以帮助解决这个问题:

  • 检查您尝试截图的元素的可见性。我试着拍一张桌子的照片,但是里面有一些看不见的元素,这让程序崩溃了

    if(element.isDisplayed())

  • 停止元素并创建一个拼图:一行一行地绘制并使用
BufferedImage bi=new BufferedImage(element.getSize().width,element.getSize().height,BufferedImage.TYPE_INT_RGB)

  • 等待使用以下命令加载元素:

    WebDriverWait wait=newwebdriverwait(驱动程序,300);
    wait.until(预期条件。元素的可视性)(By.id(“报告表”));
    wait.until(webDriver->((JavascriptExecutor)webDriver).executeScript(“return document.readyState”).equals(“complete”)
