Question

有时webDriver.quit（）方法会在没有消息的情况下提供异常。但它成功地关闭了浏览器。它只发生在网格上，我无法在本地机器上重现这一点。它可能与并行执行有关，我不知道。异常似乎是随机的，这让我发疯到不知道。

在测试结束时，我的代码块是;

public void close() {
    try {
        webDriver.quit();
    } catch (Exception ex) {
        logger.error("Exception on closing webdriver", ex);
    }
}

错误日志是：

我非常感谢任何帮助或建议。感谢

似乎有时当你退出驱动程序时，你正在打断屏幕截图。也许完成一些IO。

在网格上运行时，您是否获得了预期的屏幕截图？尝试在驱动程序功能中设置takeScreenshot = false并查看是否继续发生。

webDriver.quit（）在没有消息
