Question

Selenium版本：3.7.1

我正在自动化java swing应用程序并使用远程Web驱动程序，如下所示：

DesiredCapabilities dc = new DesiredCapabilities();
dc.setBrowserName("java");
dc.setVersion(" ");
dc.setJavascriptEnabled(true);
dc.setPlatform(Platform.ANY);
javaDriverTest = new RemoteWebDriver(new URL("docker container url"), dc);

除了以下内容外，一切正常：

javaDriverTest.switchTo().window(windowName);

我随后得到了这个错误：

这并不是一直发生的。但是经常发生。知道如何修复它吗？

问题似乎与我启动应用程序的方式有关，即，我最初使用了以下内容：

export DISPLAY=:1.0
javaws -J -Dmarathon.agent=file:/root/Downloads/marathon-java-agent-5.1.4.0.jar.........

但是当我在命令中添加Xvfb时

Xvfb :1.0
export DISPLAY=:1.0
javaws -J -Dmarathon.agent=file:/root/Downloads/marathon-java-agent-5.1.4.0.jar.........

它解决了该问题。因此，我相信这个问题确实与RemoteWebDriver无关，而实际上与被测应用程序的启动方式有关。

RemoteWebDriver在调用switchTo（）方法时导致stackoverflow错误
