Question

在我们的项目中，决定使用ui-tests作为单元测试。为此我们写了几个测试。他们都使用一个端口。在运行测试之前，我从命令行执行命令（通过CI）：nohup Xvfb :2 -screen 0 1920x1080x24 & chromedriver --whitelisted-ips --port = 60000（当然，DISPLAY和PATH在同一会话中设置）。

如果测试后浏览器没有关闭，它可以正常工作。但我们不能这样做。每次测试后必须关闭。如果我这样做：

} finally {
   browser.quit();
}

第一次测试没问题。但在此之后，我们有挂起进程chromedriver，并使用了端口60000（那些，我无法运行监听器：chromedriver --whitelisted-ips --port = 60000等等）。接下来的测试失败了：

我尝试在测试开始时从java代码运行监听器，如下所示：

 Runtime.getRuntime().exec("export DISPLAY=:2 & export PATH=$PATH:/usr/lib/chromium-browser/ & nohup Xvfb :2 -screen 0 1920x1080x24 & chromedriver --whitelisted-ips --port=60000");

并且在最后一个块中我几乎试图杀死进程：

Runtime.getRuntime().exec("pkill chromedriver");

但没有改变。

使用browser.quit（）在单元测试中使用chromedriver
