geckodriver连接被拒绝

Question

我试着让我的selenium测试在debian服务器上运行，但是我一直从我的GeckoDriver得到连接拒绝错误。在运行Ubuntu的本地机器上，它运行得很好。你们谁知道怎么了？我找不到任何有用的东西。

OS：Debian Jessie
构建工具：Gradle
Java-版本：8

设置方法

    public static void setUp() {
        //System.setProperty("webdriver.gecko.driver", "geckodriver.exe"); //For debugging in windows
        System.setProperty("webdriver.gecko.driver", "geckodriver"); //for execution on linux

        //Bypass System.err while loading Webdriver
        PrintStream err = System.err;
        System.setErr(new PrintStream(new NullOutputStream()));
        driver = new FirefoxDriver();
        System.setErr(err);

        webDriverWait = new WebDriverWait(driver, 1000);
    }

Answer 1

我终于知道是什么导致了这个问题，我通过ssh开始了测试，因此geckodriver没有工作。您必须添加export display=:0才能使其正常工作。这告诉Firefox如何使用显示服务器。
