Selenium测试不会使用FirefoxDriver在jenkins中运行，在本地桌面上运行良好

Question

我试图让我的硒测试在詹金斯运行，但面临以下问题。当使用maven test或intellij运行时，测试在我的本地计算机上运行得很好。

Firefox 39 x64 Selenium 2.46.0 SeleniumHQ插件（自动更新，所以应该是最新版本）

根据这个Xvfb服务器应该正在运行

Xvfb starting$ Xvfb :1 -screen 0 1024x758x16 -fbdir /data/jenkins/xvfb-64-6044594236651529452.fbdir

问题出在哪里？我在网上搜索了两天，尝试了几乎所有我找到的东西后，我想不出来了。

资料来源：

public void setUp() throws Exception {
        String Xport = System.getProperty("lmportal.xvfb.id", ":1");
        FirefoxBinary firefoxBinary = new FirefoxBinary();
        firefoxBinary.setEnvironmentProperty("DISPLAY", Xport);
        driver = new FirefoxDriver(firefoxBinary, null);
        baseUrl = BASE_URL;
        driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
    }

错误：

org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:

是否正在设置显示环境变量？这需要设置，以便在无头模式下执行测试。

我们使用Xvnc Jenkins插件在作业设置中为变量分配一个随机数：

下面还有一个非常有用的指南，可以帮助您使用Jenkins启动和运行无头测试：
