Question

我试图在Bamboo弹性实例中运行功能测试。我想在Bamboo Amazon x86_64服务器上运行我的功能测试。在Amazon Linux：默认图像EBS i386（linux）弹性实例中，我安装了Firefox 17.0.1版本来运行我的功能测试。从我的本地机器我希望每晚在我的构建中运行Elastic实例中的功能测试。但是，我收到配置错误。在功能测试pom文件中：

<executions>
    <execution>
        <id>xvfb</id>
        <phase>pre-integration-test</phase>
        <goals>
            <goal>xvfb</goal>
        </goals>
        <configuration>
            <display>:2.0</display>
        </configuration>
    </execution>
    <execution>
        <phase>pre-integration-test</phase>
        <goals>
            <goal>start-server</goal>
        </goals>
        <configuration>
            <background>true</background>
        </configuration>
    </execution>
</executions>

要在Elastic实例中运行无头硒测试，我从pom文件中的build开始Xvfb（X虚拟帧缓冲区）并将Display设置为：2.0
我的测试类设置运行Firefox：

    private WebDriver driver;
    @Before 
    public void setUp() throws Exception {  
    driver = new FirefoxDriver();

在Elastic实例中，这是我进行配置的方式：

已安装firefox版本17.0.1。
还使用命令yum install xorg-x11-server-Xvfb在Elastic实例中安装了Xvfb服务器，以便在命令行中将Display变量设置为：2.0：export DISPLAY=:2.0

然后当我在命令行中键入Firefox时，它会显示
error:cannot open display=:2.0

全部设置为运行我的测试。

当我运行测试时，Selenium服务器是v2.40.0 它显示Xvfb已启动。我检查了弹性实例以查看Xvfb是否正在运行ps aux | grep -i xvf.它正在运行为Xvfb：2.0

一切进展顺利但是在测试时它无法找到Firefox。

有人可以帮我解决这个问题吗？我是否错过了在弹性实例中设置Firefox的一些配置？什么是＆＃34; failed to connect to Firefoxbinary(usr/bin/firefox)＆＃34;？我必须在哪里指明这个？我是否需要在功能测试设置中添加此Firefox二进制文件才能运行Firefox？

Answer 1

这里有几件事。让我们一步一步尝试。

首先，登录ec2实例并运行以下命令..

Xvfb：1-screen 0 1280x768x24＆amp;

export DISPLAY =：1

现在尝试从命令行运行firefox。让我知道这是否有效而不会给你一个错误。

在Bamboo Elastic实例中运行功能测试（Amazon x86_64服务器（linux）（弹性图像））
