Selenium WebDriver Firefox错误 - 无法连接

Question

我做了我的研究,发现了其他相关问题.没有人帮忙.

至今:

• 拥有最新版的硒

• 安装旧版本的Firefox

我在Windows 7上进行了eclipse,我创建了一个.war并在ehost下在localhost:8080/JSPprojectServlets(在W7上)进行了测试,它运行正常.selenium打开firefox,获取url,然后获取源代码.

然后我把.war文件放到tomcat7/webapps下的我的linux(ubuntu)机器上,并尝试用我的Windows 7机器在192.168.1.102:8080/JSPprojectServlets下访问它,但它不起作用,它给出了以下错误:

HTTP Status 500 - Failed to connect to binary FirefoxBinary(/usr/bin/firefox) on port 7055; process output follows:

我的代码看起来像这样

package org.blah.blah;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;


import org.openqa.selenium.WebDriver;

import org.openqa.selenium.firefox.FirefoxDriver;
//import org.openqa.selenium.chrome.ChromeDriver;


public class XmlServlet extends HttpServlet {

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        //System.out.println("Hello from GET method.");
        PrintWriter writer = response.getWriter();
        writer.println("<h3></h3>");

        WebDriver driver = new FirefoxDriver();

        driver.get("http://google.com");

        writer.println(driver.getPageSource());

    }
}

更新:

当我使用HtmlUnitDriver时,它工作192.168.1.102:8080/JSPprojectServlets

很明显,由于某种原因它无法打开Firefox.我在W7 64位,并且还有instaleld FF10,但仍然没有.

尝试将Firefox二进制绝对路径作为代码中的参数,并在从win7调用时将其作为JSP的输入提供,然后它可以解决问题.从上面的堆栈跟踪中可以看出firefox二进制文件在/ usr/bin/firefox中找不到,但是你试图在win7中调用路径不同的webdriver.

接收org.openqa.selenium.WebDriverException:在Selenium IDE中使用Webdriver播放时无法在PATH运行测试中找到firefox二进制文件
