Selenium FireFoxDriver无法连接

Question

我第一次尝试使用Selenium来驱动Firefox。我使用了几乎相同的代码来驱动Chrome，没有问题。但是，当我尝试使用Firefox驱动程序时，浏览器会打开，暂停，然后，大约60秒后，我会得到一个错误报告，内容如下：

Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox   console output:

我检查了其他指南，他们建议我更新我的.jar文件。我正在使用selenium-java-3.0.0-beta2 2和Firefox 48.0.1进行测试，所以我的文件是最新的。我想让它正常运行。

更新:代码仍然不工作，我已经设置了系统属性来正确设置geckodriver。但是，我仍然不能让司机正常工作。它甚至不会再启动浏览器了。

import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.remote.DesiredCapabilities;

public class SimpleFireFoxDriver {


public static void main(String[] args) {

    System.setProperty("webdriver.gecko.driver","C:\\Selenium\\geckodriver.exe");

    DesiredCapabilities capabilities = DesiredCapabilities.firefox();
    capabilities.setCapability("marionette", true);

   WebDriver driver = new FirefoxDriver();

   driver.get("http://www.youtube.com");

   System.out.println("Made it to the promised land");

   driver.quit();

    }

}

编辑: FireFox本身的路径位于这里："C:\Program \Mozilla Firefox\firefox.exe“

Answer 1

发生这种情况是因为您设置了错误的系统属性。您需要按以下方式设置system属性：

System.setProperty("webdriver.gecko.driver","C:\\Selenium\\geckodriver.exe");

Selenium firefox驱动程序希望在启动木偶驱动程序和启动firefox之前设置此系统属性。如果您不设置任何系统属性并尝试实例化火狐驱动程序，那么您将得到以下错误：“驱动程序可执行文件的路径必须由webdriver.gecko.driver系统属性设置。”

希望这能有所帮助。

Answer 2

更改系统属性对我有效。改为：

System.setProperty("webdriver.firefox.marionette","src\\test\\java\\lib\\geckodriver.exe");
driver= new FirefoxDriver();

希望这能有所帮助。

Answer 3

用"webdriver.gecko.driver“换"webdriver.firefox.marionette”救了我的命！示例：

校正

System.setProperty("webdriver.firefox.marionette","C://selenium/gecko/geckodriver.exe");

不正确

System.setProperty("webdriver.gecko.driver","C://selenium/gecko/geckodriver.exe");
