WebDriverException:无法使用GeckoDriver Firefox和Selenium Java连接到二进制FirefoxBinary(C:\ Program Files \ Mozilla Firefox \ firefox.exe) [英] WebDriverException: Failed to connect to binary FirefoxBinary(C:\Program Files\Mozilla Firefox\firefox.exe) with GeckoDriver Firefox and Selenium Java

问题描述

使用Selenium 3.1.0，firefox最新版本72.0，默认firefox驱动程序2.53.1这是我的代码

Using Selenium 3.1.0, firefox latest version 72.0, default firefox driver 2.53.1 here is my code

System.setProperty("webdriver.gecko.driver" ,"C:\\Users\\sindhusha.tummala\\Downloads\\geckodriver.exe");
driver = new FirefoxDriver();

仍然出现错误

org.openqa.selenium.WebDriverException: Failed to connect to binary FirefoxBinary(C:\Program Files\Mozilla Firefox\firefox.exe) on port 7055; 

任何人都可以帮忙吗

推荐答案

此错误消息...

org.openqa.selenium.WebDriverException: Failed to connect to binary FirefoxBinary(C:\Program Files\Mozilla Firefox\firefox.exe) on port 7055; 

...表示 GeckoDriver 二进制文件(可执行文件)无法启动/产生新的浏览上下文，即 Firefox浏览器会话，无法找到FirefoxBinary.

...implies that the GeckoDriver binary (executable) was unable to initiate/spawn a new Browsing Context i.e. Firefox Browser session as it was unable to locate the FirefoxBinary.

当 Firefox 未安装在默认位置或完全未安装时，会出现此问题.

This issue arises when Firefox is not installed at the default location or is not installed at all.

要解决此问题:

• 如果尚未完全安装 Firefox ，则必须安装.
• 如果未在默认位置安装 Firefox ，则需要通过参数传递 Firefox 二进制文件的绝对路径.firefox_binary 如下:

• 代码块:

• If Firefox is not al all installed you have to install it.
• If Firefox is not installed at the default location you need to pass the absolute path of the Firefox binary through the argument firefox_binary as follows:

• Code block:

public class A_Firefox_binary 
{
    public static void main(String[] args) 
    {
        System.setProperty("webdriver.gecko.driver", "C:/Utility/BrowserDrivers/geckodriver.exe");
        FirefoxOptions options = new FirefoxOptions();
        options.setBinary("C:\\path\\to\\firefox.exe");
        WebDriver driver =  new FirefoxDriver(options);
        driver.get("https://stackoverflow.com");
        System.out.println("Page Title is : "+driver.getTitle());
        driver.quit();
    }
}

确保:

• 将 JDK 升级到最新级别 JDK 8u222 .
• 将硒升级到当前级别> 版本3.141.59 > .
• 将 GeckoDriver 升级到 GeckoDriver v0.26.0 级别.
• GeckoDriver存在于所需位置.
• GeckoDriver对非root用户具有可执行权限.
• 将 Firefox 版本升级到 Firefox v70.0 级别.
通过 IDE
• 清理您的项目工作区和重建您的项目，并且仅具有必需的依赖项.
• (仅仅WindowsOS )使用 CCleaner 工具，可消除执行 Test Suite 之前和之后的所有操作系统琐事.
• (仅仅LinuxOS )来卸载. Revo Uninstaller 并安装最新版本的 Web客户端 GA和发行版.
• 进行系统重启.
• 以非root用户身份执行 Test .
• 始终在 tearDown(){} 方法中调用 driver.quit()以关闭&优雅地销毁 WebDriver 和 Web Client 实例.

• Upgrade JDK to recent levels JDK 8u222.
• Upgrade Selenium to current levels Version 3.141.59.
• Upgrade GeckoDriver to GeckoDriver v0.26.0 level.
• GeckoDriver is present in the desired location.
• GeckoDriver is having executable permission for non-root users.
• Upgrade Firefox version to Firefox v70.0 levels.
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• (WindowsOS only) Use CCleaner tool to wipe off all the OS chores before and after the execution of your Test Suite.
• (LinuxOS only) Free Up and Release the Unused/Cached Memory in Ubuntu/Linux Mint before and after the execution of your Test Suite.
• If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
• Take a System Reboot.
• Execute your Test as a non-root user.
• Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.
