使用 Java 的 Selenium - 驱动程序可执行文件的路径必须由 webdriver.gecko.driver system 属性设置

Selenium 客户端绑定将尝试从系统 PATH 中找到 geckodriver 可执行文件。您需要将包含可执行文件的目录添加到系统路径中。

• 在Unix系统上，如果您使用的是bash兼容的shell，则可以执行以下操作将其附加到系统的搜索路径中：

  export PATH=$PATH:/path/to/geckodriver
  

• 在 Windows 上，您需要更新 Path 系统变量以将完整目录路径添加到可执行文件。原理与Unix相同。

以下所有使用任何编程语言绑定启动最新 firefox 的配置都适用于 Selenium2 以显式启用木偶。使用Selenium 3.0及更高版本，您无需执行任何操作即可使用Malioette，因为它默认处于启用状态。

要在测试中使用木偶，您需要更新所需的功能才能使用它。

爪哇 ：

由于异常清楚地表明您需要从这里下载最新的路径，并在启动木偶驱动程序和启动firefox之前将其作为系统属性设置为计算机中存在的下载路径，例如：-geckodriver.exegeckodriver.exewebdriver.gecko.driver

//if you didn't update the Path system variable to add the full directory path to the executable as above mentioned then doing this directly through code
System.setProperty("webdriver.gecko.driver", "path/to/geckodriver.exe");

//Now you can Initialize marionette driver to launch firefox
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
WebDriver driver = new MarionetteDriver(capabilities); 

并用作：-Selenium3

WebDriver driver = new FirefoxDriver();

.NET ：

var driver = new FirefoxDriver(new FirefoxOptions());

蟒蛇

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

caps = DesiredCapabilities.FIREFOX

# Tell the Python bindings to use Marionette.
# This will not be necessary in the future,
# when Selenium will auto-detect what remote end
# it is talking to.
caps["marionette"] = True

# Path to Firefox DevEdition or Nightly.
# Firefox 47 (stable) is currently not supported,
# and may give you a suboptimal experience.
#
# On Mac OS you must point to the binary executable
# inside the application package, such as
# /Applications/FirefoxNightly.app/Contents/MacOS/firefox-bin
caps["binary"] = "/usr/bin/firefox"

driver = webdriver.Firefox(capabilities=caps)

红宝石 ：

# Selenium 3 uses Marionette by default when firefox is specified
# Set Marionette in Selenium 2 by directly passing marionette: true
# You might need to specify an alternate path for the desired version of Firefox

Selenium::WebDriver::Firefox::Binary.path = "/path/to/firefox"
driver = Selenium::WebDriver.for :firefox, marionette: true

JavaScript （Node.js） ：

const webdriver = require('selenium-webdriver');
const Capabilities = require('selenium-webdriver/lib/capabilities').Capabilities;

var capabilities = Capabilities.firefox();

// Tell the Node.js bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.set('marionette', true);

var driver = new webdriver.Builder().withCapabilities(capabilities).build();

使用 RemoteWebDriver

如果您想在任何语言中使用，这将允许您在Grid中使用。RemoteWebDriverMarionetteSelenium

Python：

caps = DesiredCapabilities.FIREFOX

# Tell the Python bindings to use Marionette.
# This will not be necessary in the future,
# when Selenium will auto-detect what remote end
# it is talking to.
caps["marionette"] = True

driver = webdriver.Firefox(capabilities=caps)

红宝石 ：

# Selenium 3 uses Marionette by default when firefox is specified
# Set Marionette in Selenium 2 by using the Capabilities class
# You might need to specify an alternate path for the desired version of Firefox

caps = Selenium::WebDriver::Remote::Capabilities.firefox marionette: true, firefox_binary: "/path/to/firefox"
driver = Selenium::WebDriver.for :remote, desired_capabilities: caps

爪哇 ：

DesiredCapabilities capabilities = DesiredCapabilities.firefox();

// Tell the Java bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.setCapability("marionette", true);

WebDriver driver = new RemoteWebDriver(capabilities); 

.NET

DesiredCapabilities capabilities = DesiredCapabilities.Firefox();

// Tell the .NET bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.SetCapability("marionette", true);

var driver = new RemoteWebDriver(capabilities); 

注意：就像其他浏览器供应商提供给Selenium的其他驱动程序一样，Mozilla现在已经发布了一个可执行文件，它将与浏览器一起运行。有关更多详细信息，请遵循此步骤。

你可以从这里下载最新的geckodriver可执行文件来支持最新的firefox

1. 从seleniumhq网站下载壁虎驱动程序（现在它在GitHub上，你可以从这里下载它）。
   2. 您将有一个拉链（或焦油.gz），因此请将其提取。
   3. 提取后，您将获得geckodriver.exe文件（Linux中相应的可执行文件）。
   4. 在C中创建文件夹：命名为SeleniumGecko（或适当）
   5. 复制并粘贴壁虎驱动器.exe到硒壁虎
   6. 设置壁虎司机的路径如下

.

System.setProperty("webdriver.gecko.driver","C:\\geckodriver-v0.10.0-win64\\geckodriver.exe");
WebDriver driver = new FirefoxDriver();
