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

Question

我正在尝试启动Mozilla，但仍然出现以下错误：

线程“main”java中出现异常。lang.IllegalStateException：驱动程序可执行文件的路径必须由webdriver设置。壁虎。驱动系统属性；有关更多信息，请参阅https://github.com/mozilla/geckodriver.最新版本可从以下网站下载：https://github.com/mozilla/geckodriver/releases

我使用的是Selenium 3.0.01Beta版和Mozilla 45。我也试过使用Mozilla 47。但还是一样。

Answer 1

Selenium WebDriver Java代码：

从下载Gecko驱动程序https://github.com/mozilla/geckodriver/releases基于你的平台。根据您的选择在某个位置提取。编写以下代码：

System.setProperty("webdriver.gecko.driver", "D:/geckodriver-v0.16.1-win64/geckodriver.exe");
WebDriver driver = new FirefoxDriver();
driver.get("https://www.lynda.com/Selenium-tutorials/Mastering-Selenium-Testing-Tools/521207-2.html");

Answer 2

1. 从seleniumhq网站下载gecko驱动程序（现在它在GitHub上，你可以从这里下载）。
   1. 你会有一个拉链（或tar.gz），所以把它取出来
   2. 提取后你会得到壁虎河。exe文件（linux中适当的可执行文件）
   3. 在C中创建文件夹：名为SeleniumGecko（或适当的）
   4. 复制并粘贴geckodriver。exe到SeleniumGecko
   5. 设置gecko驱动程序的路径如下

   .

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

Answer 3

Selenium客户端绑定将尝试从系统PATH中找到geckocher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。

在Unix系统上，如果使用与bash兼容的shell，可以执行以下操作将其追加到系统的搜索路径：

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中。原理与Unix相同。

下面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以明确启用木偶。在Selenium 3.0及更高版本中，您不需要做任何事情来使用木偶，因为它在默认情况下是启用的。

要在测试中使用木偶，您需要更新所需的功能以使用它。

Java：

作为例外，你需要下载最新的geckodriver。exe从这里下载并设置geckodriver。exe路径，它作为系统属性存在于您的计算机中，带有变量webdriver。壁虎。驱动程序在启动木偶驱动程序并启动firefox之前，如下所示：-

//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); 

对于Selenium3使用：-

WebDriver driver = new FirefoxDriver();

如果你仍然有麻烦，请遵循这个链接，这将有助于你解决你的问题

.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RemoteWebDriver，这将允许您在Selenium网格中使用Marionette。

蟒蛇：

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

Java：

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); 

网

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的Selenium驱动程序一样，Mozilla现在发布了一个可执行文件，它将与浏览器一起运行。请按此了解更多详细信息。
